Weed management with ready-mix herbicides in wet seeded rice

Abstract: The efficacy of new ready-mix herbicides i.e., pendimethalin + penoxsulam, cyhalofop-butyl + penoxsulam and florpyrauxifenbenzyl + cyhalofop-butyl were evaluated in direct-wet seeded rice. They were compared with the sequential application of cyhalofop-butyl fb (chlorimuron ethyl 10% + metsulfuron methyl 10%), bispyribac sodium, as well as hand weeded and unweeded controls. At 30 DAS, the lowest dry matter production was obtained in florpyrauxifen-benzyl + cyhalofop-butyl applied at 12 DAS. Nutrient removal followed a similar trend to weed dry weight. Highest grain yield was obtained in hand weeded control, which was found at par with all ready-mix herbicide treatments. Higher net returns and B:C ratios were obtained with readymix herbicides than with hand weeding.
