Abstract A series of substituted derivatives of triazolyl acetanilides (IIa-IIn) by reaction of 1- chloroacetanilides with 1, 2, 4-triazole was prepared. The basic IR and 1 H NMR spectral data of final products are presented. Investigation of herbicidal, fungicidal and growth- regulation activity showed, that none of the studied compounds was more efficient that currently used compounds.
