Abstract:: By means of the mycelium growth rate methods，the suppressive effect of seven fungicides on evergreen anthrax pathogens was tested.And at the same time，field experiments were conducted to verify the results of the experiment.The results showed that when using 25% prochloraz,45%prochloraz,hexaconazole,Pyrazole kresoxim-methyl，the inhibition rate to germs was 100 percents.The suppressive effect of difenoconazole follows closely.Though the inhibition ratio of thiophanate-methyl was better than azoxystrobin，Thiophanate-methyl not suppress the production of conidium.The field experiment results further proof that the suppressive effect of 25% prochloraz，45%prochloraz， Hexaconazole，Pyrazole kresoxim-methyl on evergreen anthrax was better and can be used interchangeably.The suppressive effect of difenoconazole follows closely.The suppressive effect of thiophanate-methyl and azoxystrobin was bad and did not have any significant variation.
