| Abstract/Contents: | "Research has shown that perennial ryegrass can outcompete annual bluegrass (Poa annua) for resources needed for growth and development. However, little is known about the effect of perennial ryegrass overseeding rate on annual bluegrass populations. A southeastern regional study evaluating the combined use of single applications of bispyribac-sodium at 150 g ha-1 along with four perennial ryegrass overseeding rates (0, 224, 448, and 672 kg seed ha-1) was initiated in 2003 to determine the effects on annual bluegrass control. Annual bluegrass population decreased as perennial ryegrass (Lolium perenne L.) overseeding rate increased. Bispyribac-sodium applications injured annual bluegrass 2 weeks after treatment, but were not significantly different from the nontreated plots 4 weeks after treatment. Injury to perennial ryegrass did not exceed the unacceptable level and injury was seldom observed 2 weeks after treatment." |
