全球松树枯梢病发生状况与防治策略

松树枯梢病是一种世界性病害。该病寄主范围广，可侵染8个属约60种（含变种）针叶树。对全球松树枯梢病为害较严重国家（新西兰、南非、美国和中国等）的发生状况以及近年有关该病发生发展的流行诱因和抗性研究等进行了概述，并提出以树种生态适应性、提高寄主生长势为主以及控制病菌增量的防治策略。

Occurence and Control Countermeasure of Sphaeropsis sapinea Shoot Blight on Conifer in the World

Sphaeropsis sapinea causes shoot blight,canker,collar rot and blue stain of 8 genera conifer (hosts up to ca. 60 species and varieties).The disease occurs worldwide and has been reported from at least 30 countries. It has been associated with significant economic damage in exotic pine plantations in New Zealand, South Africa and China. Environmental conditions (Climate, site, nutrient availability) and host susceptibility have great effect on incidence of darnage caused by the parasitlc fungus. The practical disease controt measures are to enhance host growth by the selection of suitable site, the replacement of susceptible species and cultivars with more resistant species and cultivars and the reduction of physiological stress of hosts. Attention has been given to chemical and biological control of S. sapinea in nurseries and plantations.
