Diseases That Cause White Powder on Leaves

Diseases that cover the leaves with fluff or white powder affect many types of plants. If you carefully examine the white leaves and do not notice any insects, most likely the cause is a disease. Two common diseases cause a white powdery mildew coating on plants and garden crops:

Powdery mildew causes white powder on the leaves of roses.

Powdery mildew is a fungal disease that covers leaves and stems in white powder. Unlike many fungal diseases, powdery mildew attacks most violently in warm, dry, shady conditions and high humidity.

Different types of powdery mildew affect different plant families, but the white powder on the leaves of roses and tomatoes often comes from this source. Pumpkin zucchini and cucumber leaves also fight against powdery mildew. White powder usually begins on the upper side of the leaves of the plant.

Downy mildew coats the underside of the leaves.

Downy mildew is more closely related to algae than fungi, but it looks and acts very similarly to fungal diseases. In contrast to powdery mildew, downy mildew thrives in cold and humid weather when the leaves remain wet for a long time.

Crowded conditions helped the spread. Vegetables such as broccoli, cabbage and cauliflower are often targeted. Pumpkins and cucumbers also suffer from this fungus. Grayish-white fluff usually appears on the underside of the leaves, while yellow spots adorn the upper side of the leaves.

Insects That Cause White Spots on Plants

At first glance, all the white things on the leaves of your plant look like diseases. But a closer look might reveal a move you didn’t expect. Some types of insect pests leave white powdery grains on the leaves of plants. Three common causes in ornamental and garden crops:


Got its name from the white powder like flour that covers their bodies. They usually gather in large groups that initially look like thick white mushrooms. Mealybugs can multiply without mating, so they multiply rapidly.

They secrete honeydew that attracts ants as they eat, adding sticky residues to the wax powder. The mealybug attacks many plants, but citrus trees, fruit trees, and houseplants are often targeted.

Scale insects.

It is closely related to the mealybug and comes in a variety of colors, including powdery white. The female cotton-bearing scales carry a large cotton pouch – two to three times longer than the body of the scales.

When collected for feeding, they look like lumps of cotton wrapped around the stems and leaves. When immature scales molt, they litter the foliage with white skin like cotton. These cotton-like white scales also produce a large amount of honeydew.


The whitefly is a small winged pest coated in waxy white powder. Like their relatives of mealybugs, they multiply rapidly. White powder on the leaves of lemon trees often comes from this pest.

The whitefly gathers on the underside of the leaves, creating a blanket of insects, waxy silvery-white flakes, and sticky honeydew. Gently shake the affected plant and the “powdery white thing” flies. When the shock stops, the pest returns.
