Abstract

The invention relates to an herbicidal composition comprising from about 30 to about 70% by weight of the composition, of at least one dinitroaniline herbicide; an organic solvent having a flash point greater than 60.5° C.; and acetophenone in amount in the range from 5-25% by weight. The invention also relates to a method of controlling weeds using the composition.

Claims

1. A herbicidal composition comprising:

(i) from about 30 to about 70% by weight of the composition, of at least one dinitroaniline herbicide;

(ii) an organic solvent having a flash point of greater than 60.5°

C.; and

(iii) acetophenone in amount in the range of from 5 to 25% by weight.

2. A composition according to claim 1 wherein the composition does not give rise to crystalline precipitates upon storage for at least 48 hours at 0°

C.

3. A composition according to claim 1 comprising from about 5 to about 20% by weight of the composition, of acetophenone.

4. A composition according to claim 1 comprising from about 8 to about 17% by weight of the composition, of acetophenone.

5. A composition according to claim 1 comprising from about 35 to about 65% by weight of the composition, of said at least one dinitroaniline and wherein said at least one dinitroaniline is selected from the group consisting of trifluralin, pendimethalin and ethalfluralin.

6. A composition according to claim 5 comprising from about 37 to about 65% by weight of the composition, of trifluralin.

7. A composition according to claim 6 comprising from about 40 to about 65% by weight of the total composition of trifluralin.

8. A composition according to claim 1 wherein the composition further comprises from about 0.5 to about 20% (w/w) of at least one oil-in-water emulsifier adapted to provide an emulsion on dilution of the composition with water.

9. A composition according to claim 8 wherein oil-in-water emulsifier comprises a phosphate ester surfactant.

10. A composition according to claim 9 comprising from about 1 to about 10% (w/w) of a phosphate ester surfactant.

11. A composition according to claim 9 wherein the surfactant includes a phosphorylated alcohol ethoxylate surfactant.

12. A composition according to claim 1 wherein the composition is an emulsifiable concentrate adapted to form an oil-in-water emulsion on dilution with water.

13. A composition according to claim 1 wherein the organic solvent comprises alkyl benzenes.

14. A composition according to claim 1 wherein the solvent component including the co-solvent comprises at least 30% by weight of the solvent component of alkyl benzenes.

15. A composition according to claim 12 wherein the composition is stable when diluted with a liquid fertilizer prior to use.

16. A composition according to claim 15 wherein the composition is diluted prior to use with a liquid fertilizer comprising at least one of UAN and UAS.

17. A method of controlling weeds comprising diluting a dinitroaniline concentrate according to claim 1 and applying the diluted concentrate at a rate of the dinitroaniline component sufficient to provide pre-emergent weed control.
