Zoosporicidal metabolites from an endophytic fungus Cryptosporiopsis sp. of Zanthoxylum leprieurii

► Two polyketides and one natural pentacylic petide were isolated from the fungus Cryptosporiopsis sp. ► The isolated compounds showed potent zoosporicidal activities against the downy mildew pathogen zoospores. ► These compounds have high potentials for practical use as natural pesticides against phytopathogens.
