| Abstract/Contents: | "Greenhouse experiments were conducted to determine efficacy of herbicides used in cool season turfgrass against false-green kyllinga (Kyllinga gracillima) emergence from seed in soil. A replicated preliminary experiment evaluated various herbicides at 100 and 10% typical use rates for cool season turfgrass. Herbicides and 100% use rates included bensulide (11,200 g ha-1), corn gluten meal (880,000 g ha-1), dimethenamid (1,680 g ha-1), dithiopyr (560 g ha-1), isoxaben (1,120 g ha-1), mesotrione (280 g ha-1), methiozolin (516 g ha-1), oxadiazon (4,500 g ha-1), pendimethalin (3,360 g ha-1), prodiamine (840 g ha-1), siduron (13,500 g ha-1), and sulfentrazone (280 g ha-1). The 100 and 10% use rate applications of corn gluten meal, pendimethalin, methiozolin, and siduron were less effective than sulfentrazone, dithiopyr, isoxaben, oxadiazon, prodiamine, dimethenamid, and bensulide against false-green kyllinga from seed.Herbicides deemed effective in the first experiment were evaluated in a greenhouse dose-response experiment. Treatments were a complete factorial of weed species (false-green kyllinga and smooth crabgrass), herbicide, and herbicide rate. Herbicides were applied at 100, 50, 25, 12.5, 6.3, and 3.1% of typical use rates for cool season turfgrass. Herbicides evaluated were bensulide, dimethenamid, dithiopyr, isoxaben, oxadiazon, prodiamine, and sulfentrazone. Local collections of false-green kyllinga seed were sowed to 10 by 10 cm pots filled with local field soil. Smooth crabgrass (Digitaria ischaemum) was seeded to separate pots as a standard for comparison. Treatments were replicated four times. Seedlings were counted at 42 days after application and expressed as a percent of the non-treated control. Data were analyzed as a three-way complete factorial using the GLIMMIX procedure in SAS (P= 0.05). Fisher's protected LSD test was used to separate means. Main effect interactions were detected (P < 0.05) for seedling count expressed as a percent of the non-treated control 6 weeks after treatment. Bensulide, dimethenamid, and oxadiazon provided >94% false-green kyllinga control at all rates. Dithiopyr, prodiamine, sulfentrazone and isoxaben provided less false-green kyllinga control than bensulide and oxadiazon at 3.1 and 6.3% rates. Prodiamine, isoxaben, and oxadiazon provided more smooth crabgrass control than false-green kyllinga control at 6.3, and 3.1% rates. Sulfentrazone controlled more false-green kyllinga than smooth crabgrass at the 12.5% rate. Prodiamine, pendimethalin, and dithiopyr are less effective against false-green kyllinga seed than smooth crabgrass. Sulfentrazone applied preemergence is more effective against false-green kyllinga than smooth crabgrass. Bensulide and oxadiazon were the most effective herbicides evaluated for preemergence control of false-green kyllinga seed in a controlled environment." |
