Rot

[Russell Coker]

(Sigh)

I think you are right.  I'm going to try the Messenger, and keep drenching
with Subdue (although I don't think the particular problem I mentioned is
starting in the soil).  Remember, here on the Gulf Coast, we measure rain in
feet per year, not inches.  I use Daconil, Strike, Banner Max, and Protect
on daylilies for rust.  Two are contact and two are systemic - so I might as
well hit the Ariseamas too.

By the way, the only Arisaemas affected were rhizomatus tropicals, and they
were healthy and happy - then dead.
