| Abstract/Contents: | "Grass seed production in the Pacific Northwest is in transition from reliance on open-field burning to systems integrating mechanical removal of postharvest crop residues with chemical weed control. Field tests of the ability of these systems to meet current seed certification standards while maintaining normal seed yields were initiated in 1989. Fourteen herbicide treatment sequences plus an untreated check were evaluated under five residue removal systems at two sites during two consecutive growing seasons. Residue removal methods were three non-burn systems varying in thoroughness of residue removal and two methods of burning. Among the nonburn systems, adequate control of volunteer perennial ryegrass (Lolium perenne L.), the most abundant weed in all tests, was most readily achieved in plots where residue was most thoroughly removed. Herbicide treatments providing the best weed control in both years at both sites included preemergence (PRE) metolachlor [2- chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1- methylethyl) acetamide] followed by postemergence (POST) oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4- (trifluoromethyl)benzene] plus diuron [N'-(3, 4-dichlorophenyl)-N,N-dimethylurea] PRE metolachlor followed by POST diuron, and PRE pendimethalin [N-(1- ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine] followed by POST oxyfluorfen plus diuron provided adequate weed control in most residue removal systems, but was marginal in the least thourough residue removal system. With properly chosen herbicide treatments, seed certification standards for perennial ryegrass can be met without field burning." |
