The study was conducted to evaluate the two sprayers for bioefficacy was carried out in cotton (Bt) and pigeonpea at the farmer’s field, Raichur during 2017-18. The insecticide used [dinotefuran (osheen)] was solution with a recommended dose 150 g 500 l-1. The chemical used for spraying the pigeonpea crop was emamectin benzoate (ASTRA). The chemical was mixed with water at a proportion of 100 g 500 l-1. The insects were reduced from pre counting as the number of days increased after the spraying. The populations of aphids were 10, after 5 days reduced to 2.5 numbers. Conventional method of tractor operated gun spraying recorded higher pod borer population. The overall, present study concluded that tractor operated automatic sprayer is found to be superior when compared to conventional gun spraying for the management of pod borer.
