Abstract

The present invention refers to an aqueous composition comprising prothioconazole, optionally chlorothalonil, and at least one sulfonate surfactant, said composition having a pH<7. The present invention also refers to a production process of said composition, and to the use of the composition in the treatment and/or the prevention of fungal infections in plants.

Claims (13)

1 . An aqueous composition comprising prothioconazole, and at least one sulfonate surfactant, said composition having a pH between 2 and 3.5, said composition further comprising at least one acid selected from sulfuric acid, phosphoric acid, hydrochloric acid, citric acid and mixture thereof, wherein said at least one sulfonate surfactant is a mixture comprising methylnaphthalenesulfate surfactant and lignosulfonate surfactant, wherein the total amount by weight of sulfonate surfactants is from 2% to 15%.

2 . The composition according to claim 1 , wherein the amount by weight of said prothioconazole is between 1% and 50.

3 . The composition according to claim 1 , wherein the amount by weight of said at least one sulfonate surfactant is between 4% and 10%.

4 . The composition according to claim 1 , wherein the concentration of said prothioconazole is between 10 g/l and 600 g/l.

5 . The composition according to claim 1 , said composition being an aqueous suspension concentrate (SC).

6 . The composition according to claim 1 , further comprising one or more antifreezes, or one or more dispersants, or one or more defoamers, or one or more biocide agents, or one or more thickeners.

7 . A process for the preparation of a composition according to claim 1 , comprising a step of mixing prothioconazole-and at least one sulfonate surfactant, in water.

8 . The process according to claim 7 , further comprising a step of adding at least one acid selected from inorganic acids, organic acids and mixtures thereof.

9 . The process according to claim 7 , further comprising a step of micronizing said composition.

10 . The composition according to claim 1 , further comprising chlorothalonil.

11 . The process according to claim 7 , further comprising a step of mixing chlorothanil.

12 . The composition according to claim 10 , wherein the amount by weight of said chlorothalonil is between 1% and 55%.

13 . The composition according to claim 10 , wherein the concentration of said chlorothalonil is between 100 g/l and 700 g/l.
