View Patent ↗The present invention relates to the use of phosphated 2-propylheptanol, phosphated 2-proyplheptanol alkoxylate and/or mixtures thereof in agricultural formulations. The invention also relates to agricultural formulations comprising the aforementioned adjuvants, and to methods of treating a plant with the agricultural formulations of the invention.
1. An agricultural formulation comprising at least one agricultural active, and at least one agricultural adjuvant, wherein the adjuvant comprises at least one phosphated 2-propylheptanol alkoxylate.
2. The formulation of claim 1 wherein the phosphated 2-propylheptanol alkoxylate on average comprises 1 to 20 ethyleneoxy units and 0-3 propyleneoxy and/or butyleneoxy units.
3. The formulation of claim 1 wherein the phosphated 2-propylheptanol alkoxylate is selected from the group consisting of:
(i) compounds of formula
wherein M is H, a monovalent metal ion or R 1 R 2 R 3 R 4 N + , where R 1 , R 2 , R 3 , and R 4 are H, an alkyl group with 1-4 carbon atoms or —CH 2 CH 2 OH, and c is a number 1-20;
(ii) compounds of formula
wherein n is 1-3 and M and c are as defined above;
(iii) compounds of formula
wherein M and c are as defined above;
(iv) compounds of formula
wherein M and c are as defined above; and
(v) mixtures thereof.
4. The formulation of claim 1 wherein the phosphated 2-propylheptanol alkoxylate comprises 2 to 4 ethyleneoxy units.
5. The formulation of claim 4 wherein the phosphated alkoxylate is a compound of formula
wherein M is H, a monovalent metal ion or R 1 R 2 R 3 R 4 N + , where R 1 , R 2 , R 3 , and R 4 are H, an alkyl group with 1-4 carbon atoms or —CH 2 CH 2 OH, and c is a number 2-4.
6. The formulation of claim 1 comprising 0.1-30% by weight of the adjuvant, wherein the phosphated 2-propylheptanol alkoxylate on average comprises 1 to 20 ethyleneoxy units and 0-3 propyleneoxy units.
7. The formulation of claim 6 , wherein the adjuvant is a phosphated 2-propylheptanol alkoxylate comprising 2-4 ethyleneoxy units.
8. The formulation of claim 1 wherein the adjuvant comprises a mixture of at least one phosphated 2-propylheptanol alkoxylate with at least one phosphated 2-propylheptanol, wherein the phosphated 2-propylheptanol alkoxylate is present in an amount of at least 60% by weight of the adjuvant mixture.
9. The formulation of claim 1 wherein the adjuvant is a dispersant, emulsifier, hydrotrope, wetting agent, and/or compatibility agent.
10. The formulation of claim 1 wherein the agricultural active is a herbicide, fungicide, insecticide, plant growth regulator, or mixtures thereof.
11. An adjuvant for agricultural formulations, wherein the adjuvant comprises at least one phosphated 2-propylheptanol alkoxylate.
12. The adjuvant of claim 11 wherein the phosphated 2-propylheptanol alkoxylate on average comprises 1 to 20 ethyleneoxy units and 0-3 propyleneoxy and/or butyleneoxy units.
13. The adjuvant of claim 11 wherein the phosphated 2-propylheptanol alkoxylate is selected from the group consisting of:
(i) compounds of formula
wherein M is H, a monovalent metal ion or R 1 R 2 R 3 R 4 N + , where R 1 , R 2 , R 3 , and R 4 are H, an alkyl group with 1-4 carbon atoms or —CH 2 CH 2 OH, and c is a number 1-20;
(ii) compounds of formula
wherein n is 1-3 and M and c are as defined above;
(iii) compounds of formula
wherein M and c are as defined above;
(iv) compounds of formula
wherein M and c are as defined above; and
(v) mixtures thereof.
14. The adjuvant of claim 11 wherein the phosphated 2-propylheptanol alkoxylate comprises 2 to 4 ethyleneoxy units.
15. The adjuvant of claim 14 wherein the phosphated 2-propylheptanol alkoxylate is a compound of formula
wherein M is H, a monovalent metal ion or R 1 R 2 R 3 R 4 N + , where R 1 , R 2 , R 3 , and R 4 are H, an alkyl group with 1-4 carbon atoms or —CH 2 CH 2 OH, and c is a number 2-4.
16. A method of treating plants which comprises contacting the plants with an agriculturally effective amount of the agricultural formulation of claim 1 .
