AB [EN] Trichoderma is a genus of fungi used for the biological control of plant diseases and a largenumber of its bio-formulates are available in the market. However, its efficacy under field conditionsremains unclear, especially for the protection of grapevine plants against Grapevine Trunk Diseases(GTDs). These diseases are caused by a complex of fungal pathogens whose main point of entranceinto the affected plants is through pruning wounds. In this research, different Trichoderma nativestrains have been evaluated according to their ability to grow at different temperatures and theircapacity to colonize pruning wounds in adverse climatic conditions. Strains from section Trichodermahave adapted to cooler conditions. On the other hand, strains from clade Harzianum/Virens growat higher temperatures. However, differences can also be found between strains inside the sameclade/section. Native strains were able to colonize more than 70% of vine pruning wounds in winterconditions. The Trichoderma strain T154 showed a significantly higher re-isolation degree from vineplants and its concentration was optimized for spraying onto vine plants. In conclusion, Trichodermanative strains are better adapted to survive in a changing environment, and they could give betterprotection to grapevine plants in co-evolution with each specific vineyard
