New piperidinium surfactants with a benzyl fragment in the head group were synthesized and characterized. The critical micelle concentrations, degrees of binding of counterions, and aggregation numbers were determined for aqueous solutions of these surfactants by tensiometry, conductometry, and spectrophotometry. The wetting action of the synthesized surfactants was characterized, and their solubilization capacity with respect to the hydrophobic dye Orange OT and fungicide carbendazim was estimated. Antimicrobial activity of the surfactants to a number of plant pathogenic strains was revealed, which is especially pronounced with respect to gram-positive bacteria Clavibacter michiganensis, Curtobacterium flaccumfaciens , and Rathayibacter iranicus (minimum bactericidal concentration 0.5–4 µg mL −1 ).
