    摘要: 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.

    摘要: 5-Alkyl-1-(2-pyridinyl)-1H-1,2,4-triazol-3-ols are prepared in good yield by reacting an appropriate 1-acyl-1-(2-pyridinyl)-semicarbazide with a base in the presence of a non-nucleophilic solvent. The compounds so prepared are intermediates used in the preparation of insecticides. The starting semicarbazide materials are novel compounds.
