Urban Farm DB summary
In July 2021 and July-October 2022, rust disease was observed on all 20 lemongrass plants in a community garden near Mankato, Minnesota, USA, causing 5-50% leaf loss. Molecular analysis of the rust fungus identified it as Puccinia cesatii or a closely related species. Although P. cesatii has been reported on Cymbopogon species, lemongrass is not generally considered a host, indicating an unusual infection.
