In this study, the antagonistic potential of some strains of the genus Trichoderma isolated from grapevine against these pathogens was investigated at the laboratory and greenhouse levels. In-plate confrontation assays showed that the selected Trichoderma strains could inhibit the mycelial growth of both taxa, being more effective against N. parvum. In the in vivo assays, the biocontrol activity of the mentioned strains against the pathogens, when applied either simultaneously or successively, was tested on both grafted plants and seedlings germinated from seed. The effectiveness of the treatments was evaluated by comparing biomass weight and vascular rot lengths data. In seedling trials, successive treatments resulted in higher root development and a lower colonization rate of the pathogens, especially against R. solani. In grafted plants, some disparity was observed against N. parvum: simultaneous treatments resulted in higher aerial biomass, but successive treatments resulted in higher root biomass and lower necrosis. Against R. solani, simultaneous treatments were clearly more effective, with higher root and aerial length values and lower necrosis. The obtained data suggest that the use of Trichoderma spp. isolates can constitute an alternative to conventional fungicides to control certain grapevine wood diseases. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.7 2022 AGRONOMY 16 / 88 = 0.182 2022 Q1 T1 PLANT SCIENCES 60 / 239 = 0.251 2022 Q2 T1 0.663 2022 Agronomy and Crop Science 2022 Q1 5.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martín Ramos, Pablo Universidad de Zaragoza (orcid)0000-0003-2713-2786 Casanova Gascón, José Universidad de Zaragoza (orcid)0000-0003-3009-0935 Julián Lagunas, Carmen González García, Vicente Universidad de Zaragoza (orcid)0000-0002-2535-6914 5011 500 Universidad de Zaragoza Dpto.
