Mealybugs

These small, soft-bodied insects secrete a white, waxy, cotton-like substance to protect themselves while feeding on the lily's sap. They often congregate at the leaf axils or beneath the flower buds of Lilium cultivars.

Very Common

Powdery Mildew

This fungal disease manifests as white, flour-like patches on the surface of the leaves. High humidity and poor air circulation around the dense foliage of Red Latin Lilies create the perfect environment for spore germination.
