Rot

[George R. Stilwell, Jr.]

Russell,

I think that  sounds typical? It's hard to remember since I haven't had any
rot since I stopped buying plants from Chen Yi many years ago.

Phytophthora root rot in woodies is not like that. The leaves just wither
and turn yellowish, finally dropping off and that stem never grows again.
Eventually the entire plant dies.

As I said, I have no idea if Messenger will work on Arisaema against the
pathogens distributed by Chen Yi. It works well for cotton, corn, and other
cash crops. It has worked for me in certain Rhododendron, but not all
varieties. I worked wonderfully in a Taxus brownii as well.
