Wild Garlic (Allium vineale) a cool season perennial with slender, hollow cylindrical leaves, is widely distributed and makes for unsightly appearance in highly maintained turf areas. The purpose of this research was to investigate the use of various postemergence herbicides for wild garlic control. The research for this study was conducted over a two-year period, on a non-overseed bermudagrass golf course rough, located in Pendleton, SC. Plot size for each treatment measured 2.0 m by 3.0 m, replicated three times. Treatments were applied using a CO2 backpack sprayer calibrated at 20 GPA, at 30 p.s.i., with 8003 flat fan spray tips. Treatments for the study included: 2, 4-D Amine 4L at 1.0 (lb ai/a), Confront 3L at 0.75, Lontrel at 0.375, Manor 60 DF at 0.05, SpeedZone 2.2L at 1.1, Trimec Classic 2.72L at 1.36, Image 70 DG at 0.38, Turflon Ester 4EC at 1.0 and Monument 75WG at .03. All treatments received an Induce at 0.25% V/V. Treatments were applied in mid November of 2003 with a sequential application applied in mid February of 2004 for the first year. Treatments for the second year were applied in mid November of 2004 with a sequential application in mid February of 2005. Visual wild garlic control was evaluated throughout the study. Control was on a 0 – 100% scale where 0 = no control and 100 = complete control. In addition to control, bermudagrass turf quality was also rated on 1 – 9 scale were 1 = dead turf and 9 = best turf quality. Rating was based on turf color and density. Future research at Clemson University will be to look at various rates and timings of these postemergent herbicides. In addition, evaluate various other postemergent herbicides and combinations thereof for postemergence wild garlic control.
