Abstract

What are described are herbicidal compositions comprising active ingredients from the group of the N-(1,3,4-oxadiazol-2-yl)arylcarboxamides and further herbicides and optionally safeners. These herbicidal compositions are particularly suitable for use against harmful plants in crops of useful plants.

First claim

The invention claimed is:

1. A herbicidal composition comprising
(A) one or more compounds of formula (I) or salts thereof as component A

in which
A is CY,
R is (C 1 -C 4 )-alkyl, cyclopropyl, methoxymethyl, or methoxyethyl,
X is halogen or (C 1 -C 6 )-alkyl,
Y is OR 1 or S(O) n R 2 ,
Z is halo-(C 1 -C 6 )-alkyl or S(O) n R 2 ,
R 1 is (C 1 -C 6 )-alkyl or (C 1 -C 6 )-haloalkyl,
R 2 is (C 1 -C 6 )-alkyl, and
n is 1 or 2,

and
(B) synergistically effective amounts of one or more herbicides selected from the group consisting of B1, B2, B4, B5, B8, and B11 as component B:
B1 1,3-diketo compounds selected from the group consisting of tembotrione and pinoxaden at a weight ratio of component A to the 1,3-diketo compound of from 1:4 to 8:1,
B2 (sulfon)amides selected from the group consisting of foramsulfuron, iodo-sulfuron-methyl-sodium, mesosulfuron-methyl, and thiencarbazone-methyl at a weight ratio of component A to the (sulfon)amide of from 1:10 to 400:1,
B4 azoles selected from the group consisting of pyrasulfotole, and isoxaflutole at a weight ratio of component A to the azole of from 1:40 to 1:1.25,
B5 an herbicide that is flurtamone at a weight ratio of component A to flurtamone of from 1:128 to 1:8,
B8 phenyl ethers selected from the group consisting of aclonifen and fenoxaprop-P-ethyl at a weight ratio of component A to the phenyl ether of from 1:64 to 1:2.5, and
B11 a triazine selected from the group consisting of indaziflam and metribuzin at a weight ratio of component A to the triazine of from 1:200 to 1:4.

2. The herbicidal composition as claimed in claim 1 comprising
(A) one or more compounds of formula (I) or salts thereof as component A in which
(1) A is CY, R is methoxymethyl, X is methyl, Y is SO 2 CH 3 , and Z is trifluoro-methyl,
(2) A is CY, R is methyl, X is chlorine, Y is SO 2 CH 2 CH 3 , and Z is trifluoromethyl,
(3) A is CY, R is methyl, X is methyl, Y is SO 2 CH 3 , Z is trifluoromethyl,
(4) A is CY, R is methyl, X is chlorine, Y is SOCH 3 , and Z is trifluoromethyl,
(5) A is CY, R is cyclopropyl, X is methyl, Y is SOCH 3 , Z is trifluoromethyl,
(6) A is CY, R is methyl, X is chlorine, Y is SO 2 CH 3 , and Z is trifluoromethyl, or
(7) A is CY, R is methyl, X is chlorine, Y is OCH 2 CH 2 F, and Z is SO 2 CH 3 ,

and
(B) synergistically effective amounts of one or more herbicides selected from the group consisting of B1, B2, B4, B5, B8, and B11 as component B:
B1 1,3-diketo compounds selected from the group consisting of tembotrione and pinoxaden at a weight ratio of component A to the 1,3-diketo compound of from 1:4 to 8:1,
B2 (sulfon)amides selected from the group consisting of foramsulfuron, iodo-sulfuron-methyl-sodium, mesosulfuron-methyl, and thiencarbazone-methyl at a weight ratio of component A to the (sulfon)amide of from 1:10 to 400:1,
B4 azoles selected from the group consisting of pyrasulfotole, and isoxaflutole at a weight ratio of component A to the azole of from 1:40 to 1:1.25,
B5 an herbicide that is flurtamone at a weight ratio of component A to flurtamone of from 1:128 to 1:8,

B8 phenyl ethers selected from the group consisting of aclonifen and fenoxaprop-P-ethyl at a weight ratio of component A to the phenyl ether of from 1:64 to 1:2.5, and
B11 a triazine selected from the group consisting of indaziflam and metribuzin at a weight ratio of component A to the triazine of from 1:200 to 1:4.

3. The herbicidal composition as claimed in claim 1 additionally comprising, as component C, one or more safeners selected from the group consisting of benoxacor, cloquintocet-mexyl, cyprosulfamide, dichlormid, fenclorim, fenchlorazole, furilazole, isoxadifen-ethyl, mefenpyr-diethyl, 4-(dichloroacetyl)-1-oxa-4-azaspiro [4.5] decane, and 2,2,5-trimethyl-3-(dichloroacetyl)-1,3-oxazolidine.

4. A method of controlling harmful plants in crops, comprising applying a herbicidally active amount of a herbicidal composition as claimed in claim 1 to the harmful plants, plants, plant seeds or an area on which plants grow.

5. The method as claimed in claim 4 , wherein the plants are selected from the group consisting of sugar cane, corn, wheat, rye, barley, oats, rice, sorghum, cotton and soya.

6. The method as claimed in claim 4 , wherein the plants have been genetically modified.
