Not all products are equal and some have no mycorrhizae at all. Some ended up containing more fertilizer that is legally allowed with out proper labeling.

Endo is the type not the brand.

Above the charts there is a line about Western Labs opinion that '30' is a good count. Possibly other companies want to shoot for that mark. For only $30 you can test a product yourself.

Glenn,
You can either buy Endo (for leafy plants) or Ecto (for woody plants such as trees)

A great blog post about commercial mycorrhizae. Research is proving most are worthless. Informative and fact based opinions from University of Minnesota's Jeff Gillman:

One of our vendors (Grigg Brothers) produces extreme high quality liquid foliar fertilizers. They've wanted to expand into granular for a while so last year they hired one of the guys who developed M-Roots (Kevin Burroughs). Kevin & I spent a lot of time together last summer developing a line of meal based (no manure) organic fertilizers.

I've been lucky. A former business partner & I were permitted to do some postgrad work at Yale Sch of Forestry where we met many of the notable soil biologists who pioneered mycorrhizal ferts.

Griggs soon learned the meal base (Lipoproteins) stimulated background mycorhizzae more than most prepared inoculants. Therefore the brothers wanted to market the lipoprotein base without mycorrhizal inoculant. When it came to newly disturbed building sites I disagreed. Dead soil still benefits from inoculation.

I asked for third party independent validation of the Griggs discovery. This I got but then came the news blackout...until last month.

The Griggs (in conjunction with PlanTTech & Gold Starr) had been testing all of the common inoculated granular organic ferts. What they discovered is alarming. Some inoculated products aren't. Others don't contain enough to perform. Most were around 20-40% of what they should have been.

I'm not going to "OUT" anyone yet so please don't ask. When the time comes the owners of the data will decide whether they want to go public.

I do use this product, but the testing doesnt really mean anything to me unless this was done by a completely outside and unbiased source. Who sent in the different samples? and who sent in ''your'' sample to a@L labs?

Was it a outside source that did this testing from a random bag of your product? Or was it your company that sent your own sample in along with the others for comparison? '' see what Im saying?''
I would think most companies that did testing like this with other products to compare to there own might just make sure to beef there sample up a bit with maybe some really high levels.,,,

Not to say your doing that, but if it was from a outside source getting the samples at random then it would hold more merit in my book.

I had this confused with a different product out, until I took the time to re read it, and seen that it was pumpkin pro AM120, which is the only mycorrhizal I ever use. Just ask Tom!,,lol

I had trouble getting anything out of that article on reforest.com. There were only four sentences of text and two of the three graphs had no label for the Y axis. I have no ideas what the quantities represented. On top of that Wallace's name is spelled incorrectly. I think it needs a rewrite.
