Abstract
A herbicidal composition is provided which comprises: an aqueous solution of a herbicidally acceptable salt of N-phosphonomethylglycine; a quaternary ammonium compound represented by the formula ##STR1## wherein each A represents an alkylene group having 2 or 3 carbon atoms, R.sup.1 and R.sup.2 are each independently an alkyl or alkanol group having from 1 to 3 carbon atoms; R.sup.3 is an alkyl group having from 1 to 3 carbon atoms or a group having the formula (AO).sub.m --H; n (in a compound in which R.sup.3 is an alkyl group) or n+m (in a compound in which R.sup.3 is a group having the formula (AO).sub.m --H), has a value of from 2 to 15; and X.sup.- is a halide or phosphate; and a glycol selected from the group consisting of propylene glycol, and polypropylene glycol having an average molecular weight up to about 1000; wherein the weight ratio of N-phosphonomethylglycine to the quaternary ammonium compound is between about 1:5 to about 5:1; and the weight ratio of glycol to the quaternary ammonium compound is between about 1:40 and about 1:2 at a pH between pH 4 and pH 7 to provide a clear solution.
