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.
