- Abstract
This study evaluates the toxicity of eight insecticides against Helicoverpa armigera (Hubn.). These include conventional and newer molecules which are being used on a large scale in six districts (Raichur, Kalaburagi, Bidar, Dharwad, Ballari, Bengaluru and Gangavathi) of north eastern Karnataka. The results revealed that the least LC50 value was observed in chlorantraniliprole 18.5%SC (0.17-0.39 ppm-2014-15; 0.19-0.43 ppm-2015-16; and 0.70-0.94 ppm-2016-17. Maximum LC50 value was observed with chlorpyriphos 20%EC (35.16-41.08; 37.35-43.27; and 36.02-41.94 ppm). The order of toxicity was chlorantraniliprole > emamectin benzoate > flubendiamide > spinosad > thiodicarb > methomyl > profenophos > chlorpyriphos. These results reveal that rotation of conventional insecticides along with the new insecticides might be more effective.
