Abstract
The present study was conducted to study the effect of chlorpyrifos cartap granule(8%) on controlling sugarcane borer under filed conditions.The pesticide terbufos granule(5%) @ 3.0 kg ai/ha was used as the control,and chlorpyrifos cartap granule(8%) was applied @ 2.0,2.5 and 3.0 kg active ingredients(ai)/ha in loose and uphill soil.The application of chlorpyrifos cartap granule(8%) resulted in over 75% control efficacy on sugarcane borer after applying 60 and 90 days,though it was quite similar to the control,there were no significant differences.On the basis of results obtained in this study,it is suggested that 8% chlorpyrifos cartap granules may be used to control sugarcane borer when applied @ 2.0-3.0 kg ai/ha at the time of planting for plant crop or loosening soil for ratoon crop.
