Abstract: Field experiments were conducted to evaluate the efficacy of botanicals and newer insecticide molecules against thrips in jasmine. In the present study, pungam (Karanj) oil @ 2 per cent treated plants harboured minimum number of thrips on a par with Vitex negundo leaf extract @ 5 per cent (2.32/leaf), NSKE @ 5 per cent (2.41/leaf) stood next and were on a par between themselves. Among the insecticides, Imidacloprid 17.8 SL @ 0.30 ml /lit, Flubendiamide 39.35 SC @ 0.75 ml / lit and Thiacloprid 21.7 SC @ 0.60 ml/lit were found effective against thrips recording a reduction of 76.00, 74.67 and 72.00 per cent, respectively. The results from the present investigation can provide timely lead and valuable information towards the development and perfection in IPM programme in jasmine.
