The only
point I was trying to make was the availability of opinions and products
outside of the posters in this group. I was
trying to resource another group member. We found that a number of AM products
on the market were long winded on sales and short on spore count. Since I am
not a scientist, I have followed Dr. Mike’s lead and taken Pinus spp from devoid
of AM to a high percentage of colonization. It’s been obvious through this
process that some species colonize while others have not. I was trying to suggest

Message----- Hi Laura, I got a good
chuckle out reading how far off base Tom J., was in his opinion about AM fungi
with grapes. I know Mike Amaranthas and he's a personable guy, but his
research has been mainly dealing with ectomycorrhizal fungi which have little
to do with benefiting grape plants. Mike does make a rather strange
endomycorrhizal fungi inoculum in tablet form. A local mycologist at
Eastern Washington University who's specialty is working with AM fungi tested
those tablets and found little to do with endomycorrhizal fungi and a lot to do
with fertilizer. Dr. Ted Saint John would have fun ranting and raving
about that one. :) It looked
like Tom J was trying to say there was a specific species of mycorrhizal fungi
that works with grape plants. To be blunt, that's ridiculous. Any
of the 56 odd glomus species of endomycorrhizal fungi will colonize grape
plants. When you get into endomycorrhizal fungi and try to say that only
a specific species will benefit grape plants or another specific species will
benefit a tomato plant, etc., that claim is outside the realm of known research
on the topic of endomycorrhizal fungi. It's fairly safe to say that
endomycorrhizal fungi species are not plant species specific. In fact
research states that under the right biological conditions AM fungi will grow
into the roots of all terrestrial plants. To turn that around a bit, it
is also safe to say that grape plants are NOT benefited only by a
single species of endomycorrhizal fungi. That's a claim out of the past
that simply doesn't stand up to research findings or reality out in the soils. Compost Tea grant program.
