| Abstract/Contents: | "Carbon seeding commonly is used to increase the crop safety of diuron in perennial ryegrass seed fields in western Oregon. Diuron also is used to control weeds in established perennial ryegrass. Recently, annual bluegrass (Poa annua) developed resistance to urea herbicides, reducing the effectiveness of this herbicide program for most growers. Field studies were initiated in 1998 and 1999 near Corvallis, OR to find alternative-site-of-action herbicides for use in newly planted and established perennial ryegrass fields. Treatments of clomazone, norflurazon, and sulfentrazone applied to fall carbon-seeded perennial ryegrass controlled annual bluegrass 89 to 100% and did not reduce seed yield. Spring-1999-carbon-seeded perennial ryegrass injury from application of norflurazon, sulfentrazone, or azafenidin was acceptable; however, carbon seeding did not prevent crop injury from pendimethalin or flufenacet-metribuzin. This trial was not taken to yield. Injury to perennial ryegrass carbon-seeded in Fall, 1999 at three locations was acceptable with applications of norflurazon, clomazone, sulfentrazone, or azafenidin; effects on yield will be measured in 2000. Clomazone, norflurazon, and sulfentrazone, alone and in combinations with oxyfluorfen, diquat, or glufosinate, were applied to established stands of perennial ryegrass with acceptable levels of crop injury and weed control in 1998 and 1999." |
