“…This is compounded by the fact that biopesticides containing live organisms have a short shelf life, increasing stockist risk if demand is low. Srinvasan et al ., 33 identify availability and access to biopesticides as major constraints to greater adoption in Africa (and Asia). However, there are likely also other reasons for the low demand, so simply getting agro‐dealers to stock more biopesticides might have little impact on sales.…”

Background: Although Kenya has a relatively high number of registered biopesticide products, little is known about biopesticide use by smallholders. This paper documents farmers' current use and perception of chemical pesticides and biopesticides, their willingness to pay for biopesticides, and the key challenges to biopesticide uptake. Results: A survey found that chemical pesticides are used widely by smallholders despite awareness of the risks to human health and the environment. Almost half of respondents showed awareness of biopesticides, but current use in the survey localities was low (10%). Key reasons for the low use of biopesticides by smallholders in this study are: perceptions of effectiveness, primarily speed of action and spectrum of activity, availability and affordability. Smallholders who used biopesticides cited effectiveness, recommendation by advisory services and perception of safety as key reasons for their choice. Although farmers viewed both pesticides and biopesticides as costly, they invested in the former due to their perceived effectiveness. Average willingness to pay, above current chemical pesticide expenditures per cropping season was 9.6% (US$5.7). Willingness to pay differed significantly between counties, and was higher among farmers with more education or greater awareness of the health risks associated with pesticide use. Conclusion: This study confirms the low use of biopesticide products in the survey areas, alongside high use of conventional chemical pesticides. In order to promote greater uptake of biopesticides, addressing farmers' awareness and their perceptions of effectiveness is important, as well as increasing the knowledge of those providing advice and ensuring registered products are available locally at competitive prices.

“…Therefore the environmental effect should be considered when planning an integrated pest management strategy based on the application of entomopathogenic fungi such as B. bassiana and M. anisopliae (McGuire & Northfield, 2020). Both entomopathogenic fungi have high pathogenicity against leafminers of pea bean (Migiro, Maniania, Chabi-Olaye, & Vandenberg, 2010), common bean, Phaseolus vulgaris (Gathage et al, 2016), and major pests of vegetable legumes and brassicas (Srinivasan, Sevgan, Ekesi, & Tamò, 2019).…”

An increasing studies related with the detrimental effects of agrochemicals suggested the advantage of biofertilizers and biopesticides uses to support the sustainable farming system. This study aimed to evaluate the response of shallot 'Lembah Palu' with the application of arbuscular mycorrhizae (AM) and Beauveria bassiana (Bb) under organic farming system. A split-plot experiment was designed to combine Bb at two intervals (every 5 and 10 days) and AM with three rates (0; 5; and 10 g per plant). Leafminer population and infestation, root colonization, root biomass, and shallot yield were observed. Application of the AM and Bb affected shallot production and leafminer infestation, independently. Mycorrhizae application increased the root biomass and yield of shallot but gave negligible effects on population and leafminer attack. The shallot production with no mycorrhizae was significantly lower compared to both mycorrhizae application rates of 5 g and 10 g. The application of B. bassiana every 5 days was more effective in suppressing the population and infestation of leafminers compared to that every 10 day-treatment. The study points out the positive contribution of the mycorrhizae and B. bassiana in the shallot cultivation and supports the implementation of the organic farming system.

“…Since cabbage is more intensively cultivated, it resulted in higher rate of pest infestation, which hinders its total production and consumption 2 . Some of the major defoliating caterpillars that cause signi cant damage to the crucifers are Pieris brassicae (L.)

Cabbage is considered as one of the most commonly found vegetables and it has been cultivated in large areas throughout the year. As it is mostly grown in large areas, higher rate of pest infestation likely to occur, which hinder its total production and consumption. However, continuous use of synthetic pesticides in agricultural pest management often leads to various negative impacts such as development of resistance by the pest, adverse effect on non target organisms and hazardous effect on environmemt. These drawbacks led to an alternative approaches for control of crucifer pests that are cost effective, biodegradable, low toxic effect on non-target organisms and eco-friendly. This review brings together all the information of different biological practices for management of crucifer pests and list of botanical insecticides and entomopathogenic microbes that are being reported. This will help in establishing the knowledge of limited studies on pest management using different biological control methods to more challenging research and conveys the importance of pest management system for taking research forward.
