NUEVOS ACIDOS 2-(4-(2''-FLUORO-4''-CIANOFENOXY)FENOXY)ALKANOICO Y DERIVADOS DE LLO ACEPTABLES AGRICOLAMENTE SON HEBRICIDAL POS EMERGENTES SELECTIVOS PARA EL CONTROL DE MALAS HIERBAS EN CULTIVOS VALIDOS. LOS NUEVOS HERBICIDAS SON SORPRENDENTEMENTE SELECTIVOS, POR EJEMPLO EXHIBE EFECTOS PEQUEÑAS O NO FITOTOXINAS, AL TRIGO, LA CEBADA Y ESPECIALMENTE ARROZ EN CONCENTRACIONES QUE CONTROLA LAS MALAS HIERBAS NO DESEADAS. Novel 2-(4-(2 min -fluoro-4 min -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.
