Abstract:

Botanical Pesticides (BPs) have been cited and are used as alternative to synthetic pesticides in agricultural systems worldwide. The BPs are believed to be safe to the environment and are used in pest control to avoid pesticidal pollution, which is a universal problem. In this review, authors provide comprehensive information on the use of BPs in management of common bean pests in Africa. This piece of literature is useful due to major negative side effects to the environment as well as human health arising from synthetic chemicals. It is due to this reason that the authors composed this revi

Bruchid beetles (Coleoptera: Bruchidae) are seed-eating insects; most of their species’ feed on legumes. Bean crops around the world (especially Phaseolus vulgaris) are favorably attacked by the common bean weevil (Acanthoscelides obtectus (Say)) and Mexican bean weevil (Zabrotes subfasciatus (Boheman). A. obtectus and Z. subfasciatus are the main pests of beans. These pests are present in almost all bean-producing localities of Tanzania.

Abstract:

In Uganda, the common bean (Phaseolus vulgaris) is often infested by a complex of insect pests, but bean flies, aphids, bean leaf beetles, and flower thrips are the most important. Whereas yield losses due to these pests have been established, there is limited information on their population dynamics at different stages of crop growth and their effect on yield and yield components. In order to describe the population dynamics of selected common bean pests at various phases of bean crop growth, and their impact on yield and yield components, a study was carried out in Uganda during the 2016 sec

Abstract:

Weeds and insect pests are among the serious constraints in common bean production in most rural communities. A survey of 169 smallholder farmers was conducted in two common bean-growing districts in northern Tanzania. The aim was to assess farmers’ knowledge, perceptions, current management practices and challenges in order to develop sustainable weed and insect pest management strategies. The results revealed that 83% of farmers perceived insect pests as the major constraint in common bean production, while 73% reported weeds as the main drawback.

Abstract:

Common bean (Phaseolus vulgaris) is an important food and cash crop in many countries. Bean crop yields in sub-Saharan Africa are on average 50% lower than the global average, which is largely due to severe problems with pests and diseases as well as poor soil fertility exacerbated by low-input smallholder production systems. Recent on-farm research in eastern Africa has shown that commonly available plants with pesticidal properties can successfully manage arthropod pests. However, reducing common bean yield gaps still requires further sustainable solutions to other crop provisioning services

Common beans (Phaseolus vulgaris L.) are considered a socially and economically important crop, with the biggest growers in India, Myanmar, and Brazil. Traditionally, common beans are also grown in most parts of Europe, including Latvia, where cultivation areas have remained relatively constant since the middle of the last century. This is explained by the plant’s higher thermal requirements compared to peas and faba beans more widely grown here.

Abstract:

In order to identify the principal constraints and trends for common bean production and commercialization and the priorities for future common bean research in Africa, Latin America and the Caribbean (LAC), a priority setting process was developed at the International Center for Tropical Agriculture (CIAT). The results suggested that the principal research included breeding and selecting for several traits, such as drought tolerance and water use efficiency, improved yields, and consumer acceptance (improved cooking time and desired texture after cooking). Additionally, the results of the pri

Abstract:

Elicitors are biofactors that induce resistance in plants against different insect pests. This in vitro study evaluated the impact of a novel elicitor protein PeBC1, extracted from a necrotrophic fungus Botrytis cinerea, on the development and fecundity parameters of green peach aphid (Myzus persicae) on common beans (Phaseolus vulgaris L.). Three different concentrations of PeBC1 elicitor (i.e., 33.56, 25.43, 19.33 µg mL−1) were applied at three different temperature regimes (i.e., 18, 21, and 25 °C). Elicitor treatments were applied topically on the bean plants at 3-leaf stage and newly emer

Abstract:

Bean leaf beetles (Ootheca spp.) (Insecta: Coleoptera: Chrysomelidae) are one of Africa’s most destructive pests of common bean and other leguminous crops. The beetles are widely distributed in Africa where they are estimated to cause annual crop yield losses of 116,400 tons of crop yields in sub-Saharan Africa. Despite their importance, little is known about the distribution, relative abundance and damage caused by bean leaf beetles in Uganda. As a result, the development of effective management methods has been hampered. We conducted surveys in six key Ugandan agro-ecological zones to determ

Abstract:

Common bean (Phaseolus vulgaris L.) is the primary source of protein and nutrients in the majority of households in sub-Saharan Africa. However, pests and viral diseases are key drivers in the reduction of bean production. To date, the majority of viruses reported in beans have been RNA viruses. In this study, we carried out a viral metagenomic analysis on virus symptomatic bean plants. Our virus detection pipeline identified three viral fragments of the double-stranded DNA virus Pelargonium vein banding virus (PVBV) (family, Caulimoviridae, genus Badnavirus).

Long cooking time, and high phytic acid and polyphenols that influence bioavailable iron also limit the health benefits.

The common bean is an important food and cash crop in Eastern, Central and Southern Africa. It provides food for more than 100 million people and is a critical source of income for rural households. Common bean yields, however, have declined in the last ten years. This decline is the result of poor soil fertility and nutrient depletion as well as high incidences of insect pests, key among them being the bean stem maggot (BSM). To address soil nutrient depletion and the accompanying declining agricultural productivity, integrated soil fertility management (ISFM) has been adapted as a framework

This paper evaluated farmers’ knowledge, control strategies, and challenges in managing BLBs. Over 87% of the farmers in Arua and Lira could identify BLBs by local names, compared to less than 45% in Hoima and Lwengo. Less than 8% of the farmers in all districts were aware that BLBs ov
