Mealybugs

These small, soft-bodied insects produce a white, waxy, cottony secretion to protect themselves. They feed on the sap of the Pachypodium succulentum, often clustering in the leaf axils or crevices of the succulent stem.

Very Common

How to confirm: Use a cotton swab dipped in rubbing alcohol to wipe the spots; if they dissolve and reveal tiny insects underneath, it is mealybug infestation.

Sclerotinia (White Mold)

In conditions of high humidity and poor airflow, certain fungal pathogens can produce white, mycelium-like growth on the surface of the plant. This is less common in succulents but can occur if the base of the Pachypodium is too damp.

Common
