Keywords:

Three pre-mix herbicide combinations at two different times of application, viz. pendimethalin + penoxsulam at 5 and 10 DAS, cyhalofop-butyl + penoxsulam and florpyrauxifen-benzyl + cyhalofop-butyl both applied at 12 and 18 DAS were evaluated along with sequential spray of cyhalofop-butyl fb chlorimuron-ethyl 10% + metsulfuron-methyl 10% at 18 and 19 DAS, bispyribac-sodium at 18 DAS, hand weeding at 20 and 40 DAS and unweeded control. At 30 DAS, the lowest weed dry matter and highest weed control efficiency was obtained with application of florpyrauxifen-benzyl + cyhalofop-butyl (150 g/ha) at 12 DAS. The highest numbers of yield attributes and crop yields in rice were recorded in hand weeding followed by florpyrauxifen-benzyl + cyhalofop-butyl at 12 DAS and pendimethalin + penoxsulam (625 g/ha) at 5 DAS.
