A Study on the Disease in Cerasus Pseudocerasus in Xi'an

近年来由于西安市农业产业结构的调整,樱桃在该市东郊栽培面积逐渐增加,同时病害的种类和危害程度亦随之增加,尤其是引起芽下发生肿瘤状的一种病害,目前对樱桃的生产已造成巨大的危害.该研究通过对该病害的调查,病原菌的常规分离、初步鉴定及药剂筛选,初步认为病害后期有大量根霉属真菌侵染.

In recent years, the cultivation area of Cerasus has been gradually increased in the eastern suburb of Xi＇ an with the readjustment of agricultural structure. Meanwhile, various kinds of diseases have also been on the increase. At the present, one of the most harmful diseases is the one that causes cancer under the bud. This study diagnoses the disease through isolating and identifying the pathogen and fungicide screening. The result shows that the pathogen of this disease belongs to Rhizopus Ehrenberg.
