The composition of the invention comprises a glyphosate herbicide and a quaternary ammonium compound the latter having the formula ##STR1## wherein --EO-- means an ethylene oxide radical and --PO-- means a propylene oxide radical, R.sup.1 and R.sup.2 are each independently an alkyl group having from 1 to 3 carbon atoms; R.sup.3 is an alkyl group having from 1 to 3 carbon atoms, a group having the formula (EO).sub.m --H or a group having the formula EO--(PO).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 EO--(PO).sub.m --H), has a value of from about 2 to about 20; and X.sup.- is a suitable anion.
