  • Herbicidal cyanofluorophenoxyphenoxyalkanoic acids and derivatives thereof
    Patent number: 4980494
    Abstract: Novel 2-(4-(2'-fluoro-4'-cyanophenoxy)-phenoxy)alkanoic acids and agriculturally acceptable derivatives thereof are selective postemergent herbicides for the control of grassy weeds in valuable crops. The novel herbicides are surprisingly selective, i.e., exhibit little or no phytotoxic effects, to wheat, barley and especially rice at concentrations that control undesired weed grasses.
    Type: Grant
    Filed: December 8, 1989
    Date of Patent: December 25, 1990
    Assignee: The Dow Chemical Company
    Inventors: R. Garth Pews, Lucinda A. Jackson, Chrislyn M. Carson

  • Grain selective herbicides
    Patent number: 4888041
    Abstract: Certain 5-(substituted phenoxy and substituted 2-pyridinyloxy)-3-methylbenzisoxazoles are selective herbicides for use in grain crops. The control of weeds in rice by the post-emergence application of 5-(2-chloro-4-(trifluoromethyl)phenoxy)-3-methylbenzisoxazole is exemplary. The pyridinyloxy substituted compounds are novel.
