藏品描述：病原菌可侵害蘆筍莖、枝及葉，於其上形成病斑，初發生時沿著莖生出紡錘形或線狀暗褐色病斑，周緣呈水浸狀，病斑逐漸擴大，中央部份呈赤褐色凹陷，上面散生許多黑色柄子殼；病斑圍繞莖枝，使得病斑上部乾枯而死，呈火燒狀；雨水、濃霧、露水及枝葉繁茂所造成高濕度均使成熟的柄孢子由柄子殼中釋放而傳播、發芽侵入健全組織。

The causal fungus is known Phomopsis asparagi. Elongated, oval‐shaped, lesions were formed on the stems, starting as light brown lesions that later turned dark reddish brown. The central tissue was pale in color, and pycnidia appeared on old lesions. The disease was found on leaves and any part of the stem. More lesions occurred on the stem base than on the upper parts of the plant. Cladodes became yellow and later brown until complete desiccation and stem death occurred as a consequence of the disease.
