| Abstract/Contents: | "Greenhouse trials were conducted to evaluate gramincidal resistance of selected ornamental grasses. Blue fescue cultivars `Blue Glow', `Sea Urchin', `Spring Blue', and `Superba' were resistant to 1x (medium use rate) and 2x rates of fenoxaprop, fluazifop-P, quizalofop, and sethoxydim, whereas fountain grass, ravenna grass, and switchgrass were sensitive. Minor (less than 20%) visible phytotoxicity was observed on some fescues treated with the rate of fluazifop-P at 14 but not at 69 days after treatment (DAT). Fountain grass, ravenna grass, and switchgrass exhibited severe (greater than 70%) phytotoxicity from all herbicides 69 DAT. Mortality of non-fescues ranged from 55% (fountain grass) to 96% (ravenna grass)." |
