I reviewed my notes from Janice Uchida's talk at the ASHA convention in
2001. I seem to recall she said that the mycelium stage infects the host
bodily. By the time we see the effects of this infection the host is toast,
the mycellium has gone on to produce fruiting bodies by the time we see
sunken spots (or whatever) and has spred spores. These spores spread to
adjacent plants and poof. She told of how whole GHs of Hawaiian cut flower
dendrobiums will wilt overnight into mush. She said prevention is the cure,
via cleanliness.

I have no idea whether that helps Steve out.

Funginex is now sold by Ortho as "Rose Pride Rose & Shrub Disease Control".
The active ingredient is the Triforine that Pat Brennan thought was no
longer in production. (present at 6.5%).

According to package directions it can be mixed with Ortho Malathione Plus
and Ortho Diazinone Ultra - follow label rates.

I will search to see if triforine is systemic or not. I'm betting 'not'.

This term "microfungus" is new to me. I looked at the pictures on Steve's
website again with this is mind and wonder why there seems to be so many
different expressions of damage? It is hard to see all of the various
damage symptoms as common to one organism, but I suppose it is possible.
I
did a websearch and found a few bits of information. I want to know
whether
this is an organism that lives IN and spreads though the plant or if it
live
ON the plant's surface tissue. Fungi, as I understand them have several
life stages. At some point it has to reproduce and would make fruiting
bodies at the surface of the leaf that would spread it to new plants. If
the "mycelium stage" of the fungus lives inside the plant and travels from
cell to cell than wouldn't you need to target it with some kind of
systemic
fungicide that the plant could absorb rather than a topical fungicide
that?
Is it living off the tissue like a parasite or just clogging transport of
nutrients and water as it grows from cell to cell, and tissue type to
tissue
type etc?

How is a microfungus different from the regular fungus that we as orchid
growers are always battling? (You know, the stuff we call 'rots' and
which
could as likely be a bacterial infection.)

Is Physan systemic? I know it kills spores on surfaces but would it have
any effect on fungus growing inside and being protected by the plant
tissue
from coming into contact with the chemical? This may be the reason behind
the cocktail idea, one to kill the spores outside the plant and one to
kill
the actual fungus inside the plant. Daconil is systemic, right? Is there
another reason why a cocktail is necessary? (We don't really know what it
is so we hit is with everything we've got?) :-)

You don't necessarily have to MIX the chemicals to have them both
available
for use. You might be better off to separate their application by a few
days to produce the desired effect.

Ray,

I am in agreement with Aaron, I think Steve has a microfungus. I was
guessing that before I even saw the pictures. I have had microfungus on
phals, I have cured it. But the only way I have successfully cured
microfungus is using a cocktail of chemicals. Two months ago when I
mentioned a cocktail Aaron replied with a post about not mixing
chemicals
under the risk of toxic precipitate and wrecked buffers. Not wanting to
hear this crap again, I took my discussion with Steve out of the group.
I
just find it maddening that today Aaron is giving pointers to sites
promoting chemical cocktails.

Pretending that you know more then the chemical manufactures or the
directions supplied with the chemicals does a disservice to this group.
Is
the label that comes with the chemical the "precise knowledge" we must
know
or is there more? If we follow the label are we still going to create
toxic
precipitate? If I am Steve, who or what do I believe?

Chemical labels includes a section on compatibility and yes you better
read
them and follow the directions. Randomly mixing any chemicals is a dumb
idea. But, when you take copper out of the mix, it seems that most of
the
chemicals I commonly use are compatible. I am not making that up, it is
what the labels say, it is what experience has shown. Some of the more
common cocktails are even marketed as a single product, Spectro and
Banrot
to name two.

BTW, I highly recommend Spectro which is a cocktail of 3336 and Daconil
as
a
broad spectrum fungicide.

Sorry about the double post, I would blame my ISP but who would believe
me.
