Powdery Mildew

This fungal pathogen thrives in high humidity and poor air circulation, common in indoor Spathiphyllum environments. It manifests as white, flour-like patches on the surface of the leaves, eventually leading to leaf yellowing or necrosis.

Very Common

Mealybugs

These small, soft-bodied insects secrete a white, waxy, cottony substance that can resemble powder or dust. They cluster in the leaf axils and under the foliage of Peace Lilies to suck sap.

How to confirm: Use a magnifying glass to check if the 'powder' is actually tiny moving insects hiding in leaf joints.

Mineral/Salt Deposits

Hard water or excessive fertilizer buildup can leave white, crusty residues on the leaf surfaces as water evaporates. This is particularly common in 'Bingo Cupido' if it is frequently misted with tap water.

Common

How to confirm: Wipe a leaf with a damp cloth; if the white substance disappears easily without leaving a sticky residue, it is likely mineral buildup.

1 Gently wipe the leaves with a soft, damp cloth using distilled or filtered water to remove the mineral crust without damaging the foliage.

2 Flush the soil thoroughly with distilled water to leach out accumulated mineral salts and prevent further buildup.

3 Switch to using rainwater or distilled water for misting and regular watering to avoid introducing new hard water deposits.
