Abstract

Field experiments were conducted in two crop seasons during 2006 with Ajeet 333 okra to evaluate the efficacy of neonicotinoid, imidacloprid as foliar application against jassid, Amrasca biguttula biguttula (Ishida) and whitefly, Bemisia tabaci (Gennadius). Imidacloprid 17.8 SL at 25 g a.i. ha−1 was found effective against jassids and whiteflies. The other neonicotinoid, thiamethoxam also provided similar levels of protection as that of imidacloprid. The conventional insecticide, methyl demeton (125 g a.i. ha−1) was less effective.
