Abstract

A liquid phytoactive composition comprising (a) an N-phosphonomethyl-N -carboxymethyl compound; (b) one or more liquid surfactants; (c) a dispersing medium for said N-phosphonomethyl-N-carboxymethyl compound; and (d) inert adjuvants therefor.

Claims

1. A liquid phytoactive composition comprising:

(a) an herbicidally effective, agriculturally acceptable salt of an N-phosphonomethyl-N-carboxymethyl compound;

(b) one or more liquid nonionic alkyl polyglycoside surfactants;

(c) a dispersing medium selected from the group consisting of water and polar organic solvents for said N-phosphonomethyl-N-carboxymethyl compound; and

(d) an insert adjuvant.

2. A liquid phytoactive composition in the form of a liquid concentrate comprising:

(a) from about 10 to about 70 weight percent of an herbicidally effective, agriculturally acceptable salt of an N-phosphonomethyl-N-carboxymethyl compound;

(b) from about 40 weight percent of one or more water-soluble non-irritating, non-toxic liquid nonionic alkyl polyglycoside surfactants;

(c) from about 10 to about 40 weight percent of a dispersing medium selected from the group consisting of water and polar organic solvents for said N-phosphonomethyl-N-carboxymethyl compound; and

(d) from about 0.5 to about 10 weight percent of inert adjuvants.

3. A composition according to claim 2 wherein the N-phosphonomethyl-N-carboxymethyl compound is of the formula ##STR4## and wherein M is independently selected from hydrogen and agriculturally acceptable salt-forming moieties.

4. A composition according to claim 3 wherein at least one M is selected from an agriculturally acceptable salt-forming moiety.

5. The composition of claim 2 wherein the N-phosphonomethyl-N-carboxymethyl compound is N-phosphonomethylglycine.

6. The composition of claim 2 wherein the N-phosphonomethyl-N-carboxymethyl compound is the trimethylsulfonium salt of N-phosphonomethylglycine.

7. The composition of claim 2 wherein the N-phosphonomethyl-N-carboxymethyl compound is the isopropylamine salt of N-phosphonomethylglycine.

8. The composition of claim 2 wherein the N-phosphonomethyl-N-carboxymethyl compound is the sodium salt of N-phosphonamethylglycine.

9. The composition of claim 2 wherein the N-phosphonomethyl-N-carboxymethyl compound is the ammonium salt of N-phosphonamethylglycine.

10. The composition of claim 2 wherein the N-phosphonomethyl-N-carboxymethyl compound is the magnesium salt of N-phosphonomethylglycine.

11. The composition of claim 2 wherein the surfactant is a mixed alcohol glucoside.

12. The composition of claim 2 wherein (d) contains one or more of an anti-foaming agent, a heat stabilizing agent and an ultraviolet absorber.
