| Abstract/Contents: | "Golf course superintendents must constrain budgets in response to reduced revenue and increased costs of chemicals, fertilizer, fuel, and other inputs. Low-maintenance turf has been increasingly adopted in out-of-play areas on the golf course to combat these budget restraints. Reduced inputs, such as biannual mowing, has led to unique weed problems in low-maintenance turf areas. One of the most prominent broadleaf weeds to encroach is blackberry (Rubus spp.). Blackberry is tolerant to common 3-way herbicides used on golf courses for broadleaf weed control, but metsulfuron, fluroxypyr, triclopyr, and picloram have all been proven effective on blackberry species in pasture and native areas. Our study was initiated on June 17, 2015 at two sites including: one Alleghany blackberry (Rubus allegheniensis Porter) (ABB) control site at the Virginia Tech golf course and a hard-fine fescue (Festuca longifolia Thuill. 'Aurora Gold') tolerance site at the Glade Road Research Facility. Treatments were applied as follows: Applications were made with a CO2 powered boom sprayer calibrated to deliver 280 L ha-1, and the trial was formatted as a randomized complete block. Treatments included: triclopyr at 2.34 L ha-1, fluroxypyr at 2.92 L ha-1, metsulfuron at 35.0 and 70.0 g ha-1, triclopyr at 2.34 L ha-1 + metsulfuron at 35.0 g ha-1, fluroxypyr at 2.92 L ha-1 + metsulfuron at 35.0 g ha-1, penoxulam + sulfentrazone + dicamba + 2,4-D at 7.01 L ha-1, triclopyr + sulfrentrazone + 2,4-D + dicamba at 4.68 L ha-1, carfentrazone + 2,4-D + mecoprop + dicamba at 5.80 L ha-1, quinclorac + sulfentrazone 1.12 kg ha-1, 2,4-D + fluroxypyr + dicamba at 4.38 L ha-1, picloram + 2,4-D at 9.34 L ha-1, picloram + 2,4-D at 9.34 L ha-1 + metsulfuron at 35.0 g ha-1, and an untreated check for comparison. All metsulfuron containing treatments received 0.25 percent v/v of NIS. For the ABB control site, cover and control were rated every 2 weeks until 8 weeks after treatment (WAT), and then rated monthly until leaf drop. The fine fescue tolerance trial was rated for cover and injury every 2 weeks until turf had completely recovered from the treatments. Initial ABB cover ranged from 20 to 90 percent. At 4 WAIT, all treatments containing triclopyr and fluroxypyr controlled ABB 98 percent except for 2,4-D + fluroxypyr + dicamba which controlled ABB 88 percent. Triclopyr + sulfentrazone + 2,4-D + dicamba, carfentrazone + 2,4-D + mecoprop + dicamba, and picloram + 2,4-D + metsulfuron controlled ABB between 70 and 78 percent 4 WAIT. Treatments containing triclopyr, fluroxopyr, or metsulfuron controlled ABB better than other treatments at 8 WAIT. Triclopyr + metsulfuron, triclopyr alone, and fluroxypyr + metsulfuron controlled ABB at least 98 percent by season's end. Three and four-way herbicides like Speedzone had some of the fastest activity at 1 WAIT, but by 8 WAIT regrowth of ABB had reduce control to below 60 percent. No treatment caused unacceptable injury to fine fescue. Assessments will be made next summer to determine long-term ABB control by these treatments." |
