ABSTRACT

A field experiment was conducted at Regional Research Station (Terai Zone), Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar (India) during the summer season of 2016 to determine the utility and economics of biointensive pest management modules against major insect-pests of cowpea in comparison to conventional pesticide based pest management modules. The pesticide based management modules proved better as compared to the biopesticide based modules in managing the attack of sucking pests and pod borer of cowpea. The pesticide based IPM-II module resulted in the highest per cent reduction of pod borer population (91.17%) and the highest pod yield (9.85 t/ha). The IPM and biopesticide based management modules resulted in poor cost-benefit ratio. However, the biopesticides and new ecofriendly molecule flubendiamide were found to have less hazardous effect on the population of natural enemies as compared to the pesticide based treatments; thus this approach is augmenting the natural control of pests.
