Abstract:
The investigation on the evaluation of insecticides against jassid and fruit borer was conducted in the research farm of Uttar Banga Krishi Viswavidyalaya, Pundibrar, Cooch Behar, and West Bengal, India during pre-khairf season of 2015-2016. Out of six insecticides evaluated, except neem all other insecticides performed well at higher levels in suppression of pest infestation and percent reduction of damage. However, Imidacloprid (25g a.i/ha), Acephate (500 g a.i/ha), and Agniastra an organic insecticide (25 ml/L) proved better with respect to pest suppression as well as the yield of marketable okra. The highest yield was recorded from the Imidacloprid (25g a.i/ha) sprayed plots followed by Agniastra (Agniastra 25ml/L) i.e. 12.72 t/ha and 12.21 t/ha respectively. Although, Imidacloprid (25g a.i/ha), was found superior to all insecticides in all aspects. However, Agniastra (Agniastra 25ml/L) may be preferred considering, the health and production of chemical-free export produce sacrificing a little yield.
