Abstract:
Taking blueberry as the experimental materials,tissue isolation method was used to obtain the pathogenic fungi of blueberry branch blight,and morphological and molecular biological identifications were conducted.Based on different carbon and nitrogen sources,temperature,and pH,the biological characteristics of pathogenic fungi were studied.The effect of four kinds of commonly chemical fungicides on pathogenic fungi was determined by using the mycelial growth rate method.The classification status，biological characteristics，and sensitive fungicides of this pathogen were studied,in order to provide reference for the epidemic prediction and scientific prevention and control of branch blight，which seriously affects the economic value of blueberry branches，flowers and fruits wither and wither，and even plants die.The results showed that the pathogen causing blueberry branch blight was Neopetalotiopsis clavispora.The biological characteristics of the pathogen showed that the optimal carbon source was maltose,the optimal nitrogen source was ammonium dihydrogen phosphate，the optimal pH was 8，and the optimal temperature was 25 ℃.The results of inhibitory test showed that a compound fungicide of pentazole·prochloraz had the best inhibitory effect on N.clavispora.
