Mealybugs

These small, soft-bodied insects secrete a white, waxy, cottony substance to protect themselves. On Conophytum burgeri, they often cluster around the crevices where the leaf pairs meet or at the base of the plant body.

Very Common

Botrytis cinerea (Gray Mold)

In high humidity environments, this fungus can manifest as fuzzy, white patches on the succulent tissue. For Conophytum burgeri, this is often a precursor to rapid tissue decay and rot.

Powdery Mildew

While less common on succulents than on leafy plants, certain fungal pathogens can create a white, flour-like coating on the surface of Conophytum leaves during periods of poor airflow.

Common
