Field evaluation of insecticides against chilli thrips (Scirtothrips dorsalis Hood)

The present investigation was carried out to field evaluation of insecticides against chilli thrips (Scirtothrips dorsalis Hood) during rabi season of 2016-17 at Central Experimental Station, Wakawali, Dist- Ratnagiri. During this experiment total seven insecticides tested viz., acetamiprid 20 SP @ 0.004, dimethoate 30 EC @ 0.6, emamectin benzoate 5 SG @ 0.002, imidacloprid 17.8 SL @ 0.004, lambda cyhalothrin 5 EC @ 0.018, spinosad 45 SC @ 0.014 and thiamethoxam 25 WG @ 0.01 percent, respectively. The overall efficacy of all three sprays revealed that spinosad 45 SC @ 0.014 percent was the best treatment which recorded minimum (1.41) mean thrips population per three leaves per plant and was significantly superior over all other treatments followed by emamectin benzoate 5 SG @ 0.002 percent recorded (1.92) and was at par with thiamethoxam 25 WG @ 0.01 percent recorded (2.09).
