abstract
Whitefly, Bemisia tabaci is one of the major injurious sucking pests in Gujarat as well as in India. The field experiment based on bio-efficacy of different pesticides against whitefly, Bemisia tabaci in tomato cv. GT. 2 was conducted under field condition at Navsari Agricultural University, Navsari, Gujarat during Rabi 2014-15. Eight treatments including untreated control were imposed in Randomized Block Design with four replications. Lowest whitefly population (2.18 adults/leaf) was recorded in imidacloprid 17.8 SC @ 0.005% (2.8 ml/10 L of water) followed by 2.22 adults/leaf in dimethoate 30 EC @ 0.03% (10 ml/10 L of water) which were significantly at par with each other. Next in the order of effectiveness was azadirachtin 3000 ppm at 3 ml/litre of water (5.69 adult/leaf).
