This article is written for the person who has an understanding of how mycorrhizae, thrichoderma, and rhizobacteria work with plant growth and plant communities. For those needing a refresher course you can see great videos here:
Here is a great video about how mycorrhizae fungi can enable communication and cooperation between trees in a forest.
Here is a great video showing how rhizobacteria change the physiology of cucumber plants which stops beetles from feeding and thus controls bacterial wilt spread by the beetle.
After watching those videos you should be able to see the importance of combining different genus as well as species in the same mix to maximize the interactions between the microbial community and the plant community. Science is just starting to focus on these processes. The research so far is very positive as is the results people are getting from using these products.
Now that you are committed to mycorrhizae, trichoderma, and rhizobacteria you need the best brand possible.
Trichoderma is a major fungal antagonist
It reduces fungal pathogens to suppressive levels. This is when the disease is present but no apparent damage can be observed.
In their defensive actions, Trichoderma spp. apply lytic enzymes (Kubicek et al. 2001; Viterbo et al. 2002), proteolytic enzymes (Kredics et al. 2005; Suarez et al. 2007; Chen et al. 2009), ABC transporter membrane pumps (Ruocco et al. 2009), diffusible or volatile metabolites (Calistru et al. 1997; Eziashi et al. 2006), and other secondary metabolites (Reino et al. 2008)
They succeed by their impairing growth conditions of pathogens
