Effect of some insecticides on aphid population in bell pepper (Capsicum annuum L.)

Abstract

The study was carried out at Department of Seed Science and Technology, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan to evaluate the effect of seed treatment, soil application and foliar spray with some insecticides on aphid population in bell pepper cultivar Solan Bharpur through different methods of applications. The treatments comprised of seed application of imidacloprid (Gaucho 600FS) and thiamethoxam (Cruiser 70WS), soil application of neem cake@ 2 q/acre and Carbofuran @ 6 kg/acre and foliar spray of imidacloprid (Confidor 200 SL), thiamethoxam (Actara 25 WS), indoxacarb @ 0.5ml/l, NSKE (neem seed kernel extract) 5% and neem formulation @ 2.5ml/l. Analysis of variance revealed that seed treatment with thiamethoxam (cruiser) @10 g per kg seed and two foliar sprays of thiamethoxam (Actara), (first spray after 30 days of transplanting and second spray after 15 days of first spray) were found effective in controlling aphid population in capsicum and therefore, may be recommended for bell pepper production after multiyear and multi-location trials.
