Abstract
The field experiment was carried out in the pre-kharif season of 2013 at Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India to evaluate the efficacy of different bio-pesticides against sucking pests of okra. The experiment was laid out in randomized complete block design with three replications for each treatment. The treatments viz. annonin 1% EC, karanjin 2% EC, Azadirachtin 1% EC, Metarrhizium anisopliae, Verticillium lecanii , Beauveria bassiana , Bacillus thuringiensis var Kurstaki, spinosad 45 % SC and imidacloprid 17.8% SL were applied at 15 days interval starting from seedling stage when whitefly and jassid infestation started. Results revealed that the overall best performance of insecticides against whitefly was recorded in imidacloprid treated plots with lowest mean population of whitefly (3.91 whitefly/15 leaves) followed by karanjin (4.16 whitefly/15 leaves) and azadirachtin (5.16 whitefly/15 leaves while the order of efficacy aginst jassid were imidacloprid (15.27 jassids/15 leaves) > karanjin (33.91jassids/15leaves)>azadirachtin(40.38jassids/15leaves). Effectiveness of test insecticides on the yield of okra wasspinosad>Bt>B. bassiana>azadirachtin>imidacloprid>annonin>karanjin>M. anisopliae.
