摘　　要：猕猴桃“黑头病”是近年来陕西周至县‘翠香’猕猴桃品种上新发生的真菌性病害,一般每年7月中下旬至8月初发病,8月底至9月初达到病情高峰期。病害发生与环境温湿度、猕猴桃品种及田间管理水平密切相关。防治重点在加强田间管理,通过采取增施有机肥、保证果园通风透光条件等措施来提高树体自身抗病能力。同时采取合理施用药剂和免疫调节剂进行病害的早期预防,以防为主,提高病害防治效果。Black Spot on Kiwifruit is a new fungal disease of‘Cuixiang’kiwifruit cultivar in Zhouzhi County,Shaanxi Province in recent years.The disease usually occurs from mid-late July to early August each year.The peak of incidence is in late August to the early September.Disease occurrence is closely related to ambient temperature and humidity,kiwifruit varieties and field management level.The focus of prevention and control is to strengthen field management,and improve the disease resistance of the tree itself by taking measures such as increasing the application of organic fertilizers,ensuring the orchard ventilation and light transmission conditions.At the same time,reasonable application of drugs and immunomodulators should be taken for early prevention of diseases,so as to improve the effect of disease control.
