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.
Novel 2-(4-(2'-氟-4'-氰基苯氧基)苯氧基)脂肪酸及其农业可接受的衍生物是一种选择性的后出苗除草剂,可用于控制有价值作物中的草本杂草。这种新型除草剂具有惊人的选择性,即在控制不受欢迎的杂草草本的浓度下,对小麦、大麦和尤其是水稻几乎不产生植物毒性作用。
