Search for plant-based biofungicides against toxigenic contaminants in barley (Hordeum vulgare L.) forage in hydroponics

Abstract: The methanolic extracts of Trichoderma asperellum culture filtrates revealed an important inhibition on mycelial growth, sporulation, germination and on the disease reduction on leaf discs of potato inoculated with each of the two isolates of Phytophthora infestans. The 2H-Pyran-2-one-6-pentyl compound could be responsible for the fungicidal activity.
