Twenty-one new derivatives have been synthesized using 3-substituted-4-amino-5-mercapto-1,2,4-triazale and pyrazole carboxylic acid as the staring materials. The structures of the title compounds were characterized by IR, 1H NMR and elemental analyses. The wheat gemma method preliminary bioassay results indicated that some compounds display herbicidal activity to some extent, and bacteriostatic activity test results show that the part of compounds show excellent fungicidal activity, particularly compounds 3g and 3h exhibit higher than the others, and were similar with chloramphenicol. The minimum inhibitory concentrations (MIC) of 3g and 3h with Escherichia coli and Staphylococcus aureus is 6.25 and 3.13 mg/L, and 12.5 and 6.25 mg/L, respectively.
