44 CUTS & CONTOURS Army Golf Courses Commit to Audubon Program Audubon International announced that all the golf courses in the U.S. Army's Program for Family and Morale, Welfare and Recreation (US Army MWR) will pursue environmental certification through the Audubon Cooperative Sanctuary Program (ACSP for Golf). The Army's MWR Program maintains and operates 45 separate golf courses around the globe for enjoyment by golfers of all levels. Army golf courses are found throughout the US (including Hawaii and Alaska) and overseas locations such as Japan, Korea, and Europe. The enrollment of the Army MWR golf facilities in the Audubon International program demonstrates the Army's continued pursuit of sustainability to enable its current and future missions, safeguard human health and the well-being of soldiers, families, and civilians, control costs protect the natural environment. The Army golf facilities function at high levels participation, accommodating nearly two million rounds of golf each year. www.auduboninternational.org Researchers Confirm First Herbicide- Resistant Annual Sedge in Turfgrass Researchers writing in the journal Weed Science say the effectiveness of acetolactate synthase (ALS) inhibitors used to control weeds in turfgrass is now being threatened. They have just confirmed an ALS-resistant biotype of annual sedge (Cyperus weed often found growing in lawns, golf courses, sod farms and similar turfgrass Resistance to ALS-inhibiting herbicides has increased exponentially over the in a wide variety of cropping systems. This is the first report of an ALS-resistant species in turfgrass, though, as well as the first report of ALS-resistant annual setting. The resistant biotype was found growing in bermudagrass in Georgia where the inhibitor halosulfuron had been used to the exclusion of other weed control techniques. "ALS inhibitors are valued in turf for their low use rates, broad spectrum control limited potential to injure turfgrass," said Patrick E. McCullough of the University Georgia, the lead researcher for the study. "To preserve the effectiveness ALS though, it is clear turfgrass managers need to adopt integrated weed management programs that can help them prevent the establishment and spread of ALS-resistant biotypes." www.wssa.net
