Researchers from University M’Hamed Bougara of Boumerdes (UMBB) recently published a study in European Journal of Plant Pathology highlighting an innovative, eco-friendly approach to plant protection that aligns with ASTER’s mission of promoting sustainable agriculture. The team investigated volatile organic compounds (VOCs) produced by Trichoderma species isolated from olive grove soils and their ability to suppress Verticillium dahliae, a soil-borne pathogen causing wilt in tomato, olive, and other crops.
Laboratory experiments showed that VOCs emitted by these fungi significantly inhibited pathogen growth. GC-MS analysis identified bioactive compounds—including monoterpenes and phenolics—known for antifungal properties. Beyond direct inhibition, these VOCs may also stimulate plant defense responses, supporting healthier crops.
For ASTER, these findings emphasize the potential of biological control strategies to reduce chemical pesticide use, enhance soil biodiversity, and strengthen crop resilience. Leveraging naturally occurring soil microbes and their metabolites offers a path toward sustainable disease management in Mediterranean agroecosystems.
This research lays the groundwork for developing VOC-based biocontrol tools, demonstrating how scientific innovation by UMBB can advance agroecological practices.
