- Abstract
A field experiment was conducted during kharif 2010 and 2011 at Oilseeds Research Institute, AARI, Faisalabad, Pakistan to find out and compare the efficacy of new chemistry (emamectin benzoate, spinosad) and conventional insecticides (bifenthrin, chlorpyriphos, profenophos) against Helicoverpa armigera (Hubner) on sunflower hybrid FH-385. The emamectin benzoate and spinosad proved to be highly effective against H. armigera. After 72 hours of treatment emamectin benzoate showed 95.93% and 93.75%, while, spinosad showed 93.02% and 91.04% mortality in 2010 and 2011, respectively. Whereas, the conventional insecticides i.e. bifenthrin and profenophos showed lesser mortality. Moderately effective response was observed for chlorpyriphos. The new chemistry insecticides have proven better in controlling H. armigera as compared to the conventional ones.
