Abstract

Field experiments were conducted to determine whether residual sulfonylurea herbicides applied at cheat suppression rates affect hard red winter wheat forage production and grain yield. Triasulfuron at 30 g/ha or chlorsulfuron plus metsulfuron at 26 g/ha applied PRE and metribuzin applied early POST alone at 280 g/ha or tank-mixed with triasulfuron at 158 + 30 g/ha or chlorsulfuron plus metsulfuron at 210 + 21 g/ha, all decreased total forage production of weed-free wheat. Conversely, all herbicide treatments except triasulfuron applied PRE increased wheat grain yield.
