Abstract

A herbicidal composition containing hexazinone and an alkylene carbonate.

Claims (24)

1. A herbicidal composition comprising hexazinone and an alkylene carbonate with the proviso that the composition does not contain a surfactant.

2. A composition as claimed in claim 1 , wherein the alkylene carbonate is propylene carbonate.

3. A composition as claimed in claim 1 , wherein the alkylene carbonate is ethylene carbonate.

4. A composition as claimed in claim 1 , wherein the alkylene carbonate is butylene carbonate.

5. A composition as claimed in claim 1 , wherein the ratio of hexaxinone to alkylene carbonate is at most 1:10.

6. A composition as claimed in claim 1 , wherein the ratio of hexaxinone to alkylene carbonate is at most 1:5.

7. A composition as claimed in claim 1 , wherein the ratio of hexaxinone to alkylene carbonate is at most 1:2.

8. A herbicidal composition as claimed in claim 1 , wherein the hexazinone comprises at least 5% by weight of the total composition.

9. A herbicidal composition as claimed in claim 1 , wherein the hexazinone comprises at least 10% by weight of the total composition.

10. A herbicidal composition as claimed in claim 1 , wherein the hexazinone comprises at least 15% by weight of the total composition.

11. A herbicidal composition as claimed in claim 1 , wherein the hexazinone comprises at least 20% by weight of the total composition.

12. A herbicidal composition as claimed in claim 1 , wherein the hexazinone comprises at least 25% by weight of the total composition.

13. A herbicidal composition as claimed in claim 1 , wherein the hexazinone comprises at least 30% by weight of the total composition.

14. A method comprising mixing the composition as claimed in claim 1 with water and spraying onto plant foliage.

15. The herbicidal composition as claimed in claim 1 , which further has no other solvent.

16. A herbicidal composition as claimed in claim 1 , which further comprises another solvent.

17. A herbicidal composition comprising hexazinone and a sufficient amount of alkylene carbonate to completely solubolize the hexazinone with the proviso that the composition does not contain a surfactant.

18. A herbicidal composition as claimed in claim 1 which further comprises another herbicide.

19. A herbicidal composition as claimed in claim 1 , wherein the composition does not contain a defoaming or foam breaking agent selected from the group consisting of perfluoroalkylphosphonic acid, perfiuoroalkylphosphinic acid and perfluoroaliphatic polymeric ester.

20. A herbicidal composition as claimed in claim 7 , wherein the hexazinone comprises at least 20% by weight of the total composition.

21. A herbicidal composition comprising hexazinone and an alkylene carbonate with the proviso that the composition does not form an emulsion.

22. The composition as claimed in claim 21 , wherein the ratio of hexaxinone to alkylene carbonate is at most 1:2.

23. The herbicidal composition as claimed in claim 22 , wherein the hexazinone comprises at least 30% by weight of the total composition.

24. A herbicidal composition comprising hexazinone and an alkylene carbonate with the proviso that the composition is water miscible.
