Arisaema Rust

From: mossytrail at hctc.com (mossytrail) on 2008.05.02 at 01:09:15(17526)
Is there any known fungicide against the orange-dot rust
affecting Arisaema leaves?

This is not a fungus! It is a rust, and this seems to be a bad year for it
as many of the May Apples here in the Cincinnati area are showing it.

Okay, so (I'm showing my ignorance here) what sort of
organism causes rust? Is it a virus, a bacteria, something
else? And to rephrase my original question, is there any
known effective treatment?

Jason, Vic, et al.
Actually rusts are a type of fungus, order Uredinales, which
are typically host-specific parasites. Sometimes there are two hosts
depending on the stage of the life cycle, perhaps the most well known
being cedar/apple rust. Definitely fungus though. As to the specifics
of the Arisaema rust, including any treatments, we'll have to go to
someone who's worked with this species or group.
