ABSTRACT
During a survey conducted in Hamedan Province, Iran, Thompson seedless grapevine (Vitis
vinifera) bunches were observed exhibiting symptoms of brown ripe rot. To identify the
causal agent, samples were collected, and fragments from the infected tissues were cultured
on PCA and PDA media. Morphological studies and sequencing analyses of the ITS region
were performed to identify the emerging fungus. To confirm the pathogenicity of the fungal
isolate, Koch’s postulates were applied. Based on morphological assessments, pathogenicity
test, and the ITS sequences, the causal agent was identified as Arthrinium sacchari
(Apiosporaceae, Sordariomycetes). This study provides new information on ripe rot caused
by A. sacchari in grapevine plants.
