苹果炭疽叶枯病防治技术研究

Study on the Control Techniques of Apple Glomerella Leaf Spot

苹果是我国栽培面积大、产量高的大宗水果。炭疽叶枯病是苹果生产中的常见病害,潜育期短,产孢量大,发病急,流行速度快,来势猛,对苹果产业威胁巨大。本文简述了国内苹果炭疽叶枯病的病症病状,从抗病品种选育、生物源农药筛选及绿色防控、拮抗菌株筛选及防控、减药增效集成防控等方面对防控技术进行了综述,以拓展防控思路,实现对苹果炭疽叶枯病的科学绿色防控。

Apple is a bulk fruit in China,with large cultivation area and high yield.Apple glomerella leaf spot is a common disease in apple production.It has a short incubation period,a large amount of sporulation,a rapid epidemic rate and a great threat to apple industry.In this paper,the symptoms of apple glomerella leaf spot in China were summarized,the control techniques were summarized from the aspects of resistant variety breeding,biological pesticide screening and green control,antagonistic strain screening,and integrated control of reducing pesticide and enhancing effect,to achieve scientific green prevention and control.
