The field studies were conducted in the year 2017-18 to determine the efficacy of selected insecticides against leafhopper Amrasca biguttula biguttula (Ishida) of okra at PAU Regional Research Station Gurdaspur, Punjab (India). The studies revealed that all the treatments were found effective in reducing the population of leafhopper as compared to control. Thiamethoxam 25 WG @ 150 g/ha was the most effective treatment indicating reduction in population of leafhopper and increase green fruit yield followed by Imidacloprid 17.8 SL and synthetic insecticide Malathion 50 EC @ 150 and 1400 ml per hectare respectively. The highest cost benefit ratio (Rs. 1: 39.56) was achieved with Thiamethoxam and Imidacloprid (1: 38.76) followed it. The tested insecticides were also found safest to predators (spider and coccinelid) of okra insect-pests. The vegetable growers can make alternative spray of tested insecticides for management of okra leafhopper.
