Golf course putting greens are composed of a turfgrass monoculture. In the southeastern United States, bentgrass ( Agrostis palustris Huds.) and hybrid bermudagrass [ Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy] are the dominant

wastewater (recycled water) for landscape irrigation. Golf courses are the leading urban landscape users of recycled water. The total area of golf courses in the United States was 608,732 ha in 2007. It is estimated that during 2003 to 2005, 80% of maintained

The environmental impact of golf courses has been studied increasingly in recent years. King et al. (2007) studied storm runoff from a golf course in Texas and found that although nitrogen concentrations in runoff were not a concern, phosphorus

Based on a national survey, golf courses in the United States used 2.3 million acre-ft of irrigation water per year during 2004–05, with 12% of all golf facilities using recycled water as one of the water sources ( Throssell et al., 2009 ). Recycled

Bermudagrass ( Cynodon spp.) is the most important, widely adapted warm-season turfgrass and is commonly used in golf course putting greens in the transition zone. Many golf courses in this region are converting their putting greens from the cool

Many golf courses in the southwestern United States are transitioning to reuse water for irrigation purposes. In Las Vegas, NV, 30 of 53 golf courses now irrigate with reuse water. As communities grow in size, the amount of reuse water generated

Weeping lovegrass (Eragrostis curvula) is commonly used in native areas bordering golf courses in the Southeastern United States. These areas do not receive significant levels of maintenance, thus weed encroachment is a problem that can negatively impact the functional and aesthetic values of the golf course. The objectives of this study is to determine which selective postemergent herbicides labeled for use on golf courses can remove weeds from Weeping Lovegrass and to determine the level of phytotoxicity. Herbicides included monosodium methane arsenate (MSMA 6.0) applied at 3.0 lb/acre a.i., sulfosulfuron (Certainty) at 0.047 lb/acre a.i., metribuzin (Sencor 75 DF) at 0.5 lb/acre a.i., and imazaquin (Image 70 DG) at a rate of 0.5 lb/acre a.i.. Treatments were applied on July 20, 2004 to 9.6 × 9.6 plots arranged in a randomized complete block design (RCBD) using Teejet 8005 nozzles at 40 psi calibrated to deliver 40 ga/acre. Plots were monitored daily and data was collected 0, 7, 14, 21, 28, 35, and 42 DAT. Sulfosulfuron and MSMA provided the highest level of weed control 35 DAT. Metribuzin and imazaquin provided limited weed suppression compared to the control. Initial phytotoxic damage to the Lovegrass was observed in all herbicide treatments. The highest level of phytotoxic damage was observed in the MSMA and Metribuzin treatments; however there was no apparent damage at 42 DAT. Herbicide applications of sulfosulfuron and MSMA are effective in reducing weed populations with acceptable levels of phytotoxicity to the Lovegrass.
