Abstract

Field studies were conducted in 2018 at two locations at the H. Rouse Caffey Rice Research Station (RRS) to evaluate the activity of titrated rates of florpyrauxifen-benzyl on aquatic weeds. Florpyrauxifen-benzyl was applied at 0, 3.6, 7.3, 11, 14.6, 18.3, 22, 25.6, and 29.5 g ai ha^-1into 91-cm diameter galvanized rings containing ducksalad, alligatorweed, cattail, creeping water primrose, grassy arrowhead, and pickerelweed. Ducksalad control was 89 to 99% when treated with all rates of florpyrauxifen at 11 to 29.5 g ha^-1; however, control was reduced to 51 to 79% when treated with rates lower than …
