Abstract:
Field experiment was conducted at College of Horticulture Farm, Munirabad, Koppal during Kharif 2017-18, 2018-19 and 2019-20 to evaluate relative efficacy of existing insecticide molecules against mango leaf webber in the established mango orchard. The cumulative mean of pest incidence of three seasons of two sprays revealed that all the treatments showed comparative decrease in spread of the mango leaf webber infestation, but the treatment of Lambda-cyhalothrin 5 % EC @ 1 ml/l was found effective in reducing the larval population with highest yield of 61.88 q/ha with B: C ratio of 4.42 followed by Quinalphos 25 % EC @ 2 ml/l which was recorded the yield of 57.74 q/ha with B: C ratio of 4.08.
