| Abstract/Contents: | "Managing Poa annua is a dilemma sod producers and golf course superintendents face. Poa annua is an extremely diverse weed that thrives in cool, moist turf conditions with rich soils, but tolerates a variety of harsh environments including low frequent mowing and compacted soils. Several perennial subspecies of Poa annua exist and do not respond to preemergence herbicides once they are established. Unfortunately, these perennial Poa annua plants in time often dominate the flora. Over the past several years numerous active ingredients for managing Poa annua have been evaluated, with some of these materials showing good activity against Poa annua. However, few of these materials have displayed selectivity to creeping bentgrass. The lack of an effective selective postemergence herbicide continues to leave sod producers and golf course superintendents with few means of Poa annua control once established. One new compound, Velocity herbicide, has been evaluated in creeping bentgrass and consistently displayed selectivity against Poa annua without disrupting creeping bentgrass growth. Bispyribac-sodium, the active ingredient in Velocity herbicide, is being developed by Valent U.S.A. Corporation for use in sod farms and golf courses. Velocity has shown excellent safety to cool season turfgrass and provides postemergence control of several aggressive weeds including Poa annua, yellow nutsedge (Cyperus esculentus) and dandelion (Taraxacum officinale). Experiments were conducted throughout the United States the past four growing seasons to evaluate the potential use of Velocity on creeping bentgrass. The objective of these trials was to evaluate the performance of Velocity when applied under different environmental conditions to determine the potential for this herbicide in the turfgrass market. In addition to evaluating Velocity at several locations, treatments included evaluation of different rates, timings and application intervals. Data from these trials confirmed Velocity provides a Poa annua management strategy for sod producers and golf course superintendents." |
