| Abstract/Contents: | "Field experiments were conducted in 2002 and 2003 in Adelphia, NJ to evaluate fall and spring applications of bispyribac, sulfosulfuron, and primisulfuron for postemergence control of annual bluegrass in Kentucky bluegrass. Studies were initiated on Oct. 2, 2002, May 30, 2003, Sept. 25, 2003, and June 1, 2004. Sequential applications were made 30 to 40 days after intial application. Primisulfuron at 45 g/ha and bispyribac at 148 g/ha were the most effective fall treatments and plots treated with these herbicides had 16 and 13% annual bluegrass ground cover respectively, the following spring while the untreated had 42%. Both fall bispyribac treatments resulted in significant Kentucky bluegrass injury (25 to 39%) by late November and injury persisted into the following spring. In the spring studies, plots treated with primisulfuron at 45 g/ha and bispyribac at 111 and 148 g/ha had an average of 7, 7 and 4% annual bluegrass ground cover, respectively, while the untreated had 27% by mid-august. Bispyribac resulted in the greatest amount of Kentucky bluegrass injury (21 to 56%) among spring treatments. Sulfosulfuron, at 11 and 22 g/ha was safe to use on Kentucky bluegrass but provided minimal control of annual bluegrass. These studies suggest that, while bispyribac can substantially reduce populations of annual bluegrass in Kentucky bluegrass, there is risk of unacceptable injury in the fall or spring. However, primisulfuron has the potential to consistently reduce annual bluegrass populations without significant injury to Kentucky bluegrass. |
