Nine strains of the fungus Phomopsis spp. were isolated from a vineyard showing decline from the disease esca. Strains were screened for their ability to produce secondary metabolites showing chemical diversity. The culture extracts of each strain were analyzed by liquid chromatography–ultraviolet–diode array detection–mass spectrometry. Three strains were selected for the isolation and...
