In Cabernet Sauvignon, EBR delayed pathogen establishment by modulating stomatal closure and boosting antioxidant enzymes (superoxide dismutase, catalase, ascorbate peroxidase, peroxidase) and pathogenesis\u2010related proteins (chitinase, \u03b2\u20101,3\u2010glucanase). Ecolly exhibited inherent resistance, characterized by localized hypersensitive responses and elevated salicylic acid (SA) and jasmonic acid (JA) levels post\u2010EBR treatment, which amplified systemic acquired resistance (SAR) via upregulation of\n                    <jats:italic>PAD4<\/jats:italic>\n                    ,\n                    <jats:italic>EDS1<\/jats:italic>\n                    , and\n                    <jats:italic>PRs<\/jats:italic>\n                    genes. Stomatal regulation in Cabernet Sauvignon correlated with EBR\u2010induced abscisic acid (ABA) dynamics, while Ecolly maintained constitutive stomatal defense. Transcriptional analysis revealed cultivar\u2010specific phytohormonal interplay, with SA pathways dominating in Ecolly and delayed SA accumulation in Cabernet Sauvignon. These findings demonstrate that EBR enhances resistance through multifaceted mechanisms\u2014pathogen inhibition, redox homeostasis, hormonal signaling, and genetic priming\u2014with efficacy modulated by genetic background. This study underscores brassinosteroid as a sustainable tool for integrated disease management in grapevines.\n
