| Abstract/Contents: | "Annual bluegrass (Poa annua) is a problematic winter annual weed and seashore paspalum (Paspalum vaginatum) is injured by most postemergence herbicides that are effective for control. However, seashore paspalum has shown acceptable tolerance levels to flazasulfuron during active growth and treatments may have potential for postemergence annual bluegrass control in spring. The objective of this research was to evaluate application timing of single and sequential flazasulfuron applications alone or with amicarbazone in seashore paspalum and bermudagrass (Cynodon dactylon) fairways. Treatments were applied at dormancy or during initial greenup and sequential treatments were made at three week intervals. Sequential flazasulfuron at 26 g ai/ha were required for >80% control at both timings and were similar to single applications of 52 g ai/ha. Single applications of flazasulfuron at 26 g ai/ha provided poor (<70%) annual bluegrass control at both timings after six weeks but the addition of amicarbazone improved control at the later application timing. Although several treatments were effective for annual bluegrass control, seashore paspalum had unacceptable injury (>20%) from all flazasulfuron treatments and application timings. Seashore paspalum injury was acceptable (<20%) from exclusive amicarbazone applications suggesting further research is needed to evaluate potential for annual bluegrass control in spring." |
