ABSTRACT  

The efficacy of various insecticides on stem borer (Chilo partellus Swinhoe) in sorghum variety HC 308 was tested in a field experiment during 2016 at a farmer’s Agricultural Farm, Chandan Nagar, Hisar, Haryana. The experiment was designed in the form of a Randomized Block Design where seven treatments existed which were various doses of carbofuran 3% CG and neem seed kernel extract (NSKE). Data concerning percent plant infestation and yielding of grains were noted. The findings showed that the most effective treatment was carbofuran 3% CG @ 10 kg/ha (T3) with the lowest infestation (16.12%), and highest yield (20.52 q/ha). NSKE treatments were moderately effective with the untreated control recording the highest infestation (53.68) and lowest yield (6.76 q/ha). Infestation was considerably less than control by all treatments. The paper shows that carbofuran is the best in managing stem borers, although more environmentally friendly solutions such as NSKE can provide moderate management.
