Abstract:: Taking commercially available 12 pesticides as materials,inhibition zone and bacterial colony rate were determined,antibacterial effect to Fusarium wilt were measured.The results showed that the iprodione was best in the antibacterial effect and persistence.Next were tebuconazole alcohol，chlorothalonil，hexaconazole.Persistence of chlorothalonil and hexaconazole were poor.The rest of the pharmaceutical treatment had no significant effect.The results of colony growth rate showed that antibacterial bactericidal effect of iprodione was good，which mycelium was dry，formed no spore，and nearly died under treatment of iprodione.Tebuconazole alcohol，chlorothalonil，hexaconazole and mancozeb were secondary，with short stature at the edge of the mycelium and poor growth，which showed there was some inhibitory bactericidal effect.Inhibitory bactericidal effects of other pharmaceutical treatment were not significant.
