Abstract:
Taking disease Paeonialud lowii as test material,pathogen was identified by conventional cultivation，morphological identification，pathogenicity test,then effective medicament was screened by agar mycelial growth inhibition method.The results showed that the pathogen were fungi belonging to Deuteromycotina of Phyllosticta commonsii on leaf spot pathogen of Paeonia ludlowii.The 30% thiram wettable powder and 80% Pyrimethanil WDG (500 times diluent liquid) had better effect to constrain its hypha growth in laboratory，the inhibitory rate were 82% and 84%，respectively.The results of this study provided a foundation for the effective control of the disease.
