A Schiff base was synthesized by 3-methyl-4-amino-5-ethoxycarbonyl-methylsul- fanyl-1,2,4-triazole with 3-nitrobenzaldehyde. The structure was confirmed by IH NMR, IR, H RMS, TGA techniques and X-ray diffraction. The crystal belongs to monoclinic system, space group P21/c, with a = 8.965（2）, b = 21.903（5）, c = 9.197（2） ,A, β = 114.011（4）°, CIaH15NsOnS, Mr = 349.08, V= 1649.7（6） A3, De = 1.407 g·cm-3, Z = 4, F（000） = 728,μ =0.226 mm1, the final R = 0.0574 and wR = 0.1336 for 2932 unique reflections with 1 〉 2σ（I）. Furthermore, the biological activity to four vegetable pathogens has been tested. The title compound exhibits better biological activity to four vegetable pathogens compared to the Schiff base without 5-ethoxycarbonyl and to Gibberlla saubinetti in EC95 compared with triadimefon.

A novel Schiff base was synthesized via 5-benzyl-4-amino-1,2,4-triazole-3-thione with 3-phenoxy-benzaldehyde under refluxing. The structure was characterized by elemental analysis, IR, 1H NMR, ESI-MS and single-crystal X-ray diffraction. This compound crystallizes in monoclinic, space group P21 /c with a = 16.0289（16）, b = 5.8022（6）, c = 20.542（2）, β = 95.667（2）o, C22 H18 N4 OS, Mr = 386.46, V = 1901.1（3）3, Z = 4, Dc = 1.347 g/cm3, F（000） = 804, μ = 0.191 mm-1, the final R = 0.0453 and wR = 0.1307 for 2456 observed reflections with I 〉 2σ（I）. The crystal packing of the compound is stabilized by classical intermolecular N–H…S hydrogen bonds. Furthermore, the biological activity to four vegetable pathogens has been tested. The title compound exhibited good fungicidal activities to Gibberlla nicotiancola.
