Relative toxicity of selected insecticides against adult whitefly, T. vaporariorum in potted condition

Sachin US and Suchithra Kumari MH

The present experiment was conducted to assess relative toxicity of selected insecticides against whitefly in the Entomology laboratory at College of Horticulture, Mudigere during the year 2014-2015. Among the eleven treatments, imidachloprid, thiamethoxam and cyantraniliprole were highly toxic to adults which recorded 100 per cent mortality, four days after treatment. Cyantraniliprole recorded the highest adult mortality comparatively early than imidachloprid and thiamethoxam. Fipronil 80% WG, recorded 100 percent mortality five days after treatment which was followed by emamectin benzoate 5% SG at sixth day after treatment and recorded as next best treatments under laboratory condition against whitefly. Acephate 75% SP and azadirhactin 10000 ppm recorded highest level of mortality (100%) at seventh and eighth day after treatment, respectively which was followed by triazophos 40% EC, spinosad 480% SC and buprofezin 25% SC at eleventh day after treatment. Considering the result, cyantraniliprole, thiamethoxam and imidacloprid were recommended for effective control of sucking pests in cotton ecosystem.
