Abstract

                                Bioefficacy of imidacloprid 200 SL was evaluated against thrips and aphids on groundnut during kharif 1998 and rabi 1998. Imidacloprid 200 SL. at doses 100, 150, 200 and 250 ml ha were tested against these pests with dimethoate and methyl-o-demeton at 500 ml ha as standards. Imidacloprid at 100 ml ha effectively checked the population of thrips and aphids on groundnut and was superior to the standard chemicals. The effect of imidacloprid spray persisted for three weeks

Key words : Arachis hypogaea, Bioefficacy, Aphids, Thrips, Imidacloprid
