Study of the efficacy of insecticides against jassid on okra

Abstract

Field experiments were conducted during Kharif 2011 to evaluate the efficacy of six insecticides against sucking insect pest jassids ( Amrasca biguttula biguttula ) on okra ( Abelmoschus esculentus L.). Spraying of difenthiuron 50 WP @ 300 g a.i./ha was found significantly more effective and the next treatment Thiamethoxam 25 WG @ 25 g a.i./ha was also significantly effective in controlling jassid population.
