Novel 2,6-dihalogenated benzylidene amino-oxyacetic acid compounds and derivatives thereof, have been found to have exceptional herbicidal activity, particularly in regard to nutsedge control. The compounds have the general formula:- <CHEM> wherein X and Y are halogen; R1 is hydrogen or C1 to C7 alkyl; and R2 is selected from the group consisting of a carboxyl group, a metal salt of a carboxyl group, a C1 to C12 ester of a carboxy group, a C1 to C4 alkylamine salt of a carboxyl group, an amide of a carboxyl group, a hydrazid of a carboxyl group, and a cyano group; with the proviso that when R1 is methyl and when x and y are chlorine, R2 is not a carboxyl group. |
