| description | <i>Vitis vinifera</i> is highly susceptible to grapevine trunk diseases, with <i>Neofusicoccum parvum</i> recognized as a highly destructive pathogen. This study investigates the biocontrol potential of five <i>Trichoderma</i> species (<i>T. harzianum</i>, <i>T. viride</i>, <i>T. asperellum</i>, and <i>T. virens</i>) against <i>N. parvum</i>, evaluating multiple biocontrol mechanisms (mycoparasitism, competition for nutrients, production of volatile organic compounds (VOCs), and antibiosis) as well as their compatibility with the fungicides copper oxychloride and sulfur. Results demonstrated that (1) <i>Trichoderma harzianum</i> effectively suppressed <i>N. parvum</i> through VOC production, mycoparasitism, and nutrient competition, significantly reducing pathogen growth <i>in planta</i> while showing compatibility with both fungicides, highlighting its suitability for integrated disease management; (2) <i>Trichoderma viride</i> showed high inhibition of <i>N. parvum</i> in vitro, but its phytotoxicity <i>in planta</i> limits its field application. These findings support <i>T. harzianum</i> as a promising agent within integrated disease management strategies, offering a sustainable alternative to reduce chemical fungicide reliance in controlling grapevine trunk pathogens. |
