| Abstract/Contents: | Suggests pre and postemergent methods that may help prevent or control crabgrass. States that "crabgrasses (genus Digitaria) are very common warm season weedy grasses on athletic surfaces." Explains that "crabgrass begins to germinate in January in the extreme southern U.S. [United States]. The germination date is later as in the northern states, with the upper Midwest typically seeing crabgrass germination in mid April." Suggests that the "first lines of defense against crabgrass infestation are the preemergence herbicides." Explains that "these products form a barrier in the soil and once a germinating seedling contacts it, the weed is controlled. For a preemergence herbicide to be effective, it must be applied before weed seed germination that occurs after the last killing frost of the season." Profiles possible postemergence control products, including Dimension and Echelon. Announces the introduction of Tenacity, a herbicide "that contains the active ingredient mesotrione. The active is in a unique class of chemistry and this product has a very diverse label, including pre- and postemergence control of both broadleaf weeds and annual grasses. It also controls sedges preemergence and certain perennial weedy grasses postemergence." States that "regardless of the choice of herbicide, control of crabgrass is better if applied to young plants that have not tillered." Concludes that "crabgrass is a nearly ubiquitous weed in turfgrass. In athletic field management, its presence has been particularly challenging because spring time overseeding often precludes the use of a preemergence herbicide. However...herbicides such as quinclorac...and...mesotrione should make the athletic field manager's job easier when it comes to controlling this weed." |
