Abstract
The field experiment was carried out to evaluate of bio-efficacy of insecticides against aphids infesting chilli 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 results regarding overall mean of three sprays against aphids revealed that treatment thiamethoxam 25 WG @ 0.01 percent recorded (5.03) and was at par with treatment imidacloprid 17.8 SL @ 0.004 percent (5.32). All the above treatments were found superior to untreated control.
