關於這種疾病
Pest damage caused by insects with hard shell-like coverings that attach to leaves and stems and feed on plant sap, potentially weakening the agave. Heavy infestations can affect overall plant vigor.

- Feeding sites may turn yellow or become sunken
- Overall plant growth slows or declines
- Sooty mold (black sooty deposits) may develop concurrently
主要原因
- Growing in dry conditions that favor scale insects
- Management in poorly ventilated enclosed spaces
- Introduction via other plants or newly purchased specimens
- Ants facilitating the spread of scale insects
預防（栽培環境與日常管理）
Inspect the undersides of leaves and stems of newly purchased plants before introducing them to other plants. Maintain good airflow and inspect regularly for early detection.
