Biopesticides, and nano-biopesticides such as viruses, bacteria, fungi, algae, and nematodes are currently being used in a huge amount and their importance is increasing day by day because pesticides are already created a harmful effects on our health and environment. Due to the chemicals pesticides, diseases are increased in a high rate and food quality is decreased because toxicity level is increased. Biopesticides are best alternative to chemicals pesticides and best results to control pest control programs. The virulence of many biopesticides such as bacteria, fungus, and plant product were tested in laboratory and evaluated under field conditions and successfully approval by government. Biopesticide products are now sold in market for the control of pest and diseases. The aim of biopesticide research is to make these biopesticide products available at field level at a reasonable price and this would become a possible step in the integrated pest management strategy. Moreover, biopesticide research is still going on and in future more products are needed in aspects of bioformulation and areas such as commercialization. This review paper has the important and basic mode of action of major biopesticides in the past. The future prospects for the development of new biopesticides are also discussed such as nano- biopesticides.

Full textAbstract:
The advent of the “Green Revolution” was a great success in significantly increasing crop productivity. However, it involved high ecological costs in terms of excessive use of synthetic agrochemicals, raising concerns about agricultural sustainability. Indiscriminate use of synthetic pesticides resulted in environmental degradation, the development of pest resistance, and possible dangers to a variety of nontarget species (including plants, animals, and humans). Thus, a sustainable approach necessitates the exploration of viable ecofriendly alternatives. Plant-based biopesticides are attracting considerable attention in this context due to their target specificity, ecofriendliness, biodegradability, and safety for humans and other life forms. Among all the relevant biopesticides, plant essential oils (PEOs) or their active components are being widely explored against weeds, pests, and microorganisms. This review aims to collate the information related to the expansion and advancement in research and technology on the applications of PEOs as biopesticides. An insight into the mechanism of action of PEO-based bioherbicides, bioinsecticides, and biofungicides is also provided. With the aid of bibliometric analysis, it was found that ~75% of the documents on PEOs having biopesticidal potential were published in the last five years, with an annual growth rate of 20.51% and a citation per document of 20.91. Research on the biopesticidal properties of PEOs is receiving adequate attention from European (Italy and Spain), Asian (China, India, Iran, and Saudi Arabia), and American (Argentina, Brazil, and the United States of America) nations. Despite the increasing biopesticidal applications of PEOs and their widespread acceptance by governments, they face many challenges due to their inherent nature (lipophilicity and high volatility), production costs, and manufacturing constraints. To overcome these limitations, the incorporation of emerging innovations like the nanoencapsulation of PEOs, bioinformatics, and RNA-Seq in biopesticide development has been proposed. With these novel technological interventions, PEO-based biopesticides have the potential to be used for sustainable pest management in the future.

Abstract Problems that are often encountered in increasing the production of large chili plants are pests and diseases. Some important pests that generally attack chili plants are armyworms, aphids, fruit flies, and mites. The study aimed to obtain citronella biopesticides that were effective in controlling fruit fly pests on large chili plants, using a randomized block design (RBD) with 5 levels of treatment and 5 repetitions. Biopesticide treatment consisted of citronella ash biopesticide (Ts4), citronella extract (Ts3), citronella oil (Ts2), existing (Ts1), and without biopesticide (Ts0). The results showed that citronella oil biopesticides (Ts2) had better potency than other biopesticides and controls. All citronella biopesticide treatments have low effectiveness against fruit fly pests (<40%). The main weather factor is high-intensity rain which greatly affects the effectiveness of biopesticide in the process of controlling fruit flies. Economically, the application of citronella biopesticides technology and existing biopesticides is beneficial for businesses. The value of income per hectare from large chili farming starts from the highest to the lowest respectively: treatment Ts2 (income Rp. 60,977,000 with a B/C ratio = 2.640), Ts3 (income Rp. 57,852,000 with a B/C ratio = 2.516), Ts1 (income Rp. 57,527,000 with a B/C ratio = 2.504), Ts4 (income Rp. 53,952,000 with a B/C ratio = 2.346) and Ts0 (income Rp. 46,852,000 with a B/C ratio = 2.171). With an average B/C ratio of > 1, it means that the citronella biopesticide technology is feasible to be developed to control fruit fly pests on large chili plants.

Full textAbstract:
Synthetic pesticides are well-known not just for their efficiency in pest control, but also for their adverse effects on humans, ecology, and living biome's ecological relationships. Biopesticides are biodegradable, environment-friendly, and non-destructive insecticides that are safe for creatures. They leave no harmful residues in food or feed. Botanical, microbiological, and biochemical biopesticides are the three types of biopesticides. 3,000 tons of biopesticides are produced every year, accounting for around 2.5% of the overall pesticide market. Biopesticides are currently accessible in a variety of forms, including dust, granules, powders, emulsions, suspension concentrates, and so on. The Central Insecticide Board and Registration Committee (CIBRC) in India requires data on chemistry, bioefficacy, toxicity, packaging, and labeling to register biopesticides. Although India has registered 970 biopesticide products, lesser effectiveness, shorter shelf-life, lack of knowledge, and lengthy registration process remain hurdles. New and improved formulation methods might improve biopesticide efficacies, self-lives, and climate resiliency while lowering prices and making them economically competitive with synthetic chemicals. The main types of biopesticides, their benefits and downsides, worldwide and Indian market scenarios, formulations, registration procedures, and current advancements for users and environment-friendly applications and sustainable agriculture are all covered in this review article.

Full textAbstract:
Microbial biopesticides include several microorganisms like bacteria, fungi, baculoviruses, and nematode-associated bacteria acting against invertebrate pests in agro-ecosystems. The biopesticide sector is experiencing a significant growth and many discoveries are being developed into new biopesticidal products that are fueling a growing global market offer. Following a few decades of successful use of the entomopathogenic bacterium Bacillus thuringiensis and a few other microbial species, recent academic and industrial efforts have led to the discovery of new microbial species and strains, and of their specific toxins and virulence factors. Many of these have, therefore, been developed into commercial products. Bacterial entomopathogens include several Bacillaceae, Serratia, Pseudomonas, Yersinia, Burkholderia, Chromobacterium, Streptomyces, and Saccharopolyspora species, while fungi comprise different strains of Beauveria bassiana, B. brongniartii, Metarhizium anisopliae, Verticillium, Lecanicillium, Hirsutella, Paecilomyces, and Isaria species. Baculoviruses are species-specific and refer to niche products active against chewing insects, especially Lepidopteran caterpillars. Entomopathogenic nematodes (EPNs) mainly include species in the genera Heterorhabditis and Steinernema associated with mutualistic symbiotic bacteria belonging to the genera Photorhabdus and Xenorhabdus. An updated representation of the current knowledge on microbial biopesticides and of the availability of active substances that can be used in integrated pest management programs in agro-ecosystems is reported here.

Abstract. Increased use of biopesticides has spurred demand for efficient and effective delivery systems. To this goal, laboratory tests were conducted to investigate six different classes of biopesticides discharged from five different types of flat-fan nozzles, each with three flow capacities. The biopesticide classes were horticultural oil insecticide (HOI), bacterial biofungicide (BBF), botanical extract bio-insecticide (BEBI), liquid fungal bio-insecticide (FBI-ES), wettable powder fungal bio-insecticide (FBI-WP), and mineral salt biofungicide (MSBF). Droplet size distribution, spray pattern width, spray deposition, and coverage on plant leaves and water-sensitive paper (WSP) were the spray parameters tested. These parameters varied greatly with biopesticide class, nozzle type, and nozzle flow capacity. The DV0.5 of the biopesticides ranged from 75 to 519 µm for 0.76 L min-1 nozzles, from 86 to 509 µm for 1.51 L min-1 nozzles, and from 99 to 622 µm for 2.25 L min-1 nozzles. The use of different biopesticides with the same nozzle significantly altered the spray pattern width. Compared to a water-only solution, the largest change of spray pattern width was 14.7% for the air-induction nozzle (AI11004) discharging FBI-ES. The amount of spray deposited on plant leaves for all tested biopesticides (except HOI) did not vary significantly with different nozzle types. However, the air-induction nozzles produced the most uneven spray deposition patterns. Therefore, to achieve optimal spray application efficiency and effectiveness for discharging specific classes of biopesticide, the choice of the proper nozzle type and flow capacity is critical. Keywords: Biopesticide, Crop protection, Deposition, Droplet size, Spray coverage.

Abstract This article aims to provide an overview of nanobiopesticides as a promising solution for sustainable and environmentally friendly pest control in agriculture. These formulations combine nanotechnology and biopesticides derived from plant extracts. The synthesis and characterization of plant extract-based pesticide nanoparticles are found to be more effective than using biopesticides alone. In this review, first, we examine the literature on the use of biopesticides, including both plant extract-based pesticides and biopesticides from microorganisms. Moreover, we review several studies on the combination of plant extract-based pesticides and biopesticides to enhance biopesticide efficacy. Finally, we discuss nanobiopesticides in supporting sustainable and environmentally friendly agriculture by utilizing biopesticides based on nanoparticles. Overall, this review highlights the promising prospects of plant extract-based nanobiopesticides and underscores their potential as effective and sustainable alternatives for pest management in modern agriculture.

Binucleate Rhizoctonia (BNR) fungi are essential for the germination of vanilla seeds. Chemical control of the soil-borne pathogen might adversely affect BNR. The purpose of this study is to determine the effect of Nicotiana tabacum extract biopesticides and Fusarium oxysporum f.sp. vanillae (Fusarium) on vanilla plant nutrient content induced by BNR. Materials and Methods. The research design was completely randomized design with two factors and three replications. The first factor was biopesticide (dosage of 0, 10, 20, and 30 ml/seedling), and the second factor was the application of Fusarium. Results. The increase in the nitrogen, phosphorus, and potassium content of vanilla was affected by biopesticides and Fusarium inoculation. Fusarium inoculation has no significant effect on nitrogen and phosphorus levels but significantly affects potassium levels. The biopesticide dosage is significant for nitrogen, phosphorus, and potassium. The interaction of biopesticides with Fusarium inoculation did not significantly affect the parameters of nitrogen and phosphorus content, but significantly affected potassium content. Conclusion. The application of biopesticides and Fusarium inoculation after induction of BNR can increase nitrogen, phosphorus, and potassium content of vanilla plants.

Full textAbstract:
The global trend towards increased demand for organic food, greener environments, and the integration of biological control agents into pest management strategies has greatly enhanced the need for biopesticides. Biopesticides are made from micro-organisms or other natural substances and are, hence, generally environmentally friendly. However, despite their great potential—and in part due to regulatory challenges—relatively few biopesticides have been registered and commercialised in Nigeria compared to other African countries, such as South Africa and Kenya. Biological active agents are so diverse that applying the same safety standards to all of them is almost impossible. A comparative review of risk assessment processes of Nigeria’s biopesticide regulations with other developing African countries (South Africa and Kenya) and developed regions (the European Union and the United States of America) was conducted. Prolonged field testing, lack of bridged risk assessments, and technical checklists were identified as key factors hampering the research and development of biopesticides in Nigeria. Suitable amendments to the existing regulations guiding biopesticide formulation and utilisation in Nigeria are recommended. Risk assessment matrices for microbial and biochemical pesticides and a scientific/technical checklist have also been developed. It is apparent that harmonisation and data exchange among countries in the region could enhance the advancement of scientific and technical knowledge for sustainable regulation of, and cross-border trade in, biopesticides.

Full textAbstract:
Over the past 50 years, crop protection has relied heavily on synthetic chemical pesticides, but their availability is now declining as a result of new legislation and the evolution of resistance in pest populations. Therefore, alternative pest management tactics are needed. Biopesticides are pest management agents based on living micro-organisms or natural products. They have proven potential for pest management and they are being used across the world. However, they are regulated by systems designed originally for chemical pesticides that have created market entry barriers by imposing burdensome costs on the biopesticide industry. There are also significant technical barriers to making biopesticides more effective. In the European Union, a greater emphasis on Integrated Pest Management (IPM) as part of agricultural policy may lead to innovations in the way that biopesticides are regulated. There are also new opportunities for developing biopesticides in IPM by combining ecological science with post-genomics technologies. The new biopesticide products that will result from this research will bring with them new regulatory and economic challenges that must be addressed through joint working between social and natural scientists, policy makers and industry.

Full textAbstract:
As pesticide abuse becomes increasingly serious worldwide, it is necessary to pay attention to the biopesticide adoption behavior of agricultural producers. It is worth verifying whether agricultural cooperatives, as training organizations sharing the same social network with farmers, can promote the adoption of biopesticides through their technology diffusion function. Therefore, based on survey data of 837 citrus producers in Sichuan Province, China, the IV-probit regression model and a mediation effects model were used to empirically test the impact of technical training on farmers’ adoption of biopesticides in addition to its mechanism, considering the farmers’ perception of technology as the mediation variable. The results show that (a) participation in technical training can significantly enhance the probability of the adoption of biopesticides; (b) farmers’ perceptions of biopesticides’ economic and health benefits play a partial mediating role in the relationship; and (c) technical training has more significant effects on biopesticides adoption behavior for a household with higher-educated household heads, lower household total income, and smaller household size, relative to their counterparts. This study provides evidence for establishing relevant policy to encourage the full adoption of the technical training function of agricultural cooperatives and popularize the use of biopesticides.

Full textAbstract:
Rice (Oryza sativa) is an increasingly popular food in Africa. As much as 30% of yields are lost due to blast disease caused by Magnaporthe oryzae. Several commercial biopesticides of Bacillus subtilis, Trichoderma asperellum, and Serratia sp. strains were evaluated under field conditions for their effects against rice blast and yield at one site in Kenya and three sites in Tanzania in 2020 and 2021. Each biopesticide was applied as a dipping treatment at transplanting, post-transplanting foliar spraying, or both. Using biopesticides not only achieved blast control but also increased grain yield, particularly in low-production regions in Tanzania, with a yield increase of >100%. For higher-production sites with low disease pressure, the yield increase through biopesticides over the untreated control was limited, although significant disease suppression was achieved. Dipping alone was sufficient to suppress disease and improve yield unless disease pressure was high. The differences among the three biopesticides varied with site/year but generally were small. Improved yield using biopesticides is unlikely to result solely from reduced blast development, but also from improved plant development. The present study suggests that these commercial biopesticides should be applied in rice production, particularly in subsistence farming.

Abstract The toxicity, persistence, and non-biodegradability of chemical pesticides have increased calls for the adoption of sustainable and cost-effective pest control measures. Biopesticides present a sustainable alternative to synthetic pesticides. However, the biopesticide utilization in agrarian countries like Nigeria remains low, resulting in increased chemical pesticide utilization. Therefore, this paper seeks to examine the current status, challenges, and prospects of biopesticides in Nigeria. The findings revealed that biopesticide utilization in Nigeria is low due to high costs, poor infrastructure, skilled manpower alongside inconsistent field performance and government policies. The solution to these challenges will significantly boost crop protection, food security, and sustainable agriculture in Nigeria.

Full textAbstract:
The substitution of chemical pesticides by biopesticides is crucial to ensure the quality of agricultural products and to foster environmental sustainability. This study takes the willingness and the behaviors of rice farmers on the application of biopesticides as the research object. The survey questionnaire was designed based on the theory of rational small-scale farmers from three aspects: “individual and family characteristics of farmers”, “cognition of farmers” and “external factors”. The survey was then conducted on 163 rice farmers in seven prefecture-level cities in Jilin Province of China. The logistic model was used to analyze the influencing factors resulting in the deviation of the behaviors of the rice farmers from their initial willingness on the application of biopesticides. The explanatory structure model (ISM) was used to analyze the logical hierarchical relationship among various influencing factors. The results show that: (1) For 45% of the farmers surveyed, there’s a deviation between their willingness and behaviors regarding the application of biopesticides; (2) Among the significant factors leading to the deviation between farmers’ willingness and behaviors concerning the application of biopesticides, the surface-level direct factor is biopesticide awareness. The mid-level indirect factors are agricultural product quality and safety awareness and the deep-level root cause is farmers’ education level. (3) The primary reason for the deviation of the farmers’ behaviors from their willingness is their lack of knowledge about biopesticides and the biopesticides’ incomplete market structure. Based on the comprehensive analysis, it is recommended to improve the professionalization of the farmers, to strengthen the publicity of green production and to accelerate the formulation of the biopesticides market to further promote the usage of biopesticides.

Three bioagents (Trichoderma viride, T. harzianum and Gliocladium virens) and five biopesticides (Achook, Neemgold, Wannis, Spictaf and Neemazal) were evaluated under in vitro and in vivo conditions against Colletotrichum lindemuthianum. All the three antagonistic fungi caused significant inhibition of mycelial growth, maximum being with T. viride (69.21%) followed by T. harzianum (64.20%). Among the biopesticides tested at four concentrations, Wanis applied @ 1000 ?l/ml caused maximum inhibition of 82.12 per cent followed by Spictaf (52.85%). T. viride and Wanis @ 1000 ?l/ml were most effective in reducing the seed borne infection. Integration of bioagents with Bavistin showed that disease can be effectively managed with seed dressing either with Bavistin or biopesticide followed by foliar treatment with fungicide or biopesticide.

Clove oil has the potential to suppress the development of the mosaic virus in patchouli plants, but its effectiveness in the field has not been studied. This study aimed to evaluate the effect of clove nano biopesticide on controlling patchouli mosaic disease. The research was conducted at the Manoko Experimental Garden, Bandung, West Java from March to November 2018. The patchouli used was Patchoulina-2 variety, which originated from the Seed Breeder Garden in Lembang, Bandung. This study was arranged in a Randomized Block Design (RBD), consisting of five treatments and ten replications within each treatment, with one hundred plants in each replication. The results obtained showed that nano biopesticides of citronella, clove, and commercial citronella (Asimbo) were able to reduce the incidence and intensity of mosaic diseases in patchouli plants, showing the efficacy levels of 14.68%, 9.06%, and 5.83%, respectively. The application of citronella and clove biopesticides on Patchoulina-2 every month could increase plant fresh weight, when compared to the plants without treatment. Patchoulina-2 plants treated with nano biopesticides of clove and commercial citronella (Asimbo) showed higher value of fresh weight compared to those treated with citronella nano biopesticide. The clove nano biopesticide can also be developed to control mosaic diseases in patchouli plants.

This study is part of the search for means and methods of sustainable control of Eldana saccharina, the main pest of sugarcane cultivation in Côte d'Ivoire. Despite efforts to control the pest through the selection of resistant varieties, the cultivation of healthy cuttings and the elimination of alternative host plants, the damage, which is already economically significant, continues to increase in the sugarcane-growing areas of Côte d'Ivoire. This study aims to evaluate the effect of two proven biopesticides, ASTOUN 50 EC and NECO 50 EC, on the palatability of E. saccharina larvae and adults. Firstly, different ages of larvae were reared on two nutrient media such as artificial medium and natural medium treated with increasing concentrations of the two biopesticides. 14, 21 and 28 days old larvae were incubated and changes in larval palatability were assessed over a 5-day period. The concentrations of biopesticides tested were 0.5, 1, 2, 4, 8 and 10 ml/l. In addition, the repellent effect of the biopesticides on the adults was assessed using the preferential zone method. The results showed that the biopesticide ASTOUN 50 EC is highly antiappetizing for larvae and repellent for adults of E. saccharina, unlike NECO 50 EC. It also greatly reduced the rate of oviposition in the treated compartments. This biopesticide can be tested in vivo for use against Eldana saccharina.

Essential oils are environment-friendly natural ingredients that can be used as biopesticides. Biopesticide formulation using nutmeg seed oil (Myristica fragrans Houtt) and its application as an inhibitor of lichen growth on rocks. This study aimed to synthesize biopesticides and determine their inhibitory activity on lichen growth on rocks. The biopesticide was synthesized by adding AgNO3 powder directly to the nutmeg seed oil, Tween 80 surfactant, and PEG 400 co-surfactant. The synthesized biopesticide had a dark brown color, indicating that the reduction process was successful, as shown by the formation of absorption at a wavelength of 437 nm. The results of the PSA and SEM-EDX analyses showed that the biopesticide had a particle size of 454.8 nm and was spherical in shape with Ag, C and O contents of 59.07%, 28.94% and 11.99% respectively. The addition of Tween 80 and PEG 400 surfactants resulted in particle sizes of 235 nm and 406.2 nm respectively, and a round and non-uniform shape. Tween 80 affects the synthesis of nutmeg oil biopesticide, that is, it is more stable. The synthetic biopesticide is effective as an anti-lichen on stone surfaces.

The Loss of crop productivity can reach 30-35% if not use pesticide. The other hand, to use of pesticides can be caused environmental problems and human healthy. This research aims to develop biopesticides for pests and plant diseases. It was conducted at the PEM laboratory UIN Suska Riau and on land, from July to November 2015. The sourches were extracts from Andropogon nardus, Annona muricata leaves, Ageratum conyzoides, Piper aduncun fructus, Nicotiana tabacum leaves, Tinospora crispa, Azadirachta indica leaves, Allium sativum and Piper betle leaves. Each the source was macerated in alcohol 50% for 24 hours and then distilled at a temperature of 60 °C until all the alcohol evaporates. The experimental Design was complete random design with 7 treatments (control, 20%, 40%, 60%, 80%, 100% and chemical pesticides as positif control) and 3 replicates. Parameters of the test biopesticides to disease performed in vitro with measure the resistance zones and for mealybugs and Gryllus assimilis in vivo with the pest mortality. Biopesticide test in vitro for the bacteria that causes carrot root rot has not been able to kill microbes. The mortality rate mealybugs begins before 1 hour observation at the treatment biopesticide concentration of 80%, 100% and control positif. Provision of different concentrations of biopesticides, does not the increased mortality of Gryllus assimilis. This shows that the power to kill biopesticide still well below chemical pesticides, but the pest is still alive no appetite as antifeedant effect of the biopesticide. So biopesticide application does not have to kill the target pest. Need follow-up and development of this research and other pests.

Full textAbstract:
Biopesticides are pest and pathogen management agents based on living microorganisms or natural products (botanical origin). Due to their natural origins, they stand out as an environmentally friendly tool, since they quickly decompose and minimize pollution problems produced by synthetic pesticides. However, these products present significant challenges that affect the bioactivities of the active components, due to the degradation of the biomass or bioactive metabolite by factors such as air, light, and temperature. Therefore, in this study, a systematic search of the Scopus database was conducted and scientometric tools were used to evaluate formulation techniques and approaches that seek to improve the bioactivities of natural preparations. The results showed that published research on biopesticides has significantly increased by 71.24% in the last decade (2011–2021). Likewise, the bibliometrics showed, through temporal flow analysis, and in the period from 2010 to 2021, investigations evolved have toward the use of nanotechnology, with the purpose of improving and potentiating the formulations of biopesticides. Consequently, nanotechnology tools can be classified as current strategies of interest that allow the increase and protection of bioefficacy to a greater extent than traditional biopesticide preparations. This review constitutes an important contribution to future research and expands the panorama in relation to biopesticide formulations for the control of agricultural pests.

Full textAbstract:
Pollinators play important roles in providing pollination services, maintaining biodiversity, and boosting crop production. Even though pollinators are essential to the environment and agriculture, their decline has been noted across multiple studies in the recent past. Both natural and anthropogenic factors have contributed to their decline. Much of the focus has been placed on climate change, habitat loss, pests and pathogens, and synthetic pesticides, but relatively little is known about the effects of biopesticides. Biopesticides are biological control agents derived from living organisms and are classified into three groups: microbial, biochemical, and plant-incorporated protectant-based products. Biopesticides are formulated similarly to their synthetic counterparts and are readily available and used within urban and agricultural settings by pest management experts and household residents. The general public and much scientific literature support the prevailing idea that biopesticides are environmentally safe and pollinator friendly in comparison with synthetic versions. However, such generalizations are based on studies with a few key pollinator species and may not be relevant to several other species that provide crop pollination services. Studies focused on native pollinators have shown that some biopesticides have lethal and sublethal effects. Because each biopesticide exhibits varying effects across pollinator species, it could be dangerous to generalize their non-toxicity across taxa and environmental settings. In this article, recent research in this direction is discussed.

Full textAbstract:
Baculovirology has been studied on the African continent for the development of insect virus-based biopesticides and, to a much lesser extent, vaccine production and delivery, since the 1960s. In this review, we focus only on baculoviruses as biopesticides for agricultural pests in Africa. At least 11 species of baculovirus have been discovered or studied on the African continent, some with several distinct isolates, with the objective in most cases being the development of a biopesticide. These include the nucleopolyhedroviruses of Helicoverpa armigera, Cryptophlebia peltastica, Spodoptera exempta, Spodoptera frugiperda, Spodoptera littoralis, and Maruca vitrata, as well as the granuloviruses of Cydia pomonella, Plutella xylostella, Thaumatotibia (Cryptophlebia) leucotreta, Choristoneura occidentalis, and Phthorimaea operculella. Eleven different baculovirus-based biopesticides are recorded as being registered and commercially available on the African continent. Baculoviruses are recorded to have been isolated, researched, utilised in field trials, and/or commercially deployed as biopesticides in at least 13 different African countries. Baculovirus research is ongoing in Africa, and researchers are confident that further novel species and isolates will be discovered, to the benefit of environmentally responsible agricultural pest management, not only in Africa but also elsewhere.

Full textAbstract:
Using qualitative methods, this study assessed the stakeholders and management processes involved in locust outbreaks in China, including factors influencing the use of biopesticides. Study findings show that China has an integrated national locust response protocol, which involves various institutions from all administrative levels of the government. The process is inherently highly complex but efficient, with multisectoral agencies working closely together to prevent and/or manage locust outbreaks. In addition, the process has been successful in combating recent outbreaks, due to dedicated government funding, decisive administrative and technical actions, and the empowerment of local government administration. This is the case with the county level acting as a ‘first-responder’ that is capacitated financially and technically to respond to a locust invasion in their jurisdiction. Additionally, study findings show that despite the availability of biopesticides in local markets, their use is dampened by inadequate information about market availability, negative perceptions by decision makers about their efficacy, and concerns about their costs, as well as limited knowledge of their application techniques. Actions are therefore needed by relevant authorities to enhance stakeholder awareness of biopesticide market availability, efficacy, and field application processes. Future areas of research should focus on modelling the expected impact and cost effectiveness of chemicals vs. biopesticides, thus increasing the evidence base for promoting biopesticide use.

Full textAbstract:
The intensive use of fungicides in controlling soybean rust (SBR), a damaging foliar fungal disease of soybean caused by the obligate fungus Phakopsora pachyrhizi, may have accelerated the insensitivity of P. pachyrhizi populations to fungicides. The objective of this study was to determine the effect of selected biopesticides and their application time on reducing SBR infection. There were differences (P < 0.05) in percent rust reduction values for application times, biopesticide treatments, and their interaction in detached-leaf and whole-plant greenhouse experiments. All application times and nearly all biopesticide treatments reduced (α = 0.05) fungal infection compared with the nonfungicide control. Among the treatments, Bacillus subtilis QST 713 and acibenzolar-S-methyl often reduced fungal sporulation more than the other treatments in detached-leaf and whole-plant greenhouse experiments. The identification of biopesticides effective to P. pachyrhizi may be a valuable alternative or complement to synthetic fungicides and may be useful in integrated pest management programs for SBR control.

Full textAbstract:
Even though pesticides have greatly contributed to boosting agricultural productivity and farmer income over the years, there have been concerns about the safety of some of these pest control products. Besides, there has been a growing demand for good quality and safe food in the recent past – as reflected in the stringent regulations on pesticide residue levels in produce. Biopesticides in comparison with conventional synthetic chemical pesticides are usually less toxic, generally affect only the target pest and closely related organisms, are often effective in relatively small quantities and decompose faster, resulting in lower exposure. Consequently, over the last few years, biopesticides have attracted global attention as a safer pest control strategy for incorporation into Integrated Pest Management (IPM) programmes. Besides, in the last decade, adoption of IPM programmes has significantly enhanced pest management practices and, in some cases, reduced pesticide use, consequently reducing the rise in demand for synthetic chemical pesticides. Also, the development of new synthetic chemical pesticides has declined considerably in the recent past, as regulations have become tighter, with products being withdrawn from the market, resulting in a more limited choice of chemical solutions such that biopesticides have become a more feasible option. Many countries have also increasingly lowered chemical Maximum Residue Levels for agricultural imports which have made it increasingly necessary to explore pest control options which would ensure reduced reliance on the use of synthetic chemical pesticides. In this paper, avenues of addressing challenges to biopesticide research and development are evaluated by seeking the inputs of a wide range of stakeholders, building on a recent international workshop with biopesticides practitioners from across the globe. Prospects for biopesticide application are detailed using a case study on the fall armyworm (Spodoptera frugiperda) in Africa.

Abstract United Nations Organization (UNO) has an agenda for 2030 for Sustainable Agriculture Development as a part of Sustainable Development Goals (SDGs). It gives more attention to food security, regarding not only food availability but also food healthy and a friendly environment. A large amount of pesticide usage in the world increased by 36% or 4.2 million tons in the last two decades 2000-2019. Unfortunately, biopesticides as a part of pesticides that contribute to Integrated Pest Management (IPM) and organic farming share only 1-5% of pesticides on the global market, while it is believed to have a good prospect to be used widely in the future. Due to the hazardous and harmful pesticides, the world countries apply regulations and registration to minimize the bad effect of pesticide use but these are varied in many countries. The difference between synthetic chemical pesticides and the biopesticide mode of action should be considered to have fair regulations. On the global market, there are 1400 biopesticides products. Innovation on biopesticides due to control pests as well as facing environmental and health issues is quite developed, however, it has some constraints in certain aspects to increase the use to support sustainable agriculture development, such as variability in knowledge, different regulations in any country, and lack of distribution at the farmer level. To encourage the wide use of biopesticides can be recommended some strategies for the national government (1) cut off the use of chemical pesticides, (2) develop some research for the near future, such as redesigning cropping systems, enhancing prophylaxis, (3) support the development of public policies and private initiatives for the transition toward pesticide-free agri-food systems, (4) reduce some requirements in biopesticide registration such as toxicological tests, environmental tests, residual tests, and acute oral and dermal tests.

One of the diseases with the greatest economic impact on coffee cultivation worldwide and particularly in Peru is coffee rust (Hemileia vastatrix). The search for sustainable control methods as disease management strategies in coffee cultivation is necessary. The objective of this research was to determine the effectiveness of five biopesticides based on lemon verbena (Cymbopogon citratus) for the control of rust applied in laboratory and field conditions to allow the recovery of coffee (Coffea arabica L. var. typica) in La Convención, Cusco, Peru. Five biopesticides (oil, macerate, infusion, hydrolate and Biol) and four concentrations (0, 15, 20 and 25%) were evaluated. The biopesticides were evaluated under laboratory conditions (light and dark) at different concentrations. The design used was completely randomized in a factorial scheme. The biopesticides were incorporated into the culture medium and inoculated with 400 uredospores of rust, and the germination percentage was evaluated. Under field conditions, the biopesticides at the same concentrations were evaluated for 4 weeks after application. Under these field conditions, the incidence, severity and area under the disease progress curve (AUDPC) of selected plants with a natural degree of infection were evaluated. In the laboratory, the results showed that all biopesticides were effective in reducing the germination of rust uredospores to values <1% of germination in relation to the control, which showed values of 61% and 75% in the light and dark, respectively, independent of the concentration used, with no significant differences between them. In the field, 25% oil promoted the best response with values <1% and 0% incidence and severity, respectively, in the first two weeks after application. The AUDPC for this same treatment showed values of 7 in relation to 1595 of the control. Cymbopogon citratus oil is an excellent biopesticide that can be used to control coffee rust.

Green chemistry and sustainableagriculture are inherentlyintertwined; farmers need greenchemists to make safe agriculturalchemical inputs. Green chemistsneed farmers practicing sustainableagriculture to provide truly ―green‖bio-based raw materials to processinto new products.Green Chemistry connectswith sustainable agricultureas a consumer of agriculturalproducts, as a source forremediation technologies,and as a producer of inputs.In very general terms, according to the US EPA, biopesticides are pesticides derived fromnatural materials such as animals, plants, bacteria, and minerals. The two key categoriesfocused on in this report include biochemical and microbial pesticides (reviewing the third category of biopesticides, transgenic crops, was outside the scope of this report). Thesubcategories of biochemical pesticides introduced in this report include insect pheromones,plant extracts and oils, plant growth regulators and insect growth regulators. Microbialpesticide subcategories discussed include bacteria, virus, fungus, and other less commonmicroorganisms. Biopesticide solutions often require the grower to learn new application techniques and new ways of thinking about pest management. As noted, biopesticides are often highly specific and have very precise modes of action. This specificity can mean that workers can enter fields quickly after use, thus cutting wait times and offering more flexibility to the user. Specificity also means, however, that growers may need to purchase several different kinds of product to meet their pest management needs; this is a potential cost concern for growers. Biopesticides also require new skills and understanding of pests, their life cycles and how to use biopesticides to intercede effectively. This is both a challenge but also an opportunity for expanding a new category of skilled labor in the farm sector.

The application of ecological plant protection products against diseases, pests, and weeds is relevant for modern science-provided crop production. Much attention is paid to this problem in the European Union, where the use of pesticides is strictly adjusted by the European Food Safety Authority. Great hopes are pinned on biological plant protection products. However, among the thousands of biological products included in the BioPesticide DataBase, only a small number are authorized for use in agriculture. The requirements for the use of biological protectants in organic farming are even more stringent, regulating not only the properties of the product but also the crops in which they can be used. The aim of the work was to present the main requirements for the safety of biopesticides in the EU countries and to give an overview of biopesticides authorized for use in traditional and organic farming using Germany as an example. Methods. Analysis of EU documents on the requirements for registration of active substances in biological products for plant protection, biopesticide databases, and the list of biopesticides approved for use in general and organic farming in Germany. Results. According to the EU requirements for biopesticide safety, registration of biological plant protection products based on bacteria, fungi, and viruses, individual microbial cellular components or metabolites, as well as insect predators, pheromones, and plant-origin substances is allowed. Among the biopesticides with bactericidal and fungicidal effects registered in Germany, the preparations based on microbial antagonizing plant pathogens are prevalent, as well as preparations elaborated on the fungus Aureobasidium pullulans, Trichoderma asperellum, Verticillium albo-atrum, Coniothyrium minitans, bacteria Pseudomonas chlororaphis, Bacillus amyloliquefaciens, and also the preventive drug Cerevisan based on the cell walls of Saccharomyces cerevisiae. The following bioformulations based on Bacillus thuringiensis, Beauveria bassiana, Cydia pomonella Granulovirus, avermectin antibiotic Abamectine A, herbal products Azadirachtin A and Piretrin, and Maltodextrin are registered as insecticides. A bioformulation based on Bacillus firmus is authorized for use as a nematocide. Conclusions. Registration of biological plant protection products in Germany is carried out in accordance with the EU requirements for the safety of biopesticides. The list includes preparations based on antagonistic microorganisms, predatory microorganisms, microbial metabolites with antibiotic activity, substances for stimulation in plants nonspecific resistance to infectious agents. The fungicidal products are the widest represented. The number of products to control bacterial and nematode infections as well as the bioinsecticides spectrum is very limited. These are the well promising areas for further research and development of biological products.

Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, is the most serious threat to the global citrus industry, and its management has mainly depended on the application of chemical insecticides. The use of biopesticides can play an important role in regulating this pest. In a first test, two separate experiments were conducted in two different municipalities (Apulo and Jerusalen, Cundinamarca, Colombia) to evaluate the effect of foliar Beauveria bassiana and imidacloprid sprays on ACP populations in 2015 and 2016, respectively. In a second test, two separate tests were carried out in commercial Tahiti lime orchards to evaluate the efficacy of three different commercial biopesticides (Beauveria bassiana and extracts of Sophora sp. and garlic-chili pepper). In test 1, imidacloprid-treated trees showed a reduction (60% and 80%) in cumulative ACP adults in 2016. ACP cumulative nymphs were also diminished by foliar imidacloprid and B. bassiana application, between 40% and 65% in 2015 and 2016, respectively. ACP cumulative eggs showed lower individuals in imidacloprid-treated flushes at 3 and 4 weeks after treatment 9 (WAT) in 2016. In test 2, the results obtained showed ACP adults and eggs unaffected by biopesticide treatments; nymphs were reduced 50% to 75% in trees treated with the three biopesticides in comparison with control trees. All three biopesticides tested can be considered useful tools in integrated pest management (IPM) programs for ACP, since these products reduced immature ACP individuals between 50% and 75% under field conditions.

Full textAbstract:
Cultivation of plants by utilizing a small area can be developed, especially during a pandemic, among others, by using a hydroponic system. Vegetable yields (pakcoy, lettuce) do not always have good quality due to pest attacks, including in the hydroponic system, resulting in a decrease in both quantity and quality, which affects the income and turnover of this micro-enterprise (UMKM). The objectives of this service are 1) provide knowledge and skills in making biopesticides based on refugia plants or organic pesticides (“pestisida nabati”) in order to improve the quality and quantity of production, and 2) The practice of “pestisida nabati” application for hydroponic cultivation. Service activities are carried out with the following methods: providing material and discussion, making vegetable pesticides/biopesticides, and applying “pestisida nabati” in hydroponic cultivation in Micro Business Groups (UMKM "Ini Hydroponics." Accordingly, 12 participants in the training for making biopesticides and their application were practitioners, partners, and students interested in developing hydroponics. The training on making biopesticides with the essential ingredients of mischievous (Cosmos caudatus) and neem leaves (Azadirachta indica) has resulted in a solution of vegetable pesticides ready to be applied in hydroponic cultivation. The spraying application is carried out on the first day after the biopesticide is made and a week later. Based on observations of the quality of lettuce harvested a week after spraying, the product obtained showed a lower pest attack than before.

Full textAbstract:
Fewer postharvest technologies are available for use on organic than conventional fruits and vegetables. Even though biopesticides are perceived as likely candidates for postharvest use on organic produce, only some biopesticides will be approved as organic compounds for various reasons. An example is the definition of a biopesticide used by regulatory agencies such as the EPA which includes compounds that will not be considered organically acceptable. Fortunately, there are other existing or new technologies that could be acceptable on organic fruits and vegetables. Some examples are hot water immersion treatment or a hot water rinsing and brushing, new innovative controlled atmosphere techniques, alternative sprout control agents, naturally occurring volatiles and biofumigants. More research is needed on each of these technologies, both singly and in combination with each other.

Full textAbstract:
This article explores the role of bioinputs in Brazilian agriindustry, a sector that is increasingly adopting biological inputs to improve crop protection and productivity. The major class of bioinputs, biopesticides, are derived from natural sources such as fungi, bacteria, nematodes, insects and viruses, and offer several advantages over conventional pesticides, such as lower environmental and health impacts, higher specificity and compatibility with integrated pest management. The article presents economic data, registration statistics and application examples of different types of biopesticides in Brazil. It also discusses the challenges and opportunities for biopesticide development and adoption in Brazil, taking into account the legislative framework, the research and development programs, the quality standards and integration with conventional inputs. The article concludes by emphasizing the importance of bioinputs for tropical agriculture and suggesting some areas for future research.

Full textAbstract:
The development and implementation of safe natural alternatives to synthetic pesticides are urgent needs that will provide ecological solutions for the control of plant diseases, bacteria, viruses, nematodes, pests, and weeds to ensure the economic stability of farmers and food security, as well as protection of the environment and human health. Unambiguously, production of botanical pesticides will allow for the sustainable and efficient use of natural resources and finally decrease the use of chemical inputs and burden. This is further underlined by the strict regulations on pesticide residues in agricultural products and is in harmony with the Farm to Fork strategy, which aims to reduce pesticide use by 50% by 2030. Thus, the present work aims to compile the scientific knowledge of the last 5 years (2017–February 2023) regarding the Mediterranean plants that present biopesticidal effects. The literature review revealed 40 families of Mediterranean plants with at least one species that have been investigated as potential biopesticides. However, only six families had the highest number of species, and they were reviewed comprehensively in this study. Following a systematic approach, the extraction methods, chemical composition, biopesticidal activity, and commonly used assays for evaluating the antimicrobial, pesticidal, repellant, and herbicidal activity of plant extracts, as well as the toxicological and safety aspects of biopesticide formulation, are discussed in detail. Finally, the aspects that have not yet been investigated or are under-investigated and future perspectives are highlighted.

The use of unsustainable levels of plant protection chemicals and fertilizershas resulted in a steady decline in soil quality and crop productivity the world over. To combat this decline, agricultural practices must evolve to meet the growing global demand for food without irreversibly damaging the world’s natural resources.Biopesticides have tremendous potential to bring sustainability to agriculture and environmental safety.This article is part of a larger study conducted in India by the authors at theUniversité de Montréal with the support of Mitacs and Earth Alive Clean Technologies. In this research, farmers, manufacturers or suppliers of biopesticides, and R&D scientistswere interviewed, and their responses demonstratethe advantages of applyingmicrobial biopesticidesto field crops. Participants reported a15-30% increase in yields and crop production after the application ofbiopesticides, with better quality and quantity of fruits, grains, and tubers with a longer shelf life. Moreover, while the risk of croploss is high (60-70%) with chemicallygrown crops, this risk is reduced to 33% on average when crops are grown using biopesticides. The risk of crop loss is thus considerably reducedby the use ofbiopesticides.Yet, despite their positive impact on the health of humans, soil,ecosystems, andfriendly invertebrates,biopesticides face significant challenges and competition vis-à-vis synthetic pesticides for a variety of reasons. The development of biopesticides must overcome the problems of improper formulations, short shelf life, delayed action, and high market costs, as well as a variety oflegal/registration issues.

Young farmer group Putra Mandiri Sejahtera (PMS) in Sambirejo Village, Selomartani, Kalasan, is actively involved in organic farming. Their vision is to advance agriculture through extension programs, training, mentoring, and cultivating food crops by implementing agricultural innovation technology. The challenges they often face are larval pests that attack many crops, which are difficult to overcome. Efforts that can be made are providing techniques for the identification of larval pests and their biological agent, preparing fungal biopesticides, and applying control methods by technical culture. Stages in these activities include (1) an extension program on the identification of pests and their biological agent, (2) training on fungal biopesticide preparation, and (3) mentoring and monitoring of the farmers’ activities by applying pre-and post-test. The community service results demonstrated that the extension program on larval pest identification had improved the farmers’ understanding by 72.22% and increased their willingness to learn further. The following training on fungal biopesticide preparation showed that the farmers’ skills improved by 95.24%, despite the fact that the remaining 4.76% of the farmers required more training to achieve more confidence. In addition, it was also found that 57.14% of the farmers stated they had mastered the biopesticide preparation, while the remaining 42.85% of the farmers required further training and mentoring. The output of this extension program was two types of fungal biopesticides, Beauveria sp. and Metarrhizium sp., produced by the young farmer group Putra Mandiri Sejahtera (PMS).

Full textAbstract:
Plant growth regulators (PGRs) are often used in crop production for specific niche market needs. PGRs are frequently viewed as secondary business opportunities by the private sector, especially when compared to herbicide, insecticide, and/or fungicide markets. Nonetheless, PGRs are regulated by the U.S. Environmental Protection Agency (USEPA), and the additional cost of regulatory compliance as part of commercial development is significant. Of the two broad classes of pesticides regulated by the USEPA, conventional chemicals and biological pesticides (or biopesticides), many PGRs belong to the biopesticide class, specifically the biochemical category. Because of USEPA's responsibility to assure that any pesticide used in commerce will not result in unreasonable adverse effects to humans or the environment, specific data requirements have been established for product registration. Registrants must address each requirement, either by submitting relevant data or a request to waive the requirement, prior to receiving a federal registration. For biochemical PGRs, the acceptability of data or waiver requests, as well as any proposed label uses, are reviewed by the Biopesticides and Pollution Prevention Division (BPPD). The BPPD was formed in 1994 to facilitate the development of biopesticide products. Given the time and expense associated with PGR product development and commercialization, registrants should work closely with the USEPA and other stakeholders to help ensure successful product development.

Abstract . Some biopolymer materials can be used as filler to increase the slow release capacity of the active component. Technology modification of biopesticide production processes to increase its slow release capacity can use sodium alginate, maltodextrin and CMC (Carboxy Methyl Celluose). The purpose of this research activity was to modify the formulation of the use of several types and concentrations of biopolymers and analyze the characteristics of slow release in citronella oil-based biopesticides. The research method was carried out in stages including: produced nano emulsions, added biopolymer matrices and analyzed their characteristics as well as the slow release capacity of biopesticides with citronella oil ingredients. The biopolymer concentration ranges added are 1, 2 and 5%. While the addition of CMC was done using concentrations of 0.5, 1 and 2%. Based on the results of the study showed that the maximum addition of maltodextrin was 2% and the maximum CMC addition was 1%. Whereas addition of Sodium alginate results in unstable biopesticide products and separate solutions. The size of the droplet has a range between 131.8 to 177.1 nm. Based on the results of the analysis of citronella components and dl-Limonene experiencing fluctuating releases during 0 to 12 days. The next research activity requires optimization of activities before implementation at the field level.

Full textAbstract:
During the years 2020 and 2021, the effects of various biopesticides and the egg parasitoid Trichogramma chilonis on the okra shoot and fruit borer were investigated in open fields. All interventions outperformed over the untreated control. The entomopathogenic bacterium Bacillus thuringiensis was the most promising biopesticide tested, with the lowest shoot (5.49% and 6.87% in 2020 and 2021, respectively) and fruit damage (4.95% and 5.65% in 2020 and 2021, respectively), followed by the entomopathogenic fungi Beauveria bassiana (7.08%, 8.04% shoot damage and 6.78% and 6.73% fruit damage during 2020 and 2021, respectively). Interestingly, all biopesticides evaluated were shown to be safe for the polyphagous predators occurring in the okra habitat, such as the ladybird beetles Menochilus sexmaculatus and Micraspis discolour and the spiders Marpissa spp. and Oxyopes lineatipes. However, emamectin benzoate 5% SG was the most effective treatment in terms of minimizing okra shoot and fruit damage, resulting in a maximum percent reduction over control (PROC) (85.54 and 80.90 against shoot damage and 76.60 and 71.33 against fruit damage during 2020 and 2021, respectively). Each treatment's economics were also analysed. The experimental plots treated with emamectin benzoate had the highest cost:benefit ratio (1:11.16), while B. thuringiensis had the highest (1:7.06) among the biopesticide / parasitoid releasing plots.

Integrating biological-based fungicides into conventional spray programs may help with fungicide resistance management. However, little is known about how to best integrate these products while still maintaining maximum disease control. Programs with as few as one synthetic fungicide or as many as three synthetic fungicides added to a biopesticide-based rotation during the bloom period of Vitis vinifera had significantly better disease control than a biopesticide-only-based program. When integrated with different timings of fruit-zone leaf removal, specific combinations of biopesticide programs and fruit-zone leaf removal enhanced the efficacy of that program to be on par with disease control seen in a program entirely based on synthetic fungicides. This suggests that when designing a fungicide program using biopesticides as a base, the addition of a synthetic fungicide during the window of ontogenic susceptibility in clusters and the adoption of cultural practices such as leaf removal can significantly improve the efficacy of that program.
