Powdery Mildew

This fungal disease is common in Capsicum species when humidity is high and airflow is restricted. It manifests as white, flour-like patches on the surface of leaves and can eventually cause defoliation.

Very Common

Whiteflies

Infestations of whiteflies result in tiny, winged insects congregating on the undersides of leaves. While they don't look like powder themselves, their presence and the honeydew they secrete can lead to secondary fungal growth (sooty mold) or a dusty appearance.

Common
