Pathogens controlled

So far as the author is aware, different strains of Trichoderma control every pathogenic fungus for which control has been sought. However, most Trichoderma strains are more efficient for control of some pathogens than others, and may be largely ineffective against some fungi. The recent discovery in several labs that some strains induce plants to "turn on" their native defense mechanisms offers the likelihood that these strains also will control pathogens other than fungi.

The link below shows a study of T22 on tomato seedling growth as a added benefit. Ami

Yes, I read that at the Cornell site and that's why I made the comment about other possible benefits.

I also read that acta link you posted but all they were doing was comparing growth of the same variety with and without Rootshield, and we don't have the data, and it was done in a greenhouse and heaven knows what other variables might be at work outside in what I call the DIRT, or in containers.

I'm not trying to discourage anyone here, but Rootshield has been suggested for the control of primarily systemic diseases and primarily for the control of Damping Off.

So I'll be waiting patiently for your reports next year.
