This is the most common cause of white, flour-like patches on Asiatic lily leaves. It thrives in high humidity and poor air circulation around the dense foliage of 'Amiga' lilies.

Very Common

Botrytis Lilia (Lily Botrytis)

While often characterized by brown spots, early stages or certain moisture levels can cause a fuzzy, light-colored growth on the petals and leaves. It is common in humid environments where moisture lingers on the blooms.

Scale Insects (Lepidole scales)

Some species of scale can appear as small, white, waxy bumps on the stems and undersides of leaves. These insects secrete honeydew, which may lead to secondary growth.

Common
