| Abstract/Contents: | "Poa annua is among the most problematic weeds in turfgrasses during the winter season. Preemergence control can be initiated in the non-overseeded bermudagrass or overseeded winter turfgrass using dinitroaniline herbicides in the late summer or fall season. Sequential applications can provide season-long reduction of P. annua. When cool-season overseeded grasses are planted, few selective postemergence herbicides are available and they include ethofumesate, amicarbazone, and most recently introduced methiozolin. More options are available for use in dormant bermudagrass that is not overseeded. Many non-selective postemergence herbicides such as glyphosate, diquat, glufosinate, simazine, indaziflam, flumioxazin, and the ALS enzyme-inhibiting herbicides can accomplish the goals of minimizing P. annua populations. The timing and sequence of a combination of applications of preemergence and postemergence herbicides can be effective and also present phytotoxic effects on the turfgrasses. Several approaches of combining preemergence with postemergence herbicides or singular applications will be described." |
