Claims

1. A composition for controlling unwanted vegetation, said composition comprising a glyphosate compound, a lipophilic fatty acid compound, and a surfactant, wherein the combined concentration of said glyphosate compound and said fatty acid compound is at least about 12% by weight.

2. The composition, according to claim 1, wherein the total concentration of the glyphosate compound and the fatty acid compound is between about 12% and about 60%

3 The composition, according to claim 2, wherein said surfactant is present at a concentration of between about 2% and about 20%.

4. The composition, according to claim 3, wherein said surfactant is of the nonylphenol ethoxylate class.

5. The composition, according to claim 4, wherem said surfactant has from about 5 moles to about 15 moles of ethoxylation.

6. The composition, according to claim 2, further compπsing a co-solvent at a concentration of between about 5% and about 30%.

7. The composition, according to claim 6, wherein said co-solvent is an alcohol having from about 1 to about 8 carbon atoms.

8. The composition, according to claim 1, wherem said glyphosate compound is the isopropyl amine salt.

9 The composition, according to claim 1, wherein said fatty acid compound has the following formula:
o
RιY1Y2CZR2XιX2
wherein Z = O, N, or S;
R[ = C5 to C12 saturated or unsaturated hydrocarbon, or an epoxide, or
cyclopropane thereof;
Yt = H, C1-C5 hydrocarbon, or hydroxyl at any position along R,;
Y2 = H, C1-C5 hydrocarbon, or hydroxyl at any position along R,;
R2 = H, Cl to CIO saturated or unsaturated hydrocarbon, or a salt- forming
moiety chosen from the group consisting of aliphatic amines which
form cationic aliphatic ammonium compounds;
X, = H, hydroxyl, or Cl to C3 hydrocarbon at any position along R2, and
X2 = H, hydroxyl, or Cl to C3 hydrocarbon at any position along R2, wherem if Z = N, then there are two R2 groups, and if the R2 groups are H, then there is no X, or X2 group.

10. The composition, according to claim 9, wherein said fatty acid compound is an ester or lipophilic amine denvative of a C9 to C12 fatty acid

11. The composition, according to claim 10, wherem said fatty acid compound is ethylene glycol pelargonate.

12. A process for prepaπng a concentrated composition for controlling unwanted vegetation, said process compπsing the steps of combining a glyphosate compound and a lipophilic fatty acid compound with a surfactant to form a concentrate compπsing between about 12% and about 60% of the fatty acid compound and the glyphosate compound.
