<div><br></div><div>Wood vinegar is a liquid mixture with organic properties that results from the condensation of smoke produced by the pyrolysis of wood and its residues during processing. Its chemical composition varies depending on the plant material used. In addition to improving soil quality and regulating plant growth, it also controls fungal plant diseases. This study was conducted to analyze the antimicrobial effect of vinegar obtained from the wood parts of poplar (Populus nigra, P. alba). The effects of wood vinegar on Botrytis cinerea, the causal agent of gray mold in tomatoes, and Sclerotinia sclerotiorum, the causal agent of root rot in sunflowers, were evaluated. It was observed that different concentrations of wood vinegar inhibited the mycelial growth of the pathogens in a dose-dependent manner. Fresh mycelium discs of B. cinerea and S. sclerotiorum were placed on petri dishes containing wood vinegar at different concentrations (0.2% mL, 0.5% mL, and 0.7% mL) in vitro to examine the effects of wood vinegar. It was found that all doses, except the 0.2% mL (16.66%) concentration, completely halted the mycelial growth of S. sclerotiorum (at 0.35%). For B. cinerea, the mycelial growth inhibitory dose was determined to be 0.65%. The study showed that wood vinegar significantly inhibited the mycelial growth of both pathogens and could potentially serve as an alternative to synthetic fungicides.</div>
