Abstract: Studies on the effect of new molecules and biorationals against thrips on watermelon were conducted at the University of Horticultural Sciences, Bagalkot during 2017-18. Mean data on efficacy of various treatments recorded after three rounds of sprays revealed that, cyantraniliprole 10.26 OD @ 1.5ml/l found to be highly effective in reducing the thrips population (1.39 thrips/vine) as compared to other insecticides evaluated. Acephate 75 SP @ 1g/l, diafenthiuron 50 WP @ 1g/l and thiamethoxam 25 WG @ 02g/l recorded to be the next best treatments in the order of efficacy (3.10, 3.29 and 3.61 thrips/vine, respectively). While, triazophos 40 EC @ 2ml/l found to be least effective (8.20 thrips/ vine). Among the biorationals tested, spinosad 45 SC @ 0.2ml/l (4.57) and azadirachtin 10000 ppm @1ml/l (5.09) were considered to be effective in reducing thrips on watermelon.
