关于这种疾病
Infestation by scale insects that attach to stems and leaves to feed on plant sap. Left unaddressed, they can trigger sooty mold and significantly weaken the plant.
主要症状
- Small white, cream, or brown shell-like bumps attach to stems and leaf bases
- A sooty black residue may appear on leaf surfaces
- Overall plant growth slows and new shoots fail to develop
- Leaves may yellow or shrivel in affected areas
主要原因
- Long-term management in poorly ventilated or dry indoor conditions
- Introduction of infested plants or new stock from outside
- Pests spreading between plants in overcrowded growing spaces
- Proliferation in indoor settings with few natural predators
预防（栽培环境与日常管理）
Quarantine newly purchased plants for a period to check for pests. Inspect plants regularly and maintain good air circulation. Avoid overcrowding by spacing plants adequately.
