Abstract

Among the sucking insect pests whitefly, Bemisia tabaci is one of the key sucking pests in Punjab area of sub-continent. The bio-efficacy check of different pesticides against whitefly, Bemisia tabaci in tomato cv. GT. 2 based in field analysis was carried out at Agricultural University, of Punjab, during Rabi 2019-20. Eight treatments were selected to evaluate the efficacy including untreated control in Randomized Block Design with four replications. The low number of whitefly population (2.17adults/leaf) was observed for the chemical imidacloprid 17.8 SC @ 0.005% (2.7 ml/10 L of water) followed by 2.24 adults/leaf in dimethoate 30 EC @ 0.03% (10 ml/10 L of water) which were significantly at par with each other. Neem extract (azadirachtin) was at the third position 3000 ppm with concentration of 3 ml/litre of water (5.67 adults/leaf).
