Abstract

The research provides updated information on the effect of different insecticides and biopesticides against maize stem borer (Chilo partellus Swinhoe) were carried out at different areas by different scientists. Combining Imidacloprid and Trichogramma chilonis resulted in significantly decreased leaf injury m-2 (1.32) and dead hearts (4.16%) in several trials done in different agroclimatic zones. With maximum grain yield (39.5 q/ha), imidacloprid + Karanj oil significantly reduced dead heart (2.8%), plant infestation (14.1%), stem tunneling (2.7%), and number of exit holes per plant (0.6). Results of the field bio-efficacy study showed that at, Chloropyrifos 50% + Cypermethrin 5% @2500 g.a.i./ha recorded significantly lower larval populations (1.18 larvae per plant) and a lower percentage of plant damage (9.00%). As per the findings this study suggests the percentage infestation and larval population of Chilo partellus can be minimized by the application of combinations of insecticides and biopesticides.
