| Abstract/Contents: | "Field experiments were conducted in 2000 to 2002 in New Jersey to evaluate sulfosulfuron, 1-(4,6-dimethoxypyrimidin-2-yl)-3-[(2-ethanesulfonyl-imida< >zo[1,2-a]pyridine-3-yl)sulfonylurea, for annual bluegrass (Poa annua L.) control in mature stands of Kentucky bluegrass (Poa pratensis L. 'Baron'). Treatments consisted of single or three sequential applications of sulfosulfuron at 11, 22, or 34 g ai ha-1 in fall and/or spring. Single applications at 34 g ha-1 and sequential applications at 22 or 34 g ha-1 were effective at reducting annual bluegrass cover in both fall and spring. The most consistent treatments at reducing annual bluegrass cover were three fall plus three spring sequential applications at 11, 22, or 34 g ha-1. Annual bluegrass cover in these plots averaged 7, 3, and 1%, respectively, compared to 20% in the untreated check by the summer evaluations. In plots treated with single applications at 34 g ha-1 or sequential applications at 22 or 34 g ha-1, Kentucky bluegrass quality was often reduced due to discoloration and stunting. Evidence of Kentucky bluegrass thinning was present in plots treated with six applications of sulfosulfuron at 22 or 34 g ha-1. Fall plus spring sequential applications at 11 g ha-1 reduced annual bluegrass cover with a lower risk of Kentucky bluegrass stunting and thinning. However, multiple applications of sulfosulfuron at 11 g ha-1 have the potential to discolor Kentucky bluegrrass to an extent that may be unacceptable to some turf managers." |
