MANAGEMENT OF EARLY SEASON PESTS OF CHILLI (Capsicum annuum L.) BY DIFFERENT INSECTICIDAL APPLICATION METHODS IN ARID WESTERN RAJASTHAN

摘要

The experiments were conducted during rainy seasons to evaluate the efficacy of different insecticides by different methods for controlling the major pests viz. Thirps [Scirtothrips dorsalis Hood] and yellow-mites [Polyphagotarsonemus latus (Banks)] infesting chilli (Capsicum annuum L.). Among sixteen treatments, comprised of six different application techniques, soil application of phorate 10% granules @ 3 g/m~2 in nursery-bed before sowing followed by seedling root-dip (SRD) in monocrotophs (0.05%)solution before transplanting proved highly effective combination against the pests and in reducing the leaf curl disease intensity. However, this treatment was equally effective with another combination treatment of carbofuran 3% granules @ 10 g/m~2 followed by SRD in acephate (0.05%). Among other treatments, seed treatment with carbosulfan 25 std (5%) followed by SRD in carbosulfan 25 EC (0.05%), foliar spray of monocrotophos (0.04%), acephate (0.05%) and methyl-demeton (0.025%) on seedlings (3 weeksold) were next best effective group as compared to remaining treatments.
