The root of your success

Trichoderma asperellum T34

ASPERELLO® T34 Biocontrol® is a biofungicide which contains the antagonistic fungus Trichoderma asperellum strain T34. It has multiple modes of action. ASPERELLO® colonizes the roots, forms a barrier against pathogens and supports healthy root growth; ASPERELLO® triggers the plant’s natural defense mechanisms and it parasitizes and actively kills pathogens.
It is used in a preventative way to protect ornamentals against the major root diseases, including Fusarium, Pythium, Phytophthora and Rhizoctonia.
