Whiteflies (Infestation)

Adult whiteflies congregate on the undersides of leaves, excreting honeydew that can develop a white, sooty mold or appear as tiny white moving specks. This stress leads to leaf chlorosis and stunted fruit development in pepper plants.

Common

How to confirm: Tap the underside of a leaf gently to see if small white insects fly upward into the air.

Mealybugs

Common

Mineral/Salt Deposits

Excessive buildup of calcium or other minerals from hard water or over-fertilization can leave white, crusty residues on the leaf surface. This is not a biological pathogen but an abiotic stressor caused by evaporation.

Common

lightbulb

How to confirm: Check if the white residue is only present on the edges of leaves or where water droplets have dried.

1 Gently wipe the leaves with a soft, damp cloth to remove the mineral crust and prevent further leaf damage.

2 Flush the soil thoroughly with distilled water or rainwater to leach out accumulated mineral salts from the root zone.

3 Switch to using a high-quality liquid supplement to balance nutrients and avoid further salt buildup.
