Abstract
The invention relates to a herbicidal composition comprising a herbicidally acceptable carrier and/or surface active agent and, as active ingredient, a synergistically effective amount of (1) at least one compound of formula I 1 in which R1, R2, A, m and n are as defined in claim 1; and (2) at least one additional herbicidal compound, which is active against broad-leaved weeds and/or annual grasses; which provides a synergistic effect against a broad spectrum of weed species, e.g., in cereal crops. The invention also provides a method for controlling weeds by applying a synergistically effective amount of a compound (1) and a compound (2) to a locus.
Claims23

- (1) at least one 2-phenyl-4-(hetero-)aryloxypyrimidine of formula I
- 5
- wherein
- A represents an optionally substituted phenyl group or an optionally substituted 5- or 6-membered nitrogen-containing heteroaromatic group or a difluorobenzodioxolyl group;
- m represents an integer from 0 to 2;
- n represents an integer from 0 to 5;
- R1 (or each R1) independently represents a halogen atom, an optionally substituted alkyl, alkenyl, alkinyl, alkoxy, alkoxyalkyl, dialkoxyalkyl, alkoxyalkoxy, alkylthio, amino, alkylamino, dialkylamino, alkoxyamino or formamidino group;
- R2 (or each R2) independently represents a halogen atom, an optionally substituted alkyl, alkenyl, alkinyl, haloalkyl, haloalkoxy, alkoxy, alkoxyalkyl, alkoxyalkoxy, alkylthio, haloalkylthio group or a nitro, cyano, SF5 or a alkylsulphonyl or alkylsulfinyl group;
- or ist environmentally compatible salts;
- and
