ABSTRACT=<p>Microbial lifeforms associated with land plants represent a rich source for crop growth- and health-promoting microorganisms and biocontrol agents. Volatile organic compounds (VOCs) produced by the plant microbiota have been demonstrated to elicit plant defenses and inhibit the growth and development of numerous plant pathogens. Therefore, these molecules are prospective alternatives to synthetic pesticides and the determination of their bioactivities against plant threats could contribute to the development of control strategies for sustainable agriculture. In our previous study we investigated the inhibitory impact of volatiles emitted by <italic>Pseudomonas</italic> species isolated from a potato field against the late blight-causing agent <italic>Phytophthora infestans</italic>. Besides the well-documented emission of hydrogen cyanide, other <italic>Pseudomonas</italic> VOCs impeded <italic>P. infestans</italic> mycelial growth and sporangia germination. Current advances in the field support the emerging concept that the microbial volatilome contains unexploited, eco-friendly chemical resources that could help select for efficient biocontrol strategies and lead to a greener chemical disease management in the field.</p>
