Sixteen novel strobilurins containing 1,3,4-thiodiazole ring were synthesized by multi-step reactions including acylation, alcoholysis, hydrazinolysis, nucleophilic addition, dehydration and nucleophilic substitution from initial substituted benzoic acid and their structures were characterized by 1H NMR, IR, MS and HRMS. The results of bioassay indicated that the fungicidal activity of title compounds is better against Rhizoctonia solani Kühn and Fusarium oxysporum than Phytophthora infestans in vitro, while remarkably higher when against Colletetrichum orbiculare. Especially, compounds 5a5c, 5g, 6a6c displayed higer fungicidal activities than azoxystrobin, the inhibitory rate of 5g is 77.5% at the concentration of 100 μg/mL.
