Abstract

The present invention relates to herbicidal compositions comprising an isoxazolo[5,4-b]pyridine and at least one further compound selected from herbicidally active compounds and, if desired, safeners. The present invention also relates to the use of such a composition for controlling unwanted vegetation and to a method for controlling unwanted vegetation, which comprises allowing a composition to act on plants, their seeds and/or their habitat.

First claim

What is claimed:

1. A herbicidal composition comprising:
as component A) an isoxazolo[5,4-b]pyridine compound of formula I

wherein the variables are as defined below:
R 1 is hydrogen;
R 2 is cyclopropyl; and
R 3 is cyclopropyl or an agriculturally useful salt thereof; and
as component B) at least one further herbicide selected from b3) photosynthesis inhibitors selected from the group consisting of paraquat, pentanochlor, propanil, bentazone, bromoxynil, phenmedipham, pyridate, atrazine, terbuthylazin, ametryne, metribuzin, hexazinone, amicarbazone, bromacil, chlorotoluron, diuron, and isoproturon;
wherein component A and component B are present in synergistically effective amounts and in a weight ratio of A:B from 75:1 to 1:75.

2. An agrochemical composition comprising the herbicidal composition of claim 1 , at least one inert liquid and/or solid carrier and, if desired, at least one further additive.

3. A method for controlling unwanted vegetation, comprising allowing the composition of claim 1 to act on plants, their seeds and/or their habitat.

4. The method of claim 3 , wherein the unwanted vegetation is controlled in a crop field where crop plants are cultivated.

5. The method of claim 4 , wherein the crop plants are selected from cereals, corn, soybean, rice, millet, oilseed rape, cotton, sugarcane, potatoes, legumes, turf and permanent crops.

6. The herbicidal composition of claim 1 , wherein the b3) photosynthesis inhibitors are selected from the group consisting of paraquat, bentazone, bromoxynil, atrazine, terbuthylazin, metribuzin, amicarbazone, and chlorotoluron.

7. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is paraquat.

8. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is bentazone.

9. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is bromoxynil.

10. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is atrazine.

11. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is terbuthylazin.

12. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is metribuzin.

13. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is amicarbazone.

14. The herbicidal composition of claim 6 , wherein the b3) photosynthesis inhibitor is chlorotoluron.
