Abstract

Roses (Rosa spp.) are widely cultivated in Italy for ornamental and aesthetic purposes. In autumn 2020, petal brown spots on rose buds especially on petals were observed in outdoor potted plants in Tuscany (Italy), causing aesthetic damage compromising marketability of cut flowers. A study about morphological and phylogenetic features of the disease-associated fungus, followed by a pathogenicity assay according to Koch's postulate, was carried out. The recently described Fusarium clavum (FIESC 5) was found to be the causal agent of petal brown spot disease on rose buds in Tuscany, Italy.
