Abstract

The invention relates to a non-aqueous, emulsifiable and pourable concentrate formulation comprising: (a) at least 20% by weight of at least one non-ionic surfactant chosen from polyethylene glycol esters of fatty acids surfactants, relative to the total weight of the concentrate formulation; (b) a liquid medium wholly or partly formed from at least one non esterified vegetable oil or mixtures thereof; (c) at least one phyllosilicate, said phyllosilicate being present in a content of less than or equal to 5% by weight relative to the total weight of the concentrate formulation; and (d) at least one activator of said phyllosilicate. The invention also relates to the use of such a concentrate formulation for preparing a liquid aqueous emulsion, a suspoemulsion or an agricultural oil dispersion.

Claims

1-10. -10:

(canceled)

11. A non-aqueous, emulsifiable, and pourable concentrate formulation comprising:

(a) at least 20% by weight of at least one non-ionic surfactant selected from polyethylene glycol esters of fatty acids surfactants, relative to a total weight of the concentrate formulation;

(b) a liquid medium wholly or partly formed from at least one non-esterified vegetable oil or mixtures thereof;

(c) at least one phyllosilicate, said phyllosilicate being present in a content of less than or equal to 5% by weight, relative to the total weight of the concentrate formulation; and

(d) at least one activator of said phyllosilicate.

12. The concentrate formulation according to claim 11, wherein components (a) and (b) are present in a weight ratio (a)/(b) ranging from 0.1 to 4.

13. The concentrate formulation according to claim 11, comprising at least:

(a) 20 to 60% by weight of the polyethylene glycol esters of fatty acids surfactants;

(b) 20 to 80% by weight of the non-esterified vegetable oil or mixtures thereof;

(c) 1 to 5% by weight of the phyllosilicate; and

(d) 0.3 to 3% by weight of the activator of said phyllosilicate.

14. The concentrate formulation according to claim 11 further comprising at least one ingredient selected from salts, hydrocolloids, and mixtures thereof.

15. A liquid aqueous emulsion or a suspoemulsion comprising the concentrate formulation of claim 11.

16. An agricultural oil dispersion comprising the concentrate formulation of claim 11.

21. A method of preventing and/or combating infestation of plants by pests and/or of regulating plant growth comprising the application on said plant or locus of a spray mixture obtained by adding at least one agricultural active material and water to a concentrate formulation according to claim 11.

22. The concentrate formulation according to claim 12, wherein the weight ratio (a)/(b) ranges from 0.25 to 1.25.

23. The concentrate formulation according to claim 13, wherein the phyllosilicate is modified hectorite, and the activator of said phyllosilicate is propylene carbonate.

24. The concentrate formulation according to claim 14, wherein the salt is sodium carbonate, sodium bicarbonate, ammonium sulfate, or mixtures thereof, and the hydrocolloid is a guar.

17. An emulsifiable and stable agricultural oil dispersion comprising:

(a) at least one polyethylene glycol ester of fatty acid surfactant as non-ionic surfactant;

(b) a liquid medium wholly or partly formed from at least one non-esterified vegetable oil or mixtures thereof;

(c) at least one phyllosilicate;

(d) at least one activator of said phyllosilicate; and

(e) at least one agricultural active material,

wherein components (a) and (b) are present in a weight ratio (a)/(b) ranging from 0.1 to 4.

18. A method for making the agricultural oil dispersion according to claim 17, comprising the step of mixing the at least one agricultural active material with a concentrate formulation comprising:

(a) the at least one polyethylene glycol ester of fatty acid surfactant as non-ionic surfactant;

(b) the liquid medium wholly or partly formed from at least one non-esterified vegetable oil or mixtures thereof;

(c) the at least one phyllosilicate; and

(d) the at least one activator of said phyllosilicate.

19. A liquid agricultural aqueous emulsion convenient for spraying comprising the agricultural oil dispersion according to claim 17.

20. A method of preventing and/or combating infestation of plants by pests and/or of regulating plant growth comprising the application on said plant or locus of a spray mixture obtained by diluting with water an agricultural oil dispersion according to claim 17.

25. The emulsifiable and stable agricultural oil dispersion of claim 17, wherein the weight ratio (a)/(b) ranges from 0.25 to 1.25.
