咖啡叶片褐眼斑病是由咖啡生尾孢(Cerc spora coffeicola Berk.et CK.)引起的,此病害具有经济重要性。苗圃幼苗或新植区的幼苗如直接暴露于阳光下,叶片就易感染此病。种植在良好荫蔽下的咖啡树则发病较轻。在苗圃通常于4—11月份发生此病,感病植株的叶片脱落,因而不宜移植大田。

Brown leaf spot on coffee leaves is caused by Cercospora coffeicola Berk. Et CK. This disease is economically important. Nursery seedlings or newly planted seedlings such as direct exposure to the sun, the leaves are vulnerable to the disease. Coffee trees planted under good shade are less affected. In the nursery, the disease usually occurs in April-November. The leaves of susceptible plants fall off, so it is not appropriate to transplant the fields.
