Pathogenicity tests of Fusarium. commune 16-560, Fusarium. oxysporum 19-385, and Fusarium. proliferatum 17-073. Onion seeds (Allium cepa L. cv. Hwangryongball) were soaked in the conidial suspension (8 × 105 conidia/mL) of each isolate for 90 min and planted in pots. Pots without the tested pathogens were used as controls. At 12 days after inoculation, photographs were taken (A) and seedling survival rate was measured (B). different letters on bars indicate significant differences according to Tukey’s test (p < 0.05). (C) Mycelial agar plugs from PDA cultures of each isolate were inoculated on the vertically cut basal plates of onion bulbs. Agar plugs without mycelia were used as controls. Photographs were taken 8 days after inoculation.
