Troubleshooting
Yellow Mombin problems — and how to fix them
Yellow Mombin (Spondias mombin) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Fruit fly infestation (Anastrepha spp.)
Tropical fruit flies are the primary pest, laying eggs in ripening fruit causing premature drop and internal rot. Use protein bait traps, fruit bagging, or spinosad-based treatments. Harvest fruit promptly as it ripens.
Anthracnose (Colletotrichum spp.)
Causes dark sunken lesions on fruit and blossom blight in humid conditions. Improve air circulation with pruning and apply copper-based fungicides at flowering. Avoid overhead irrigation during flowering.
Bark borers
Longhorn beetle larvae can bore into trunk wood, especially on stressed trees. Maintain tree vigour with adequate moisture and nutrition. Remove and destroy infested branches; apply kaolin clay or appropriate insecticide to wounds.
