摘要

Field evaluation of the bioefficacy of certain new insecticides aiongwith traditional insecticides as foliar spray against chilli thrips, Scirtothrips dorsali* and mites, Polyphagotarsonemus latus was undertaken under irrigated conditions during 2001and 2002. Results indicated that among 17 insecticides tested, Fipronil 5% SL @ 0.01% followed by Thiomethoxam 25 WG @ 0.005%, Acetamiprid 20 SP @ 0.002% and Dimethoate 30 EC @ 0.06% were found'to be more effective against thrips, as they reduced thripspopulation, while Carbaryl 50 SP @ 0.15% followed by Phosalone 50 EC @ 0.07%, Chloropyriphos 20 EC 2 0.05% were found to be least effective. Fipronil 5% SL @ 0.01 % followed by Thiomethoxam 25 WG @ 0.005%, Dicofol 18.5 EC @ 0.09% were found to be effective against mites, while Carbaryl followed by Dichlorovas 76 EC 2 0.076% and Indoxacarb 145 SL @ 0.0145% were found to be ineffective against mites.
