| Abstract/Contents: | "Twelve ornamental grasses from the genera Calamagrostis, Eragrostis, Eranthus, Miscanthus, Sorghastrum, Spartian, Panicum, and Pennisetum were evaluated for tolerance to the postemergence herbicides fenoxaprop-ethyl, fluazifop-P, and sethoxdim at 0.4 kg a.i./ha. Calamagrostis was uninjured by fenoxaprop-ethyl as measured by visual injury ratings, height, and foliage dry weight. Greenhouse studies evaluated the tolerance of three Calamagrostis leaf was reduced linearly with increasing herbicide rates each day after application. The highest rate (3.2 kg a.i./ha) reduced the leaf expansion rate by 1 day and all other rates by 3 days after treatment. Leaf expansion rate differed between Calmagrostis cultivars at different times after herbicide treatment. Dry weight of Calmamagrostis arundinacea 'Karl Foerster' was reduced at 4 weeks after treatment but not after 10 weeks of treatment. Chemical names used: (±)-ethyl 2-[4-[(6-chloro-2-benzoxazolyl)oxy]phenoxy]propanoate (fenoxaprop-ethyl); (R)-2-[4-[[5-trifluuoromethyl) -2-pyridinyl]oxy]phenoxy]propanoic acid (fluazifop-P); 2-[1-(ethoxy imino)butyl]-5-[2 (ethylithio)propyl-3-hydroxy-2-cyclohexen-1-one (sethoxydim)." |
