Abstract

The present invention relates to compounds of Formula (I), or an agronomically acceptable salt of said compounds wherein A 1 , A 2 , A 3 , Q, X, R 1 and R 2 are as defined herein. The invention further relates to herbicidal compositions which comprise a compound of Formula (I) and to the use of compounds of Formula (I) for controlling weeds, in particular in crops of useful plants.

First claim

1 . A compound of Formula (I):

or an agronomically acceptable salt thereof,
wherein
A 1 , A 2 and A 3 are independently CH or N with the proviso that not more than one of A 1 , A 2 and A 3 are N;
X is selected from the group consisting of O, S and CH 2 ;
Q is a 6-membered nitrogen containing heteroaryl which is optionally substituted by one or more R 3 ;
R 1 is selected from the group consisting of C 1 -C 4 alkyl, C 1 -C 4 haloalkyl and C 1 -C 4 alkoxy;
R 2 is selected from the group consisting of C 1 -C 4 alkyl, C 1 -C 4 haloalkyl, C 1 -C 4 haloalkoxy, halogen, C 1 -C 4 alkoxy, —S—C 1 -C 4 alkyl and —S—C 1 -C 4 haloalkyl;
R 3 is selected from the group consisting of halogen, C 1 -C 4 alkyl, C 1 -C 4 haloalkyl, C 1 -C 4 alkoxy, C 1 -C 4 haloalkoxy, —CN, NO 2 , C 2 -C 4 alkenyl, C 2 -C 4 alkynyl, —S(O) p C 1 -C 4 alkyl; and
p=0, 1 or 2.

2 . A compound of Formula (I) according to claim 1 , wherein X is O.

3 . A compound of Formula (I) according to claim 1 , wherein A 1 , A 2 and A 3 are all CH.

4 . A compound of Formula (I) according to claim 1 , wherein Q is selected from the group consisting of

wherein n is 0, 1 or 2.

5 . A compound of Formula (I) according to claim 4 , wherein Q is Q5.

6 . A compound according to claim 5 , wherein n is 1 or 2.

7 . A compound according to claim 6 , wherein n is 1 and R 3 is halogen.

8 . A compound according to claim 1 , wherein R 1 is C 1 -C 4 haloalkyl.

9 . A compound according to claim 1 , wherein R 1 is CF 3 .

10 . A compound according to claim 1 , wherein R 2 is selected from the group consisting of halogen, C 1 -C 4 haloalkyl and C 1 -C 4 haloalkoxy.

11 . A herbicidal composition comprising a compound according to claim 1 and an agriculturally acceptable formulation adjuvant.

12 . A herbicidal composition according to claim 11 , further comprising at least one additional pesticide.

13 . A herbicidal composition according to claim 12 , wherein the additional pesticide is a herbicide or herbicide safener.

14 . A method of controlling weeds at a locus comprising application to the locus of a weed controlling amount of a composition according to claim 11 .

15 . Use of a compound of Formula (I) as defined in claim 1 as a herbicide.
