Abstract

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

First claim

The invention claimed is:

1. A herbicide-safener composition comprising
(A) one or more compounds of formula (I) or a salt thereof,

in which the symbols and indices are defined as follows:
A is N or CY,
R is methyl or (CH 2 ) 2 OMe;
X is Cl or methyl;
Y is OCH 2 CF 3 , OCH 2 CH 2 F, SO 2 Me, SO 2 Et, O-nPr, or SOCH 2 c-Pr
Z is SO 2 Me or CF 3 ;
and
(B) one or more safeners selected from S1-1: mefenpyr-diethyl, S1-7: fenchlorazol-ethyl, S1-11: isoxadifen-ethyl, S2-1: cloquintocet-mexyl, S3-4: benoxacor, S3-10: furilazole, S4-1: cyprosulfamide, S4-6:1-[4-(N-2-methoxybenzoylsulfamoyl)phenyl]-3-methylurea, or S11-2: oxabetrinil,
wherein the weight ratio of the compound of formula (I) (A) to safener (B) is in the range from 0.9:1 to 1:20.

2. The herbicide-safener composition as claimed in claim 1 , in which
A is CY,
R is methyl
X is chlorine.

3. The herbicide-safener composition as claimed in claim 1 , in which
A is N or CY,
R is Me.

4. The herbicide-safener composition as claimed in claim 1 , comprising at least one safener which is mefenpyr-diethyl.

5. The herbicide-safener composition as claimed in claim 1 , comprising at least one safener which is cyprosulfamide.

6. The herbicide-safener composition as claimed in claim 1 , comprising at least one safener which is cloquintocet-mexyl.

7. A method for controlling harmful plants in crops of useful plants, comprising applying a herbicidally active amount of a composition as claimed in claim 1 to one or more harmful plants, plants, plant seeds and/or an area on which plants grow.

8. The method as claimed in claim 7 , wherein the useful plants are selected from the group consisting of sugar cane, corn, wheat, rye, barley, oats, rice, sorghum, cotton and soya.

9. The method as claimed in claim 7 wherein the useful plants have been genetically modified.

10. The herbicide-safener composition as claimed in claim 1 , in which
A is CY,
R is Me,
X is Me,
Y is SO 2 Me, and
Z is CF 3 .

11. The herbicide-safener composition as claimed in claim 1 , wherein the safener is isoxadifen-ethyl.

12. The herbicide-safener composition as claimed in claim 1 , in which
A is CY,
R is Me,
X is Me,
Y is SO 2 Me,
Z is CF 3 ,
and the safener is isoxadifen-ethyl.

13. The herbicide-safener composition as claimed in claim 1 wherein the weight ratio of the compound of formula (I) (A) to safener (B) is in the range from 1:10 to 0.9:1.

14. The herbicide-safener composition as claimed in claim 6 wherein the weight ratio of the compound of formula (I) (A) to safener (B) is in the range from 1:10 to 0.9:1.

15. The herbicide-safener composition as claimed in claim 12 wherein the weight ratio of the compound of formula (I) (A) to safener (B) is in the range from 1:10 to 0.9:1.
