| Abstract/Contents: | "Field experiments were conducted from 2017 to 2018 to evaluate September applications of various herbicides for false-green kyllinga (Kyllinga gracillima; FGK) control in Lakewood, NJ at Woodlake Country Club and in Cape May Courthouse, NJ at Stone Harbor Golf Club. The Lakewood and Cape May Courthouse locations were maintained a golf course fairway and rough, respectively. Both sites consisted of >70% false-green kyllinga cover when the experiments were initiated in 2017. At the Cape May Courthouse site, treatments consisted of halosulfuron-methyl (70 g ha-1), imazosulfuron (420 g ha-1), pyrimisulfan (70 g ha-1), and sulfentrazone + carfentrazone (280 + 31 g ha-1) applied on 7 September 2017 and 27 June 2018 forming a four-by-two (herbicide-by-application timing) complete factorial treatment arrangement. At the Lakewood site the same herbicide treatments were applied on 14 September only forming a single-factor design. Treatments were arranged in a randomized complete block design with four replications and applied to 0.9 by 2.0 m plots. Sprayable treatments were applied using a CO2-powered single nozzle boom with 374 L ha-1 of water carrier though an AI9504EVS nozzle. Imazosulfuron and halosulfuron-methyl were applied with NIS at 0.25% v/v. Pyrimisulfan was a granular formulation (EH-1617) applied using a shaker jar in the absence of dew. False-green kyllinga control was evaluated visually on a 0 (i.e., no control) to 100 (i.e., complete control) percent scale relative to a nontreated control at both locations. A grid intersect count was conducted at the Cape May Courthouse location in October 2018. Data were analyzed using the Mixed procedure in SAS and Fishers Protected LSD (Ī±=0.05) was used to separate means. Imazosulfuron controlled FGK more than halosulfuron-methyl, pyrimisulfan, and sulfentrazone + carfentrazone in June 2018 at the Lakewood site. At the Cape May Courthouse location, June applications of imazosulfron and pyrimisulfan controlled FGK 98 and 56%, respectively, while September applications provided less (74 and 8%, respectively) control in October 2018 at 57 weeks after initial treatment. Halosulfuron and sulfentrazone + carfentrazone controlled FGK similarly (ā¤ 25%) regardless of application timing in October 2018 at Cape May Courthouse. These data indicate that September applications are less effective than June applications. Future research should determine whether September applications in combination with cool-season turfgrass interseeding are more effective than June applications." |
