摘要

The present study was carried out at G.B. Pant University of Agriculture and Technology, Pantnagar during rainy seasons 2014 and 2015 to determine the efficacy of post-emergence application of cyhalofop-butyl in managing weeds in direct-seeded rice. Eight treatments, viz. cyhalofop-butyl 10% EC at 65,75, 80 and 90 g/ha, cyhalofop-butyl 10% EC at 75 and 80 g/ha, hand weeding twice at 20 and 40 DAS and untreated control were laid out in a randomized block design with three replications. Application ofcyhalofop-butyl controlled grassy weeds better than the non-grassy weeds and recorded maximum weed control efficiency, higher yield attributes and yield. Application of cyhalofop-butyl in rice did not show any phytotoxic effect on succeeding wheat.
