White rust
Plants infected exhibit spots on the upper surfaces of leaves. These spots are initially pale-green to yellow in color and up to 5mm in diameter, but may turn brown as the tissue becomes necrotic. On the underside of the leaf, stems, and flower, spots develop into pink or white waxy telial clusters/pustules where teliospores develop.Pustules are able to form on any green tissue of the plant, but are most common on young leaves and flower bracts.
