Halophenoxy benzamide herbicides

Abstract

2-Nitro-5-(halophenoxy)benzoic acids and esters, salts, amides, and acyl halides thereof comprise a class of compounds that are highly effective pre- and post-emergence herbicides.

What is claimed is: 
     
       1. An herbicidal compound having the formula: ##STR2## wherein X is halogen, n is 1 to 5, and R is amido, alkylamido .[.(C 1  --C 6 ).]. .Iadd.(C 1  --C 3 ).Iaddend., or dialkylamido .[.(C 1  --C 6 ).]. .Iadd.(C 2  --C 6 ).Iaddend.wherein each alkyl of the dialkylamido contains 1 to 3 carbon atoms. .[. 
     
     
       2.  A compound of claim 1, wherein said compound is N-methyl 2-nitro-5-(2',4'-dichlorophenoxy)benzamide..]. .[.3. A compound of claim 1, wherein said compound is N,N-dimethyl 
     
     
        2-nitro-5-(2',4'-dichlorophenoxy)benzamide..]. 4. A compound of claim 1, wherein said compound is N,N-dimethyl 2-nitro-5-(2',4',6'-trichlorophenoxy)benzamide. .[.5. A compound of claim 1, wherein said compound is N,N-dimethyl 2-nitro-5-(2',4'-dichloro-6'-fluorophenoxy)benzamide..]. .[.6. A compound of claim 1, wherein said compound is N-sec-butyl 
     
     
        2-nitro-5-(2',4'-dichloro-6'-fluorophenoxy)benzamide..]. 7. A compound of claim 1, wherein said compound is 2-nitro-5-(2',4',6'-trichlorophenoxy)benzamide.
