Arizona Mulberry Bark Peeling: Sooty Canker, Prune and Treat

Three mulberries (two 70-yr fruiting died with bark peeling; third male has peeling trunk). Deep flood irrigation.

Diagnosis: Sooty Canker

Fungal disease (Hendersonula toruloidea). Symptoms: wilted leaves, moist bark cracks, peeling. If bark loss circles trunk (girdling), that part dies.

Treatment

• Prune infected areas with clean tools; disinfect between cuts (bleach).
• Trim peeling bark, apply fungicide.
• Use Neem (organic) or stronger since male won't fruit.
• Seal with tree paint.
• Trash all infected wood.
• Avoid unnecessary pruning.

Should save third tree if not girdled.
