Using seedvax as leading compound, seventeen new seedvax analogues N-substituted-4-methyl-5-aminothia-zole-2-benzamides were designed and synthesized. The structures of the target compounds were characterized by 1H NMR, 13C NMR, HRMS and IR spectral analyses. The preliminary bioassay results of fungicidal activities (FA) in vitro showed that most of the target compounds displayed higher activities than seedvax. Among them, the FA against Alternaria solani of one compound is 2.6 times of seedvax, the FA of 6 compounds against cucumber Fusarium wilt are more than 2 times of that of seedvax; the FA of 16 compounds against Colletotrichun orbiculare and Fusarium fujikuroi were higher than that of positive control. Especially, the FA against Colletotrichun orbiculare of seven compounds are more than twice of seedvax.
