Abstract

The present invention comprises formulations for use as pesticides and their applications. The formulations include a monoalkylsulfosuccinnate as a hydrotrope. The pesticide may be a herbicide comprising glufosinate-ammonium.

First claim

We claim:

1. A pesticide formulation comprising a pesticide, an adjuvant and a monoalkyl sulfosuccinate hydrotrope having the structure:

where
R is a linear or branched alkyl group comprising 3-4 carbons;
X is O;
Y and Z, independently of one another, comprise H or —SO 3 M′ where M′=sodium, ammonium, potassium, or calcium, wherein at least one of Y and Z comprises —SO 3 M′; and
M is a sodium, ammonium, potassium, calcium, ethylamine, propylamine, isopropylamine, or alkanolamine;
wherein a weight ratio of pesticide to adjuvant is about 1:1 to about 1:5.

2. The pesticide formulation of claim 1 , wherein the monoalkyl sulfosuccinate hydrotrope has the structure

where R is a C3-C4 alkyl group, and M is a sodium, potassium, or ammonium ion.

3. The pesticide formulation of claim 1 wherein the pesticide is glufosinate-ammonium.

4. The pesticide formulation of claim 1 , wherein R is a linear or branched alkyl group comprising 4 carbons.

5. The pesticide formulation of claim 1 , wherein the hydrotrope is a sodium monobutylsulfosuccinate.

6. A method of providing pesticide protection to an agricultural crop comprising the step of applying the formulation of claim 1 to said crop.

7. The method of claim 6 wherein the pesticide is glufosinate-ammonium.

8. A pesticide formulation comprising a pesticide, an adjuvant and a monoalkyl sulfosuccinate hydrotrope having the structure:

where
R is a linear or branched alkyl group comprising 3-4 carbons;
X is O;
Y and Z, independently of one another, comprise: H, or —SO 3 M′ where M′=sodium, ammonium, potassium, or calcium, wherein at least one of Y and Z comprises —SO 3 M′; and
M is sodium, ammonium, potassium, calcium, ethylamine, propylamine, isopropylamine, or alkanolamine;
wherein the adjuvant comprises a sodium or ammonium salt of an alcohol ether sulfate; and
wherein a weight ratio of pesticide to adjuvant is about 1:1 to about 1:5.

9. The pesticide formulation of claim 8 , wherein the monoalkyl sulfosuccinate hydrotrope has the structure:

where R is a C3-C4 alkyl group, and M is a sodium, potassium, or ammonium ion.

10. The pesticide formulation of claim 8 , wherein R is a linear or branched alkyl group comprising 4 carbons.

11. The pesticide formulation of claim 8 , wherein the hydrotrope is a sodium monobutylsulfosuccinate.

12. A method of providing pesticide protection to an agricultural crop comprising the step of applying the formulation of claim 8 to said crop.

13. A pesticide formulation comprising a pesticide, an adjuvant and a monoalkyl sulfosuccinate hydrotrope having the structure:

where
R is a linear or branched alkyl group comprising 3-4 carbons;
X is O;
Y and Z, independently of one another, comprise H, or —SO 3 M′ where M′=sodium, ammonium, potassium, or calcium, wherein at least one of Y and Z comprises —SO 3 M′; and
M may be sodium, ammonium, potassium, calcium, ethylamine, propylamine, isopropylamine, or alkanolamine;
wherein the pesticide is glufosinate-ammonium;
wherein the adjuvant is a sodium or ammonium salt of an alcohol ether sulfate; and
wherein a weight ratio of pesticide to adjuvant is from about 1:1 to about 1:5.

14. The pesticide formulation of claim 13 , wherein the monoalkyl sulfosuccinate hydrotrope has the structure:

where R is a C3-C4 alkyl group, and M is a sodium, potassium, or ammonium ion.

15. The pesticide formulation of claim 13 , wherein R is a linear or branched alkyl group comprising 4 carbons.

16. The pesticide formulation of claim 13 , wherein the hydrotrope is a sodium monobutylsulfosuccinate.

17. A method of providing pesticide protection to an agricultural crop comprising the step of applying the formulation of claim 13 to said crop.
