The experiment was conducted on bio-efficacy of Biopesticides and certain chemical insecticides against mustard aphid (Lipaphis erysimi Kalt.) at research farm Department of Entomology, SHIATS Allahabad during Rabi season of 2012-2013. Bio-efficacy of Biopesticides and certain chemical insecticides against mustard aphid (Lipaphis erysimi Kalt.) on mustard revealed that treatments of Dimethoate 30 EC followed by spraying of Malathion 50 EC and Neem oil (0.5%) were found more effective for control of Lipaphis erysimi Kalt., respectively. Whereas, the descending order of treatments were Neem oil > NSKE > Tobacco Leaf extract > Bacillus thuringiensis > Beauveria bassiana > Metarhizium anisopliae. The least effective treatment was Verticillium lecanii. Maximum infestation was recorded in control.

Abstract


The experiment was conducted on bio-efficacy of Biopesticides and certain chemical insecticides against mustard aphid (Lipaphis erysimi Kalt.) at research farm Department of Entomology, SHIATS Allahabad during Rabi season of 2012-2013. Bio-efficacy of Biopesticides and certain chemical insecticides against mustard aphid (Lipaphis erysimi Kalt.) on mustard revealed that treatments of Dimethoate 30 EC followed by spraying of Malathion 50 EC and Neem oil (0.5%) were found more effective for control of Lipaphis erysimi Kalt., respectively. Whereas, the descending order of treatments were Neem oil > NSKE > Tobacco Leaf extract > Bacillus thuringiensis > Beauveria bassiana > Metarhizium anisopliae. The least effective treatment was Verticillium lecanii. Maximum infestation was recorded in control.
