Abstract/Contents:"A replicated greenhouse experiment was conducted to evaluate the efficacy of preemergence herbicides against false-green kyllinga (Kyllinga gracillima) establishment from seed in New Brunswick, NJ and West Lafayette, IN. Treatments were a complete factorial of weed species, herbicide, and herbicide rate. 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. Herbicide treatments were applied at 10 and 100% of typical use rates for crabgrass control in cool season turfgrass. Preemergence 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 hat-1), siduron (13,500 g ha-1), and sulfentrazone (280 g ha-1). Treatments were replicated four times. Seedlings were counted at 35 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. Preemergence applications of pendimethalin, dithiopyr, methiozolin, and siduron were less effective against false-green kyllinga than smooth crabgrass at the 10% rate in New Jersey. Except for corn gluten meal and siduron, all herbicides completely controlled false-green kyllinga at the 100% rate in New Jersey. In Indiana, data were pooled across herbicide rate, and only pendimethalin was less effective against false-green kyllinga than smooth crabgrass although. Oxadiazon, dimethenamid, and bensulide were similarly effective against false-green kyllinga and smooth crabgrass at both locations. Corn gluten meal provided no crabgrass or false-green kyllinga control at either location."
