Evaluation of the antifungal activity of the protein and non-protein extracts of Trichoderma asperellum and Trichoderma atroviride culture filtrates against Phytophthora infestans


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.
