Jim,
That is interesting. Particularly because Phytophthora (Root Rot) is a
serious problem here in North Carolina particularly for Rhododendron. I'v=e
tried all the usual chemicals like Subdue drenches with little success.
The best treatment has been Messenger (developed at Cornell). While other
treatments delayed the death of a plant, Messenger has actually revived
plants of both Rhododendron and Taxus that were badly infected and they'r=e
still healthy several years later.
Messenger supposedly activates a gene in the plant that lets it fight off
diseases. Whether this would be so for Arisaema rust I have no idea.
One of the AEG group was going to try Messenger on Arisaema rust, but I
can't remember who it was. Fortunately, knock wood, I have no Arisaema ru=st
to experiment with. (please, don't send any you guys).
But using dyes is certainly an interesting idea.
