Abstract/Contents:"Primisulfuron is registered in the Pacific Northwest for use in Kentucky bluegrass. Primisulfuron is a sulfonylurea herbicide that is particularly effective on downy brome. Since sulfonylurea herbicides often have soil residuals that can injure subsequent rotational crops, studies were established to determine which crops might be injured after use of primisulfuron. Primisulfuron was applied at 40, 80 and split application of 20/20 g/ha to either seedling or established Kentucky bluegrass. Primisulfuron was applied to seedling Kentucky bluegrass at the Central Oregon Agricultural Research Center near Madras, OR. Kentucky bluegrass was planted in 1996, Trial 1, and in 1997, Trail 2 (Table). The soil was a Madras sandy loam with a pH of 6.8 and an organic matter content of 1.4%. During the winter of 1996-1997, Trial 1 was flooded with 4 inches of water for about 2 months. The seedling Kentucky bluegrass was sprayed with glyphosate in early spring to simulate the loss of the seedling Kentucky bluegrass stand. The trials were replanted in the spring of 1997 (Trial 1) and 1998 (Trial 2) to alfalfa, canola, spring wheat, and sugarbeets. In Trial 1, above ground biomass was reduced by an average of 7, 25, 33, and 75% for alfalfa, spring wheat, canola, and sugarbeets, respectively. In Trial 2, above ground biomass was reduced by an average of 70% or greater for all crops planted. In a second set of studies, primisulfuron was applied to established grass seed crops in the Lower Umatilla Basin and Grande Ronde Valley of OR, and the Columbia Basin of WA in 1996. The established grass seed crops were harvested and replanted to sweet corn, onions, potatoes, winter wheat, peppermint, or sugarbeets during the next growing season. Carry-over effects of primisulfuron were detected on potato, winter wheat, and sugarbeets."
