摘要
柑桔炭疽病在正常气候条件和中上管理水平的果园,一般不发病。如遭受不良因素影响和矢尖蚧等病虫危害而导致树体局部器官组织衰弱或死亡时,都会规律性地引起发病显症。
Citrus trees rarely suffer from citrus anthracnose under normal weatherconditions and satisfactory orchard management.If the trees are weakenedor dead as a result of such adverse factors as citrus snow scale(Unapsiscitri)attack,diseases,freeze injury,drought,pesticide contaminationand poor orchard mangement,and part of their tissues is forced intoweak manner,the citrus anthracnose will regularly show the diseasesymptoms.
