Experiments to study the control of downy brome were conducted at three locations on Nebraska rangeland. Soils ranged from a silty clay loam to a loamy sand. Herbicide treatments included atrazine, cyanazine, metribuzin, and simazine at 0.5 and 1.0 lb/acre; glyphosate and terbacil at 0.25 and 0.5 lb/acre; secbumeton at 1.0 and 2.0 lb/acre; and paraquat at 0.25 lb/acre applied in the spring. All treatments, with the exceptions of glyphosate and paraquat, were also applied in the fall. Metribuzin at 0.33 lb/acre was also applied in the fall. Atrazine, metribuzin, and simazine effectively controlled downy brome. Downy brome control and forage production were greater when these herbicides were applied in the spring. Forage production was not significantly increased when herbicides were applied in the fall, but the trend was toward increased production. Injury to perennial cool-season forage grasses was greater from spring-applied herbicides than from fall applications. Control of downy brome was greater on fine-textured soils than on coarse-textured soils.
