The information on efficacy of new low-dose herbicides and herbicide mixtures is very limited in transplanted rice. An experiment was conducted, to study the effect of herbicides and herbicide mixtures on weed control in transplanted rice. Lower weed density and dry weight was recorded with florpyrauxifen-benzyl + cyhalofop-butyl and penoxsulam + cyhalofop-butyl which was at par with hand weeding at 20 and 40 DAT. Herbicide mixtures were more effective to control weeds than single application of either pre- or post-emergence herbicides. Higher grain and straw yields were obtained with florpyrauxifen-benzyl + cyhalofop-butyl EC 150 g/ha PoE fb hand weeding at 40 DAT which was comparable to minimum competitive plot.
