Abstract:

An interactive survey was conducted during 2016-17 to document insecticide usage pattern adopted by the farmers of Karnataka state to manage polyphagous pest Helicoverpa armigera in different host crops growing areas. Among the different group of insecticides the most popular amongst the farmers were emamectin benzoate 5 SG (39.44 %), rynaxypyr 18.5 SC (27.22 %) and profenophos 50 EC (23.89 %). The dominant host crops for H. armigera different in the state were cotton, pigeonpea in Raichur and Kalaburgi, chickpea (Gadag), chilli (Haveri) and tomato (Kolar). Manually operated knapsac sprayer was commonly used in all localities except in Raichur and Kalaburgi where power operated sprayers were used. The refugia usage in Bt cotton was about 40% farmers only.
