An exclusive symbiosis interaction of Mychorizes and Trichodermas ensures the plants develop healthily and become disease-tolerant to fungal and wood diseases.


Microscopic fungus improves the development of the vine root through symbiotic action : the plant absorbs nutrients more easily, strengthening the plant root which  builds up its own defence. It also increases its defence mechanism against root pathogens. 


Microscopic fungus found in soil grant the plant an improved defence barrier against wood disease due to competition and parasitism. 

An exclusive blend of various trichodermas strains are used by the Pepinieres Guillaume to reinforce the effect.
