- Abstract
Puccinia psidii is native to South and Central America and the Caribbean, where it causes a serious leaf and shoot disease of a wide range of Myrtaceae. These include the native Psidium guajava (guava) and introduced Eucalyptus species. In 2002 a rust fungus was observed causing severe damage to 1-year-old trees during a routine disease survey of Eucalyptus globulus in Uruguay. The rust produced egg-yolk yellow pustules on the leaves and resulted in shoot-tip dieback. The characteristic pustules and morphological examination of uredinia and urediniospores showed that the fungus was indistinguishable from Puccinia psidii. Puccinia psidii has previously been reported in Uruguay on native Myrtaceae.
