ABSTRACT:
The present invention relates to a herbicidal composition comprising as the effective components at least one substituted acetanilide and at least one other specific herbicidal compound.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 3,965,139 and U.S. Pat. No. 4,001,325 disclose certain substituted acetanilide derivatives as active ingredients for herbicides. The compounds disclosed in these patents are useful as herbicides for controlling grass weeds and certain broadleaf weeds. However, many weeds are not controlled by these herbicides, thus limiting their use for practical weed control in important crops. It has been found that mixing the acetanilide compounds of the above patents with other herbicides produces practical combinations which give effective weed control. Furthermore, unexpected differences in crop safety were found in certain combinations, resulting in unpredicted, preferred combinations and less preferred combinations with reduced crop safety.
SUMMARY OF THE INVENTION
The present invention provides to a herbicidal composition comprising as the effective components
A) at least one substituted acetanilide derivative of the formula I:
wherein n is an integer of 1 or 2
R is H, halogen, C
1-4
alkyl or C
1-2
alkoxy
Q is cyanomethyl or propargyl
X is halogen; and
B) at least one compound selected from the group consisting of aryloxyalkanoic acids, aromatic carboxylic acids, ureas, triazines, anilides, hydroxybenzonitriles, quaternary ammonium salts, triketones, aryloxyphenoxypropionic acids, oximes, sulfonylureas, imidazolinones, dinitroanilines, chloroacetanilides, oxyacetamides, thiocarbamates, amides, semicarbazones and inhibitors of protoporphyrinogen oxidase that include diphenyl ethers, substituted uracils, N-phenylphthalimides, pyrazoles, triazolinones and triazolopyridinones.
DETAILED DESCRIPTION OF THE INVENTION
In the above definitions, the term halogen includes fluorine, chlorine, bromine, or iodine. The term alkyl includes straight chain or branched alkyls containing 1-4 carbon atoms.
