Pests, Diseases & DisordersWhy can removing dead mango debris leave a scab reservoir behind?
The scab fungus survives on living plant tissue, unlike anthracnose organisms that can also produce spores on dead material. Inspect persistent lesions on leaves, petioles, and stems when planning sanitation for confirmed scab. Removing fallen debris remains useful housekeeping but does not remove every source. Have a specialist identify the affected living tissue before choosing pruning, since stripping healthy foliage indiscriminately can create another problem.
