桑椹菌核病的发生与防治技术研究进展

Research Progresson Comprehensive Prevention and Control Techniques of Mulberry Fruit Sclerotiniosis

文章介绍了桑椹菌核病的病原菌和发病症状,从发生条件、侵染过程及流行规律等方面阐述了桑椹菌核病的发生规律,从品种抗病性、菌源积累、气候条件和栽培管理等方面分析了桑椹菌核病的发生原因,从选用抗病品种、加强田间管理和清除菌源等方面介绍了桑椹菌核病的农业防治措施,从生防菌筛选和绿色防控药剂的筛选等方面介绍了主要生物防治技术,介绍了不同化学农药对桑椹菌核病的防治效果及其农药残留情况。笔者认为对桑椹菌核病的防治,应在选用抗病品种、科学栽培、及时清除菌源等农业防治措施的基础上,采取生物防治为主、药剂防治为辅的综合防治模式,既能较好地控制病害的发展,又能满足人们对绿色食品的需求。

In this paper,the pathogen and symptoms of mulberry fruit sclerotiniosis were introduced,and the epidemic regularity of mulberry fruit sclerotiniosis was expounded from the aspects of occurrence condition,infection process and epidemic regularity.The causes of mulberry fruit sclerotiniosis were analyzed from the aspects of disease resistance,fungus source accumulation,climate conditions and cultivation management.The agricultural control measures of mulberry fruit sclerotiniosis were introduced from the aspects of selection of resistant varieties,field management and elimination of mycelium origin.The control effects of different chemical pesticides on mulberry fruit sclerotiniosis and their residues were introduced.The control of mulberry fruit sclerotiniosis should be based on the agricultural control measures such as selecting disease-resistant varieties,scientific cultivation and removing the source of fungi in time,the integrated control model with biological control as main and chemical control as auxiliary can not only control the development of the disease,but also meet the needs of people for green food.
