Abstract:
Karanj oil, neem oil, Bt, imidacloprid and their combination were tested against maize stem borer (Chilo partellus) in the field during Kharif 2010. The combination of karanj oil+imidacloprid (10ml+2ml/l) was significantly reduced the stem borer damage i.e. Dead heart (2.8%), plant infestation (14.1%), stem tunneling (2.7%), number of exit hole/plant (0.6). The next best treatment was neem oil +imidacloprid (10ml+2ml/l) and imidacloprid (2ml/l). Grain yield was also maximum in karanj oil +imidacloprid (39.5 q/ha) closely followed by neem oil +imidacloprid (37.5q/ha).
