ABSTRACT

The field efficacy of different bio pesticides and insecticides was studied on number of larvae per plant, also on grain and fodder yield against stem borers (Chilo partellus and Sesamia inferens) in Kharif maize in Shivamogga, Karnataka. All the treatments were found significantly effective in reducing the infestation of stem borers and increasing the yield compared with control. Treatment Chlorpyriphos 20 EC (Seed treatment-ST + Foliar spray-FS) was found best among all the treatments by recording lowest mean number of larvae per plant (2.80) followed by azadirachtin (4.47). Similarly, chlorpyriphos ST + FS was found to be most effective by recording highest grain yield (30.47q ha-1) and fodder yield (42.06q ha-1).

Key word: Chilo partellus, Sesamia inferens, Chlorpyriphos, grain yield
