Inactivation of Radish Yellows Fungus, Fusarium oxysporum f. sp. raphani through Aerobic or Anaerobic Fermentation of the Radish Residue

Abstract

Radish residue infested with radish-yellows fusarium was piled up for 20 days to examine for inactivating effect on the pathogen. No Fusarium oxysporum was detected in the tissue samples collected from the lower parts of the pile without plastic-film cover, from the parts where temperature rose up more than 50C, and from almost all parts of the pile covered with plastic-film even though temperature ranged from 15 to 35C. These results suggest that F. oxysporum is well inactivated under the conditions of anaerobic fermentation.
