Commercially important weeds in flooded rice are controlled by in-water application of the auxin herbicides 2,4-D, triclopyr, fluroxypyr, and clopyralid. At application rates of about 35 to about 1120 grams acid equivalent per hectare (g ae/ha), 2,4-D, triclopyr, fluroxypyr, and clopyralid are highly efficacious on several commercially relevant grass, broadleaf and sedge weeds and cause little to no rice crop injury.
