The morphological and cultural characteristics of the isolate allowed it to be classified as <em>Plectosphaerella melonis</em>. BLASTn analysis revealed 99% homology of the ITS sequence from the isolate with 14 <em>Acremonium cucurbitacearum</em> and <em>P. melonis</em> isolates, allowing attribution of the isolate to <em>P. melonis</em> (syn. <em>A. cucurbitacearum</em>). Koch’s hypothesis requirements were fulfilled for the isolate. Symptoms on host roots developed after 14 d of growing cucumber plants on infested soil. Plants of the cucumber variety Nizhynskyi 12 were very susceptible at the two leaf growth stage (2 weeks after sowing). Above-ground disease symptoms were absent after 14 d, even with severely diseased roots. This is the first report of <em>P. melonis </em>on<em> C. sativus</em> in Ukraine.</p> ER -
