Botryosphaeria dieback is a grapevine trunk disease with a worldwide distribution and associated with Diplodia seriata and Neofusicoccum parvum among several other Botryosphaeriaceae species. The aforementioned xylem-inhabiting fungi cause wood lesions, leaf and berry symptoms and eventually lead to the death of the plant. The aim of this work was to develop a simple model system to reproduce the...

Liquid chromatography-diode array screening of the organic extract of the cultures of 13 isolates of the fungus Neofusicoccum parvum, the main causal agent of botryosphaeria dieback of grapevine, showed similar metabolites. One strain was selected for further chemical studies and led to the isolation and characterisation of 13 metabolites. Structures were elucidated through spectroscopic...
