Liquid concentrated herbicidal microemulsion compositions comprising glyphosate and either oxyfluorfen or acifluorfen
First Claim
1. A stable aqueous-based liquid concentrate herbicidal composition having a separate phase in the form of a microemulsion or micellar solution comprising:
- a) at least 15% of a water soluble herbicidal salt of N-phosphonomethylglycine a.e. dissolved in said liquid;
b) a water-insoluble diphenylether herbicide selected from the group consisting of oxyfluorfen and acifluorfen dissolved in an inert organic solvent and suspended in the aqueous liquid, the ratio by weight of N-phosphonomethylglycine herbicide a.e. to the diphenylether herbicide being from abut 10;
1 to about 100;
1;
c) about 5 to about 25% by weight of a surfactant mixture of (i) an alkoxylated fatty amine surfactant and (ii) an alkoxylated quaternary ammonium salt surfactant;
d) about 1 to about 25% by weight of a compatibility agent selected from the group consisting of dipropylene glycol and diethylene glycol; and
e) the remainder water.

Abstract
There is disclosed a liquid concentrate herbicidal composition comprising:
at least 15% by weight based on the total composition of N-phosphonomethylglycine or of a salt thereof or of a mixture of salts thereof (calculated as acid equivalent);
a water-insoluble diphenyl ether type herbicide (oxyfluorfen or acifluorfen) in the ratio by weight of N-phosphonomethylglycine a.e. to diphenyl ether type herbicide of from about 10:1 to about 100:1;
about 5 to about 25% by weight of a surface active component comprising a mixture of an alkoxylated fatty amine with a surfactant chemically different from the alkoxylated fatty amine;
0 to about 10% by weight of solvent, the surface active component optionally with admixture of the solvent being capable of dissolving the diphenyl ether herbicide;
about 1 to about 25% by weight of a compatibility agent; and
water if necessary to total 100%.
