Abstract:
A field experiment was conducted at Entomology farm, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu (SKUAST-J) in rabi 2020-21 to evaluate the efficacy of selected insecticides against Thrips tabaci L. in onion. A total of nine treatments viz., Acetamiprid 20 SP, Fipronil 5 SC, Emamectin benzoate 5 SG, Imidacloprid 17.8SL, Spinosad 45SC, Thiamethoxam 25WG, Beauvaria basiana and Metarhizium anisoplae along with control were tested for their efficacy against onion thrips 18th standard week followed by the second spray in 21st standard week. All the treatments were statistically superior over control in reducing the population of T. tabaci in onion. Among different insecticides tested, Imidacloprid 17.8 SL (0.3ml l-1) proved to be superior over all other insecticides in reducing the population of onion thrips after two sprays. Thiamethoxam 25 WG (0.25gl-1), Acetamiprid 20SP (0.2gl-1) and Fipronil 5C (1.5mll-1), however, also provided efficient control over the target insect pest and were at par with Acetamiprid 20SP (0.2g l-1).
