Mealybugs

These small, soft-bodied insects secrete a white, waxy, cotton-like substance to protect themselves as they feed on the sap of the Spathiphyllum. They often cluster at the leaf axils or where the petiole meets the stem.

Very Common

warning

Pseudomonas (Bacterial Soft Rot)

Certain bacterial pathogens can cause white, water-soaked lesions on the leaves that may appear fuzzy or moldy as secondary fungi colonize the decaying tissue. In 'Bingo Cupido', this often presents as translucent spots that eventually turn dark.

Common

warning

Sclerotinia (White Mold)

High humidity levels in Peace Lilies can trigger fungal growth that appears as white, cottony mycelium on the surface of the leaves or stems. This fungus thrives in the damp microclimates often found around Spathiphyllum foliage.

Common
