Novel fluorophenoxyphenoxypropionates and derivatives thereof possess herbicidal activity selectively in the presence of broadleaf crops. Preemergent and postemergent applications are contemplated.

Fluorophenoxyphenoxypropionates and derivatives thereof

Novel intermediates useful in the preparation of fluorophenoxyphenoxypropionates and derivatives thereof which possess herbicidal activity selectively in the presence of broadleaf crops.

Novel compounds, e.g., N-methanesulfonyl 2-((5-(3-fluoro-5-(trifluoromethyl)-2-pyridinyl)oxy)-2-nitro-5-phenoxy)pro pionamide are selective herbicides useful for controlling weeds in valuable crops.

2-[16-(3-fluoro-5-trifluoromethyl-pyridinyl-2-oxy)-3-nitro-phenoxy]-pro

Less damage to soybeans occur when the combination of bentazon and a 3-substituted-pyridyloxy(or thio)phenoxy alkanoate herbicide is applied thereto, in comparison to the combination of bentazon and a 3-unsubstituted pyridyloxy(or thio)phenoxy alkanoate herbicide.

Selective, broadspectrum weed control in soybeans

Novel compounds having a pyridinyl radical positioned adjacent to the propanoic acid portion, e.g., ethyl 2-((6-(2-chloro-4-(trifluoromethyl)-phenoxy)-3-nitro-2-pyridinyl)oxy)propi onate, which are selective herbicides useful for controlling weeds in valuable crops.
