Abstract

AbstractThe aim of this study was to evaluate the effectiveness of sequential herbicide applications in combination with mechanical and manual weeding in wet-seeded rice (WSR) seeded by drum seeder during the Navarai season (January - April, 2025) at SRM College of Agricultural Sciences, Tamil Nadu, India. A Randomized Block Design replicated three times was used. The sequentially applied pre-emergence application (PE) of bensulfuron-methyl + pretilachlor 660 g/ha followed by (fb) post- emergence application (PoE) of florpyrauxifen-benzyl + cyhalofop-butyl 150 g/ha recorded the lowest weed density and biomass at all the recorded dates of 20, 40, 60 days after seeding (DAS) with highest weed control efficiency (82.4%), grain yield and straw yield of WSR seeded by drum seeder.

8 of 10 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
