Megjegyzések:	BackgroundGrapevine trunk diseases are one of the most prevalent diseases of the vineyard worldwide, caused by a variety of fungal pathogens. Mycoparasites, like Trichoderma are biopesticides against GTD pathogens.ObjectivesThe aims of this study were taxonomical identification of ten Trichoderma sps. from asymptomatic plants in the Tokaj wine region the determination of mycelial growth rate at different temperatures, the mycoparasitic potential against Diplodia seriata and Neofusicoccum parvum and field experiments with the mixed Trichoderma spore suspension.MethodsThe Trichoderma isolates were identified based on their ITS1,2 and tef1 marker sequences. Their mycelial growth was determined from the two average colony diameters on PDA, measured for each Trichoderma isolates for 4 days.The mycoparasitic ability was detected according the method of Szerekes et al (2006; Journal of Microbiological Methods, 619-622).Some GTD symptomatic plants were treated with Trichoderma spore suspension in 2014. The treated trunks were checked monthly.ConclusionsThe ten isolates belonged to three species: T. harzianum (TR01-05, TR07, TR09-10), T. orientalis (TR06) and T. viride (TR08).The Trichoderma isolates showed different mycelial growth rate on different temperatures (5 - 37?C). The T. orientalis (TR06) and T. harzianum (TR05) isolates showed the highest growth rates within the whole temperature range, and their growth rates were especially high at 30 and 37?C.All Trichoderma overgrew the GTD pathogens, and sporulated on their colonies, therefore their Biocontrol Index was 100%.The symptoms decreased on all treated samples, except one. Moreover the Trichoderma strains could be reisolated from their woody tissues.
