Mealybug Infestation

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They congregate in the leaf axils and tight crevices of the Tango Lily bulbs and stems, sucking sap and weakening the plant.

Very Common

Cottony Blotch (Botrytis cinerea)

While often presenting as brown spots, advanced stages of Botrytis can develop a greyish-white, fuzzy mold appearance on decaying lily tissue. This is common in Lilium species when moisture lingers on the petals or leaves.
