Rust on hollyhocks is caused by the fungal pathogen Puccinia malvacearum and impacts hollyhock leaves and stems. This fungus first appears on leaves as yellow, circular spots about 1/8 inch wide. These yellow spots enlarge and swellings develop on leaf undersides.
The cause has been identified as being a phytoplasma (a bacterium), transmitted by the native flax plant hopper. The hopper injects the bacterium into the leaf, while sucking the sap. Yellow-leaf is found in North and South Island, but is more prevalent in North Island (Boyce et al, 1951).
