How compatible are mycorrhiza and trichoderma?
Mycorrhiza is a state of symbiosis between plant roots and a fungus. Trichoderma is a totally other type of soil fungus: it grows near and on the root surface but does not form simbiosis. It acts as an antagonist to other soil fungi, such as pathogens, and therefore contributes to the protection of the plant from soil borne diseases. The scientific literature contains articles about synergism between trichoderma and mycorrhiza and about competition between the two. A rather confusing situation!
