| Abstract/Contents: | "In the transition zone, crabgrass and goosegrass are problematic weeds, especially on creeping bentgrass greens experiencing biotic or abiotic stress. Creeping bentgrass maintained at greens height is typically more sensitive to herbicides. Currently, there are no postemergence herbicides registered to control crabgrass or goosegrass on creeping bentgrass greens. Experimental results have shown that fenoxaprop can be applied at low doses weekly or biweekly on greens to control young weed seedlings as they emerge. Our objective was to evaluate this frequent-treatment, lowdose approach with fenoxaprop, topramezone, quinclorac, and siduron for crabgrass and goosegrass control, as well as creeping bentgrass response. Both quinclorac applied weekly and biweekly at 140 and 280 g ai/ha, respectively, and fenoxaprop applied weekly and biweekly at 17 and 35 g ai/ha, respectively, injured creeping bentgrass 30 to 60% at 52 days after initial treatment. Siduron at 5.6 or 13 kg ai/ha applied weekly or biweekly, respectively, did not injure creeping bentgrass and topramezone applied at 1.5 to 6.1 g ai/ha caused transient injury that never exceeded 15%. Fenoxaprop controlled both crabgrass and goosegrass while quinclorac controlled only crabgrass. Siduron completely controlled crabgrass but controlled goosegrass approximately 50% by the end of the season. Topramezone completely controlled goosegrass but controlled smooth crabgrass approximately 60% by the end of the season. Due to the higher price of siduron relative to other treatments, additional studies were conducted to evaluate lower rates of siduron for smooth crabgrass control. In these studies, siduron completely controlled smooth crabgrass (>95%) when applied biweekly at four rates between 3.3 and 13 kg ai/ha. By reducing the siduron rate from 13 kg ai/ha to 3.3 kg ai/ha, a golf course, with four acres of putting greens, could reduce potential economic burden from $13,335/yr to $3,150/yr. Siduron is currently the only herbicide included in these studies that is registered for use on golf greens. These data suggest siduron, even at reduced rates, is a safe option for season-long control of crabgrass and suppression of goosegrass." |
