| Abstract/Contents: | "Field studies were conducted in 2009 to evaluate chemical mowing with herbicides at reduced rates alone and in mixture to tall fescue (Festuca arundinacea) in grape (Vitis spp.) row middles. Trial sites were established at the Highland Rim Research & Education Center and the Plateau Research & Education Center in Tennessee and an additional site was located at Three Sister's Vineyard & Winery in Georgia. All treatments were applied postemergence (POST) to tall fescue infested with weeds such as buckhorn plantain (Plantago lanceolata), dandelion, (Taraxacum officinale), and white clover (Trifolium repens) and all species were 2 to 9 cm in height at the time of application. Field plots were 3 by 6 meters and arranged in a randomized complete block design with three replications. Herbicide treatments in all three trials included: sethoxydim at 131 g ai/ha + carfentrazone at 9 g ai/ha, sethoxydim at 131 g ai/ha + carfentrazone at 18 g ai/ha, glyphosate at 110 g ai/ha + carfentrazone at 9 g ai/ha, glyphosate at 110 g ai/ha + carfentrazone at 18 g ai/ha, sethoxydim at 131 g ai/ha+ glyphosate at 110 g ai/ha, glyphosate at 110 g ai/ha, sethoxydim at 131 g ai/ha, carfentrazone at 9 g ai/ha, carfentrazone at 18 g ai/ha, glufosinate at 234 g ai/ha, glufosinate at 234 g ai/ha + sethoxydim at 131 g ai/ha, glufosinate at 234 g ai/ha + carfentrazone at 9 g ai/ha, and glufosinate at 234 g ai/ha + carfentrazone at 18 g ai/ha. All treatments were applied with a CO2 powered backpack sprayer calibrated to deliver 23 gal/A. All treatments contained crop oil concentrate at 1% v/v. Fescue suppression and weed control were evaluated 7, 14, 28, and 56 days after treatment (DAT). By 28 DAT, sethoxydim applied alone or in combinations with glufosinate, glyphosate or carfentrazone provided the greatest suppression of tall fescue (72 to 79%). Glyphosate and glufosinate alone and in combinations with carfentrazone provided 30 to 53 % suppression of tall fescue by 28 DAT. Carfentrazone alone did not provide adequate suppression of tall fescue. By 56 DAT, tall fescue was still suppressed with treatments containing glyphosate and or sethoxydim in comparison to the untreated control; however heights were greater than a commercially acceptable range (24-31 inches). In addition, no treatment evaluated in these studies provided sufficient control of buckhorn plantain, dandelion or white clover." |
