Abstract:
The relative efficacy of twelve insecticides, viz., buprofezin 25 SC (0.04%), pyriproxyfen 10.8 EC (0.005%), diafenthiuron 50 WP (0.05%), vertimec 1.9 EC (9.5 mg/l), chlorantraniliprole 18.5 SC (0.005%), chlorfenapyr 10 SC (0.01%), emamectin benzoate 5 SG (0.005%), flubendiamide 39.35 EC (0.01%), pymetrozine 50 WG (0.025%), pyridalyl 10 EC (0.015%), bifenthrin 10 EC (0.016%) and dimethoate 30 EC (0.03%) against leafhopper, Empoasea fabae (Harris), aphid, Aphis craccivora Koch and whitefly, Bemisia tabaci (Genn.) was evaluated. The reduction in population revealed that diafenthiuron 50 WP (92.90% reduction), dimethoate 30 EC (91.77% reduction) and chlorantraniliprole 18.5 SC (90.58% reduction) were found most effective against leafhopper. The same insecticides exhibited 95.17, 94.60 and 94.04 per cent reduction in aphid population, respectively after three days of first spray. ln case of whitefly, the most effective treatments were diafenthiuron 50 WP (93.60% reduction), dimethoate 30 EC (92.04% reduction) and pyriproxyfen 10.8 EC (90.10% reduction). The treatment of pyridayl 10 EC, vertimec 1.9 EC and pymetrozine 50 WG proved to be least effective.
