Abstract

Herbicidally active compositions, which comprise 4-amino-3,6-dichloropyridine-2-carboxylic acid (herbicide A) and at least one herbicide B from the group of the lipid biosynthesis inhibitors, a method for controlling undesirable vegetation, their use for controlling undesirable vegetation, and formulations comprising such compositions.

Claims

1-15. -15. (canceled)

16. A herbicidal composition comprising:

a) a herbicide A which is 4-amino-3,6-dichloropyridine-2-carboxylic acid; and

b) at least one herbicide B from the group of the lipid biosynthesis inhibitors.

17. The composition of claim 16, wherein the herbicide B is selected from the group consisting of the acetamides, oxyacetamides, chloroacetanilides, thiocarbamates, and benzofuranes and their environmentally compatible salts.

18. The composition of claim 16, wherein the herbicide B comprises at least one chloroacetanilide which is selected from the group consisting of dimethenamid, dimethenamid-P, S-dimethenamid, acetochlor, alachlor, butachlor, butenachlor, diethatylethyl, dimethachlor, metazachlor, metolachlor, S-metolachlor, pretilachlor, propachlor, prynachlor, terbuchlor, thenylchlor and xylachlor.

19. The composition of claim 16, wherein the herbicide B comprises at least one oxyacetamide which is selected from the group consisting of anilofos, mefenacet, and flufenacet.

20. The composition of claim 16, additionally containing a further herbicide.

21. The composition of claim 16, additionally containing a safener.

22. The composition of claim 16, containing no safener.

23. The composition of claim 16, wherein the relative amount of herbicide A to the at least one herbicide B is in synergistically effective amounts.

24. The composition of claim 16, wherein the relative amount of herbicide A to the at least one herbicide B is from 500:

1 to 1;

500.

25. A method for controlling undesirable vegetation, which comprises allowing the composition of claim 16 to act on plants to be controlled or their habitat.

26. A method for controlling undesired vegetation, comprising applying the composition of claim 16 before, during and/or after the emergence of the undesirable plants;

the herbicides A and B being applied simultaneously or in succession.

27. A herbicide formulation comprising the composition of claim 16 and further comprising at least one solid or liquid carrier.

28. A method for controlling undesirable vegetation in crop plants comprising allowing the composition of claim 16 to act on the undesirable vegetation or their habitat before, during and/or after the emergence of the undesirable plants.

29. The method of claim 28, wherein the crops are crops of wheat, barley, rye, triticale, durum, rice, corn, sugarcane, sorghum, soybean, pulse crops, peanut, sunflower, sugarbeet, potato, cotton, brassica crops, turf, grapes, pomefruit, stonefruit, citrus, coffee, pistachio, garden ornamentals, bulb ornamentals, conifers and deciduous trees.

30. The method of claim 28, wherein the crop plants are resistant to AHAS inhibitor herbicides.

31. The method of claim 28, wherein the herbicides A and B are applied simultaneously or in succession.
