Abstract
A herbicidal composition is provided which is substantially non-irritant to the eyes and which comprises a stable aqueous concentrate solution of one or more agriculturally acceptable salts-of N-phosphonomethylglycine and a surfactant represented by the formula ##STR1## wherein R is an alkyl group having from about 6 to about 14 carbon atoms, R.sup.1 is ethyl, propyl, or a mixture of ethyl and propyl, the sum of n and m is between about 5 and about 50, R.sup.2 is an alkyl group with 1-4 carbon atoms, X is an agriculturally acceptable anion, and the weight ratio of surfactant to N-phosphonomethylglycine (expressed as the acid equivalent) is between about 1:5 and about 5:1.
