Antimicrobial Potential of Six Plant Essential Oils Against <i>Pseudomonas syringae</i> pv. <i>actinidiae</i>: <i>In Vitro</i> Activity and <i>In Planta</i> Efficacy Do Not Always Align.

ABSTRACT: Plant essential oils (EOs) are attracting interest as ecofriendly alternatives to antibiotics and copper-based control of kiwifruit bacterial canker (KBC), caused by Pseudomonas syringae pv. actinidiae (Psa). This study chemically profiled six EOs (anise, basil, cardamom, cumin, fennel, and laurel) and evaluated their antimicrobial activity both in vitro and in planta. The in vitro assay targeted four strains, two of Psa and two of the low-virulent P. syringae pv. actinidifoliorum (Pfm), whereas the in planta assay focused on the highly virulent Psa7286 strain, assessed under preventive and curative application regimes (i.e., 14 days pre- or post-inoculation, respectively). Cumin, with cuminaldehyde as its
