| Abstract/Contents: | "Winter annual weeds can reduce the aesthetics of non-overseeded dormant bermudagrass. These weeds can proliferate while the bermudagrass is defoliated and not competing. The green color of these weeds creates an unsightly contrast with the brown turf. A study was conducted to examine the effectiveness of using post-emergence herbicides for control ofannualbluegrass [of annual bluegrass], mouseear chickweed, parsley-piert, and cudweed in dormant bermudagrass turf. The study was conducted on a golf course driving range in Pendleton, SC in 1999. Seventeen treatments were applied in a randomized complete block replicated 4 times. Plot size was 5 ft ' 10 ft. Treatments were applied using a CO2 backpack sprayer calibrated at 30 gal/A and 8003 flat fan tips. Treatments included a control, Atrazine 4L (atrazine), Reward (diquat) + Optima (adjuvant), Envoy (clethodim) + Dash (crop oil), Envoy + Optima, Envoy + Reward + Optima at three rates, Roundup Pro (glyphosate), Finale (glufosinate), Roundup Pro + Reward, Roundup Pro + Envoy, Roudnup pro [Pro] + Finale, Finale + Envoy + Optima, Kerb (pronamide), Image (imazaquin), and Metsulfuron. Treatments were applied on 5 February 1999. Visual control ratings were taken starting 3 days after treatment and weekly until seven weeks after application. Weed control ratings were based on a scale of0 [of 0] to 100% with 0 representing no control and 100 representing complete control. Bermudagrass was rated at the conclusion of this study to determine if the treatments delayed green-up. When rated 7 weeks after treatment, Envoy + Reward at all three rates, Finale, Finale + Roundup Pro, and Finale + Envoy provided > 90% control of annual bluegrass. Atrazine, Roundup Pro, and Roundup Pro + Envoy provided 70 - 89% control of annual bluegrass. Atrazine, Roundup Pro, Finale, Roundup Pro + Envoy, and Finale + Roundup Pro provided > 90% control of mouseear chickweed, while Roundup Pro + Reward and Finale + Envoy provided 70 - 89% control. Atrazine and Finale provided > 90% control of parsley-piert, while Finale + Roundup Pro provided 70 - 89% control. Roundup Pro, Finale, Roundup Pro + Envoy, Finale + Roundup Pro, and Finale + Envoy provided > 90% control of cudweed. When compared to the control, none of the treatments hindered bermudagrass green-up." |
