| Abstract | Crown and root rot is a disease of asparagus caused by the fungal pathogen Fusarium oxysporum. We investigated several asparagus fields in Gangwon Province, confirmed a high incidence of crown and root rot of asparagus seedlings, and isolated pathogens from the asparagus seedlings. Based on the sequence analysis of the translation elongation factor 1, we confirmed that F.oxysporum is the most prevalent fungus causing disease in asparagus plants. We selected six fungicides (thiophanate-methyl, propiconazole, prochloraz, mancozeb, azoxystrobin, and kresoxim-methyl) and examined their effectiveness on the inhibition of mycelial growth of F. oxysporum isolates. Prochloraz was the most effective fungicide showing >90% inhibition of mycelial growth at a concentration of 0.1 µg/mL. Propiconazole was also a highly effective fungicide with approximately 97% inhibition of mycelial growth at a concentration of 10 µg/mL. Mancozeb was the least effective fungicide with <10% inhibition of mycelial growth at a concentration of 10 µg/mL and approximately 43% inhibition at a concentration of 100 µg/mL. |
