Abstract

Herbicides were evaluated for weed control in seedling perennial grass stands at six locations in eastern Washington. Most annual weeds commonly found in grass seed fields were controlled by 2-methoxy-3,6-dichlorobenzoic acid (dicamba), 2,3,6-trichlorobenzoic acid (2,3,6-TBA), and 1-butyl-3-(3,4-dichlorophenyl)-1-methylurea (neburon). Dicamba was the most effective herbicide for annual weed control but caused some injury to Kentucky blue-grass seedlings. Seedling grasses injured by dicamba recovered and became established in each trial. Grasses were injured about the same extent when treated with 2,3,6-TBA as when treated with dicamba, but 2,3,6-TBA did not control as many weed species. Neburon did not control as many species as dicamba and 2,3,6-TBA but was effective in killing a large number of species without measurable injury to grass seedlings.
