Rayamajhi, M. B.; Pratt, P. D.; Klopfenstein, N. B.; Ross-Davis, A. L.; Rodgers, L. 2013. First report of Puccinia psidii caused rust disease epiphytotic on the invasive shrub Rhodomyrtus tomentosa in Florida. Plant Disease. 97(10): 1379.
Rhodomyrtus tomentosa (Aiton) Hassk. (downy-rose myrtle, family: Myrtaceae), of South Asian origin, is an invasive shrub that has formed monotypic stands in Florida (3). During the winter and spring of 2010 through 2012, a rust disease of epiphytotic proportion was observed on young foliage, stem terminals, and immature fruits of this shrub in natural areas of Martin and Lee counties, Florida. Expanding leaves and succulent stems developed chlorotic flecks on the surface that developed into pustules and ruptured to discharge urediniospores.
