Abstract

The present invention relates to herbicidally active compositions, which comprise 3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole [common name pyroxasulfone] and at least one herbicide B and at least one herbicide B which is selected from group consisting of synthetic auxins and auxin transport inhibitors.
The invention furthermore relates to a method for controlling undesirable vegetation, which comprises applying an herbicidal composition according to the present invention to the undesirable plants. Application can be done before, during and/or after, preferably during and/or after, the emergence of the undesirable plants. The herbicide A and the at least one herbicide B can be applied simultaneously or in succession.

First claim

We claim:

1. A synergistic herbicidal composition comprising:
a) a herbicide A which is 3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole;
and
b) a herbicide B which is selected from the group consisting of dicamba, its salts and its esters,
wherein the relative amount of herbicide A to herbicide B is 100:1 to 1:100.

2. The composition as claimed in claim 1 , containing no safener.

3. An herbicide formulation comprising a composition as claimed in claim 1 and at least one solid or liquid carrier.

4. A method for controlling undesirable vegetation, comprising treating plants or their habitat with a composition as claimed in claim 1 .

5. A method for controlling undesired vegetation, comprising applying a synergistic herbicidal composition comprising: a) a herbicide A which is 3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole; and
b) a herbicide B which is selected from the group consisting of dicamba, its salts and its esters, before, during, and/or after the emergence of the undesirable plants; wherein the relative amount of herbicide A to herbicide B is 100:1 to 1:100.
