SK Dotasara, N Agrawal, Narendra Singh and Dinesh Swami

A field experiment on cauliflower var. Pusa Snowball-16 was conducted during Rabi season of year2014-15 at CSAUA&T, Kanpur. Among the various insecticides evaluated against the mustard aphid, Lipaphis erysimi Kalt, imidacloprid 17.8 SL @ 0.2 g/litre showed highest reduction. Imidacloprid 17.8 SL @ 0.2 g/litre reduce the 87.53 % incidence of mustard aphid followed by fipronil 5 SC @ 1.0 ml/litre 83.56 % reduction at 7 days after Ist spray, respectively. Similarly same trend was noticed after 15 days of spraying in which both the chemicals registered 83.86 % and 78.90 %. The experiment was repeated after 15 days to check the aphid population and it was observed that imidacloprid 17.8 SL @ 0.2 g/litre was found best followed by fipronil 5 SC @ 1.0 ml/litre and neem oil 2 % @ 2.0 ml/litre, when the data was recorded after 7 and 15 DAS.
