The way I
understand it tobacco rattle virus is hosted by soil nematodes. This means that
removing and destroying the plant doesn't solve the problem, because the virus
is still present in the soil it was removed from. It can also spread very easily
by contact with other plants. Tobacco rattle virus is a serious threat to a
garden, and no plant showing symptoms should ever be brought into one. If it
turns up, get rid of the plant immediately, sterilize the soil it was in, don't
plant anything there for a year or better yet two years, and clean your hands
thoroughly before touching any other plants. I don't think there is any
cure for it. Nematicides would be a good idea, but they are not easy to get
Subject: Re: [hostapix] Tobacco rattle
You are confusing me a little here.
While there could be , I suppose, a link between viris incidents, and
Nemotode infestations, I was not aware that it had been researched.
Once a hosta has viris symptoms in evidence, getting rid of any
nemotodes would not change that part of the problem. Can you clarify
your thinking for me.
Tobacco rattle virus.....One the
better reasons to grow plants in containers. Nematodes don't seem to
do well in a soiless mix. Last year was particularly GOOD for
nematodes and this may translate to more frequent appearances of viral
infections. Does Dr. Lockhart have a recommended cure? Wonder if
you cut it way back, stuck it in a container and treated it with a
nematicide if this would have any positive impact on the plant?
