| Abstract/Contents: | "Many farmers who grow quality bermudagrass hay consider ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) to be weeds. Our standard recommendation for control of these species is glyphosate applied while the bermudagrass is dormant. We conducted three trials during 2006 and 2007 to evaluate glyphosate and other herbicides for the control tall fescue and ryegrass. These trials were prompted, in part, by farmer reports that glyphosate, applied during late winter or early spring, is ineffective for ryegrass control. In our trials, glyphosate at 0.75 lb ae/A was the most effective treatment for ryegrass control. Control ranged from 93% for a January 10, 2006 application to 100% for glyphosate applied March 2, 2007. Glyphosate applied November 11, 2006 at 0.28 lb ae/A provided 90% ryegrass control. Diuron at 1.5, nicosulfuron at 0.063, metsulfuron at 0.19 and chlorsulfuron at 0.023 lb ai/A were ineffective for ryegrass control. Tank mixing nicosulfuron or diuron with glyphosate reduced ryegrass control significantly. Tank mixes with metsulfuron and chlorsulfuron did not reduce or enhance glyphosate performance. The fescue control trial was conducted in dormant, common bermudagrass. Herbicides were sprayed on December 15, 2006 and evaluated on December 18, 2007. Treatments that provided 90% control or greater were glyphosate + imazapic + sulfometuron (0.38 + 0.19 + 0.023 lb ai/A), glyphosate + imazapic (0.75 + 0.19 lb ai/A), glyphosate + flazasulfuron (0.38 + .038 lb ai/A), and glyphosate + sulfometuron (0.38 + 0.094 lb ai/A). A tank mix of diuron plus glyphosate (0.38 + 1.5 lb ai/A) was completely ineffective for tall fescue control. Glyphosate + sulfometuron (0.38 + 0.047 lb ai/A) and glyphosate + sulfometuron (0.38 + 0.023 lb ai/A) resulted in 80 and 50% tall fescue control respectively." |
