Abstract:: The antibacterial effects of 12 reagents on Chrysanthemum coronarium anthracnose were studied in this paper.The results showed that tebuconzole was better than others treatment significantly in the antibacterial effect and persistence.Secondly were hexaconazole，chlorothalonil and mancozeb，and the next were iprodione，hymexazol and propamocarb hydrochloride.The persistence of hymexazol and propamocarb hydrochloride was the worst.Inhibition zone of other reagents had not significant difference with control.The rusults of colony growth rate showed that no colony was found with treatments by tebuconzole，hexaconazole，chlorothalonil and mancozeb，which antibacterial and germicidal efficacy was good.On edge of colony，mycelium was dwarf，sparse and grew bad when it was treated by iprodione and hymexazol，which suggested the two reagents had some antibacterial effects.Germicidal efficacy of other regents was not obvious.
