Powdery Mildew

This is the most common cause of white, flour-like spots on Chrysanthemum foliage. The fungal pathogen (Erysiphe kusnezoffii) thrives in high humidity and moderate temperatures, colonizing the surface of leaves and stems.

Very Common

Mealybug Infestation

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They cluster in the leaf axils and under leaves of Aurelio Chrysanthemums, sucking plant sap.

Common

How to confirm: Inspect the undersides of leaves and stem nodes for tiny, slow-moving white insects.

2 Manually remove visible white cottony clusters using a cotton swab dipped in isopropyl alcohol to dissolve the protective waxy coating.
3 Isolate the affected Chrysanthemum from other plants to prevent the mealybugs from spreading to your healthy greenery.
warning

Scale Insects (White Scale)

Certain species of scale insects produce a white, powdery or waxy coating over their bodies as they mature. This can cause the chrysanthemum leaves to become sticky due to honeydew secretion.

Common

How to confirm: Check for small, stationary bumps on the stems that feel hard or crusty under the white residue.

Mineral Deposits (Hard Water)

If you are misting or overhead watering your Chrysanthemum, calcium and magnesium carbonates from hard water can leave white, crusty residues on the leaf surfaces.

Common

How to confirm: Check if the white spots are located primarily on the leaf edges or where water droplets dried.

1 Stop overhead watering or misting the foliage to prevent further mineral buildup on the leaves.
2 Gently wipe the leaves with a soft, damp cloth using distilled or filtered water to remove existing crusty deposits.
3 Use a water meter to monitor soil moisture and ensure you are only watering the soil directly, avoiding contact with the plant's leaves.
