Re: Impatiens Downy Mildew, read it & weep

**W*@aol.com**

At the Smithsonian In-Service Training talk today on plant diseases,  
Impatiens Downy Mildew was described in details. It stays in the soil for  up to 
5 years. Worse is that Jewelweed is a vector plant and that is  found up and 
down the East Coast :-(.

Basically, pull, bag, and dispose of any diseased plants at first sign. Do  
NOT re-use their pots or soil. He recommended a few chemicals for  
applications, but none seemed effective or worth the bother.

They are  urging everyone (including commercial wholesale operations) NOT 
to grow it for  at least a year. Unrealistic, IMHO.
