Abstract Three novel vanillin benzimidazole Schiff bases(5a~5c) were synthesized, using o-phenylenediamine and vanillin as raw materials. The structures were characterized by 1H NMR and IR. The antibacterial activities of 5a~5c against Fusarium oxysporium(F.oxy), Alternaria solani(A.sol), Fusarium graminearum(F.gra), Cercospora sorghi(C.sor) and Fusaurium oxysporiumf. sp. vasinfectum(F.oxy) were investigated by mycelial growth rate method. The results indicated that 5c exhibited better antimicrobial activities against F.gra, F.ox and C.sor than Carbendazim with EC50 of 19.76 mg·L-1， 24.94 mg·L-1 and 29.15 mg·L-1.
