Vegetal residue‐based formulation of <i>Trichoderma ossianense</i> , a new indigenous vineyard species adapted to alkaline <scp>pH</scp> with potential biocontrol ability against Black‐foot disease pathogens

This study opens up a wide range of possibilities for the protection of vineyards in areas with alkaline pH, as well as for the prevention of Ilyonectria sp. and Dactylonectria sp. in nurseries and young vineyards using vegetal residue-based formulations of T. ossianense. These results highlight T. ossianense as a reliable, safe, and promising biocontrol agent against grapevine Black-foot disease. © 2025 The Author(s).
