Resumen

Oil droplets containing surfactants and pesticides are expected to spread on a water surface, under the Marangoni effect, depending on the surfactant. Pesticides are transported into water through this phenomenon. A high-speed video camera was used to measure the movement of Marangoni ridges. Gas chromatography with an electron capture detector was used to analyze the concentration of the pesticide in water at different times. Oil droplets containing the surfactant and pesticide spread quickly on the water surface by Marangoni flow, forming an oil film and promoting emulsification of the oil–w

Resumen

There is interest in incorporating nanoemulsions into certain foods and beverages, including dips, dressings, drinks, spreads, and sauces, due to their potentially beneficial attributes. In particular, excipient nanoemulsions can enhance the bioavailability of nutraceuticals in fruit- and vegetable-containing products consumed with them. There is, however, potential for them to also raise the bioavailability of undesirable substances found in these products, such as pesticides. In this research, we studied the impact of excipient nanoemulsions on the bioaccessibility of pesticide-treated tomat

Palm oil (Elaeis guineensis) is a tropical plant that can be attacked by various pests, start from nurseries to plantations, so it is necessary to eradicate pests. Generally, the pests is eradicated by applying pesticides using fogging machines brought down by farmers so that they are ineffective in reaching high plants, and hot smoke from fogging machines can damage oil palm leaves. This study aims to design a tool that can optimize the application of pesticide fog to oil palm plants at a certain height.

Resumen

Despite the abundance of palm-based residues generated, the by-products from thermochemical processing such as bio-oil may create value-added products to the palm industry. The palm-based derived bio-oil contains high aromatic compounds, which are active ingredients in the bio-pesticides formulation. Therefore, this study investigated the formulation of the bio-pesticide from this bio-oil and determines their effect on insect-pest in oil palm such as Metisa plana walker bagworm.

Abstract Agriculture is an important occupation in Malaysia that generates a major portion of the national revenue. Similar to the rest of the world, pesticides are used to boost agricultural production in Malaysian farms. However, chemical pesticides are associated with human health hazard and are not environment-friendly as they persist in nature for long periods of time. Therefore, pesticide use should be reduced and farmers should be trained on correct and/or alternative ways of pesticide use.

Resumen

Origanum majorana is a medicinal and aromatic plant that belongs to the Lamiaceae family. It is cultivated in several parts of the world and, due to its splendid aroma and taste, is widely used for culinary purposes and in perfumes. The essential oil of the plant, to which is attributed its aroma, contains many secondary metabolites with valuable biological activity. One of them is the pesticide activity, which has attracted much interest. Given the necessity of replacing synthetic pesticides, essential oils are studied in an attempt to find naturally derived products. Thus, the aim of this re

Resumen

The bunch moth, Tirathaba mundella is one of the leading pests in oil palm estates established on peatland. Severely infested male inflorescences usually would fail reaching anthesis. Reduction in the number of inflorescences at anthesis stage would suggest less food source and breeding ground for oil palm pollinating weevils, Elaeidobius kamerunicus, thus, affecting the fruiting percentage of oil palm and its yield. Despite to be less detrimental to the environment, biopesticide usages in the field is losing favour due to its slower rate of kill compared with conventional chemical pesticides,

The essential oil of Cymbopogon martinii was tested for its potency as a botanical pesticide to protect stored wheat (Triticum aestivum) and gram (garbanzo bean, Cicer arietinum) from insect infestation. The C. martinii oil was potent as a fumigant in stored gram. The oil was an effective repellent against the beetles Callosobruchus chinensis and Tribolium castaneum. Geraniol, the major component of the oil, was not as effective as the oil itself. C. martinii oil significantly affected oviposition, adult development, and mortality of C. chinensis in cow peas (Vigna unguiculata). The C. martini

Resumen

The debate on the use of pesticides is very current in the public media when it comes to topics such as organic farming, bee mortality, and the use of glyphosate. The broad range of pesticide applications and their potential environmental impact makes pesticides an interesting topic for science education in general and for chemistry teaching in particular. This is particularly true when conventional pesticide use is contrasted with current chemistry research efforts to develop alternatives based on the ideas of green chemistry.

Pesticide droplet deposition determines the efficacy of pesticide solution and is a critical process in pesticide application. Adding spray adjuvants can improve droplet deposition to a certain extent, but there are currently many types of adjuvants with different properties. The improper selection or unreasonable use of adjuvants may be counterproductive, increasing the loss of pesticides or causing crop damage. In this study, the adjuvants methylated plant oil (Beidatong), alkoxy modified polytrisiloxane (Silwet408), hyperbranched fatty alcohol ether modified polymer (ND500), and polymers ad

Multi-residue methodologies necessitate a tailored and precise approach across all areas of analysis. Analyte extraction must be closely correlated with the sample matrix to ensure the optimal recovery for the maximal array of analytes, thereby fulfilling all legal requirements concerning analytical determination. Although the QuEChERS method offers undeniable advantages, it proves unsuitable for pesticide residue determination in matrices with high oil contents.
