| Rust Diseases or Rust Fungus
occurs on
a wide variety of plants, including Plumeria. In general, however
and given rust is rather specific in its host range. Many rust
have
several kinds of microscopic spores. With such forms, the fungus
may infect two entirely different plants living part of the year on one
host and the remainder of the year on the other. (which in the case
with
plumerias) The presence of a rust disease can always be
determined
be the appearance of yellow, orange or reddish-brown powdery pustules
on
the leaves, stems, or buds of the infected plant. The spores
produced
in these pustules are carried by splashing rain or air currents to
near-by
healthy plants where new infections will occur.
Rust Fungus does not kill Plumerias, but can rapidly
de-foliate an
entire tree.
