Abstract

Field efficacy of some novel insecticides was evaluated against chilli thrips Scirtothrips dorsalis (Hood). Acetamiprid 20SP, spinosad 45SC, fenpyroximate 5EC, emamectin benzoate 5SG, fipronil 80WG, spiromesifen 22.9SC, diafenthiuron 50WP, acephate 75 SP and dimethoate 30EC were included. Among these, fipronil 80WG and spiromesifen 22.9SC were found superior with least incidence (0.98 and 1.04 thrips/ leaf, respectively) and 75.6 and 74.1% reduction over untreated control, respectively. Spiromesifen 22.9SC led to maximum reduction in leaf curl and fruit curl (84.6 and 83.1%, respectively) with maximum chlorophyll content in leaves and green chilli yield (93.85 q/ ha).
