Abstract: | The current studies were carried out at Government Agricultural Farm, Vehari, Pakistan to evaluate the toxicity of new chemistry insecticides for thrips (Thrips tabaci) management at early growth stage of Bt cotton during 2012. Chemical insecticides, viz. Pirate 360SC, Tracer 240SC, Radiant 120SC, Confidor 200% SL, Actara 25WG, Acephate 75SP and Novastar 56EC were applied twice at an interval of 15 days when population of the pest reached at economic threshold level. Pirate, Novastar, Tracer, Radiant and Acephate were highly effective against T. tabaci after 7 days of spray, while Confidor was comparatively less effective. Actara gave reduction in population of the pest up to three days after spray and it proved ineffective with increase in its population seven days after application. Pirate, Novastar, Tracer, Radiant and Acephate may be recommended to farmers for management of T. tabaci in Bt cotton under field conditions. |
