Puccinia malvacearum on Pelargonium geranium

Puccinia malvacearum, also known as hollyhock or mallow rust, is a fungal species within the genus Puccinia known for attacking members of the family Malvaceae. An autoecious pathogen, it can complete its life cycle using a single host.

It was originally found on the leaves of a species of Malva in Chile. ^[3] Other plants also affected by the rust include Abutilon , Alcea (Hollyhock), ^[4] Hibiscus , Lavatera , Malvastrum and Sphaeralcea .

Suggested control measures (in the US), include sanitation (removal or destruction of affected plants or plant portions) or treatment with fungicides.
