Biosolutions from Native Trichoderma Strains Against Grapevine Trunk Diseases

[EN] Fungi of the genus Trichoderma show strong potential as biological control agents (BCAs) against grapevine trunk diseases (GTDs) through mechanisms like antibiotic metabolite production and lytic enzymes. This study evaluated the biocontrol activity of four native Trichoderma strains—T. gamsii...

This study evaluated the biocontrol activity of four native Trichoderma strains—T. gamsii T065 and T071, T. carraovejensis T154, and T. harzianum T214— against Phaeoacremonium minimum, Phaeomoniella chlamydospora, and Diplodia seriata. Culture filtrates obtained at 8, 16, and 24 days post-incubation were tested using antibiogram and mycelial inhibition assays. Strains T071, T154, and T214 effectively inhibited D. seriata, while T154 and T214 also suppressed P. chlamydospora. Nevertheless, the limited effectiveness of all filtrates against P. minimum suggests that antibiosis is not the predominant mechanism involved in its control. These findings highlight the potential of specific Trichoderma strains and incubation times to directly control GTD pathogens and support the development of scalable biocontrol solutionsSIThe authors declare that this study received funding from project “LOWPHWINE IDI– 20210391” “Estudio de nuevos factores relacionados con el suelo, la planta y la microbiota enológica que influyen en el equilibrio de la acidez de los vinos y en su garantía de calidad y estabilidad en climas cálidos” which was granted by the Centro para el Desarrollo tecnológico Industrial (CDTI), the Ministerio de Ciencia, Innovación y Universidades (Spain)MDPIProduccion VegetalEscuela de Ingeniería Agraria y Forestal2025info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://hdl.handle.net/10612/26296reponame:BULERIA.
