Abstract
Plant diseases are a major cause for yield losses and new strategies to control them without harming the
environment are urgently needed. Companion planting contributes to the plant health in diverse ways,
among which the emission of disease-inhibiting volatile organic compounds (VOCs). Here we report
VOCs emitted by companion plants can be used as chemical signals providing better quality for
strawberries during the hydroponic culture. In a separate paper, we reported that the VOCs of
companion plants caused strong growth stimulation of the strawberries. This work focuses on VOCs
released from companion plants and demonstrates the high in plant protective potential of VOCs, which
prevented gray mold disease in strawberries without phytotoxic effects, in contrast to other fungicides.
This work brings new perspectives for plant protection against the devastating pathogen of strawberries.
