Identification,Biological Characteristics and Fungicides screening of Pathogens of Anthracnose of Tea Plants(Camellia sinensisl(L.)O.Ktze)in Zhejiang Province
摘要
Abstract
To clarify the pathogen species causing tea anthracnose in Zhejiang Province,typical symptomatic diseased leaves were collected from several counties in Hangzhou,Shaoxing,Lishui,Zhejiang Province.Based on single-spore isolation,pathogenicity determination and molecular biological identification,the pathogens were identified as Sinodiscula theae-sinensis.The effects of different carbon and nitrogen sources,temperatures,light,pH and culture conditions on the isolate(CY-D1)were investigated.The inhibitory effects of CY-D1 on pyraclostrobin,chlorothalonil and difenoconazole were determined.The results suggest that the most suitable culture media was potato dextrose agar media(PDA),with the optimal temperature and pH being 25℃and 7,respectively.The optimal carbon and nitrogen sources were found to be raffinose or beef powder and tryptone.Light had no effect on the mycelium of CY-D1.Pyraclostrobin,chlorothalonil and difenoconazole had inhibitory effect on the mycelium of CY-D1,with EC50 values of 0.1292、0.0368、0.0194 μg/mL,respectively.These findings provided a basis for further research into the interaction mechanism between the tea anthracnose pathogen and tea plants,as well as for the scientific management of this disease.关键词
