Pathogenicity of Phytophthora palmivora to fig fruits after its long-term storage in water

  • Noriyuki MiyakeEmail author

Long-term storage methods for Phytophthora palmivora were tested using five isolates stored in sterile distilled water (SDW) for up to 6 years and 8 months, and their growth and virulence were evaluated. All five cultures remained viable in SDW at room temperature and retained normal mycelial growth characteristics and morphology. All but one culture formed normal zoospores, and all five were still pathogenic to fig fruits. These findings suggest that this SDW storage is a simple, inexpensive method for long-term preservation of the pathogenic oomycete in the laboratory.
