Abstract

The efficacy of foliar application of imidacloprid 17.8%SL (0.33 ml/ l), acetamiprid 20%SP (0.4 g/ l), thiamethoxam 25%WG (0.5 g/ l), quinalphos 25%EC (2.0 ml/ l), neem oil 2% (20 ml/ l) and karanj oil 2% (20 ml/ l) were evaluated against leafhopper Empoasca kerri Pruthi in green gram. The most effective insecticides were imidacloprid > thiamethoxam > acetamiprid, with maximum reduction in incidence after seven days of application of second spray being 82.82 and 75.05% due to imidacloprid and thiamethoxam, respectively.
