This invention relates to certain herbicidally active substituted diphenyl ether oxime derivatives, herbicidal compositions of the same and the use thereof for preemergence and postemergence control of noxious plants, i.e., weeds.

Herbicidally active substituted diphenyl ether oxime derivatives

This invention relates to the use of certain diphenyl ether oxime derivatives as pre-harvest crop defoliants.

Defoliant method

Disclosed are certain herbicidally active quinoline or quinoxaline acetophenone oxime derivatives, herbicidal compositions containing these compounds and the use of such compounds to control the growth of noxious plants, i.e., weeds.

Herbicidally active quinoline or quinoxaline acetophenone oxime

Aldoxime or ketoxime-O-alkanoic acid is prepared by transoximation of an aldehyde or ketone, the reaction being conducted in a liquid phase at a pressure below one atmosphere. Conversion of the aldoxime or ketoxime-O-alkanoic acid to the ester or salt form is also described.

Method for preparing aldoxime or ketoxime-O-alkanoic acid

This invention relates to certain herbicidally active substituted diphenyl ether acetals or ketals, herbicidal compositions of the same and the use thereof for preemergence postemergence control of noxious plants, i.e., weeds.

Herbicidally active substituted diphenyl ether acetals or ketals

Disclosed are certain herbicidally active benzoxazolyloxy benzoate derivatives, herbicidal compositions containing these compounds and the use of such compounds to control the growth of noxious plants, i.e., weeds.

Herbicidally active benzoxazolyloxy benzoate derivatives

Disclosed are certain herbicidally active quinoline or quinoxaline benzoate derivatives, herbicidal compositions containing these compounds and the use of such compounds to control the growth of noxious plants, i.e., weeds.

Herbicidally active quinoline or quinoxaline benzoate derivatives

Disclosed are certain herbicidally active benzoxazolyl acetophenone oxime derivatives, herbicidal compositions containing these compounds and the use of such compounds to control the growth of noxious plants, i.e., weeds.

Herbicidally active benzoxazolyl acetophenone oxime derivatives

Compounds, such as 5-(2-chloro-4-trifluoromethylphenoxy)-2-nitroacetophenone oxime-O-(acetic acid, methyl ester) and 5-(2-chloro-4-trifluoromethylphenoxy)-2-chloroacetophenone oxime-O-(acetic acid, methyl ester), are useful for postemergence and preemergence control of weeds, and are represented by Formula I of the application.

4-Trifluoromethylphenoxy-benzaldoximes

Disclosed are compounds such as 5-(2-chloro-4-trifluoromethylphenoxy)-2-nitroacetophenone oxime-O-methyl ether, and the method of controlling weeds, such as wild oats with the compounds.
