Monoalkyl sulfosuccinates in pesticide formulations and applications
View Patent ↗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.
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.
