Abstract:
Taking Salvia miltiorrhiza Bge.collected from Ji county，Tianjin，as the test material，pathogens were isolated from typical disease samples via tissue separation.Subsequently，pathogenicity was confirmed through detached leaf inoculation tests following Koch′s postulates，and the pathogens were re-isolated and identified.The species and biological characteristics of the pathogen causing anthracnose in Tianjin were investigated，aiming to clarify its optimal growth conditions for future prevention and control of Colletotrichum fioriniae in Salvia miltiorrhiza Bge.，as well as to provide a reference for developing strategies against anthracnose and further exploring its pathogenic mechanisms.The results showed that the pathogen causing anthracnose was Colletotrichum fioriniae，which grew differently under different conditions，could adapt to various growth environments，and had strong vitality，and the most suitable growth conditions were full light，temperature 20-30 ℃，pH 8-9，the most suitable carbon source was sucrose,and the most suitable nitrogen was beef paste,the trace element was magnesium sulfate，and the medium was CPDA.
