FIELD: chemistry.

SUBSTANCE: invention relates to 5-phenyl-substituted N-(tetrazol-5-yl)- and N-(triazol-5-yl)-amides of arylcarboxylic acids of formula (I) or their salts: . In formula (I), A is N or CY, B is N or CH, X is halogen, (C₁-C₆)-alkyl, OR¹ or NR¹COR¹, Y is hydrogen, halogen, (C₁-C₆)-alkyl, COOR¹, OR¹, S(O)_nR², N(R¹)_2, (C₃-C₆)-cycloalkyl-(C₁-C₆)-alkoxy, azetidin-2-one-1-yl or pyrazol-1-yl, Z is halogen, cyano, halo- (C₁-C₆)-alkyl, S(O)_nR², (C₁-C₆)-alkyl-OR¹ or Z can also be hydrogen if Y is the residue of S(O)_nR², W is (C₁-C₆)-alkyl, (C₁-C₆)-alkoxy or halogen, R is (C₁-C₈)-alkyl which is substituted by s-number of residues selected from the group consisting of (C₁-C₆)-alkoxy, R¹ is hydrogen, (C₁-C₆)-alkyl or halo-(C₁-C₆)-alkyl, R² is (C₁-C₆)-alkyl, n is 0, 1 or 2, and s is 0 or 1. The invention also relates to a herbicide, a method of controlling undesirable plants and the use of compounds for controlling undesired plants.

EFFECT: new compounds have been obtained that can be used as herbicides.
