Powdery Mildew

Very Common

Mealybugs

These small, soft-bodied insects secrete a white, waxy, cottony substance to protect themselves. In Tango Yellow peppers, they often cluster around nodes and new growth, sucking sap and weakening the plant.

Common

Common

Calcium Deficiency (Salt Deposits)

In some cases, heavy mineral buildup from hard water or over-fertilization can appear as white crusty spots on the plant surface. While not a fungus, it mimics 'white powder' and can cause blossom end rot in Capsicum species.

Common

How to confirm: Check if the white spots are crusty/hard and located specifically on the leaf edges or fruit surfaces.
