Other claims from this paper (9)
- Intervention effect Sterile culture filtrates of Epicoccum purpurascens applied before inoculation with Sclerotinia sclerotiorum decreased the severity of white mold of bean.
- Intervention effect Extracts of the E. purpurascens culture filtrates inhibited ascospore germination and mycelial growth of S. sclerotiorum.
- Intervention effect Hyphal growth of S. sclerotiorum was similarly inhibited when dual cultured with E. purpurascens.
- Observation Contact and penetration of S. sclerotiorum hyphae by E. purpurascens hyphae occurred rarely on agar-covered slides and was not observed on flower petals.
- Intervention effect Ascospore germination and germ-tube elongation of S. sclerotiorum were inhibited on agar-covered slides where E. purpurascens had been grown previously.
- Intervention effect Addition of nutrients decreased the inhibition of S. sclerotiorum ascospore germination and germ-tube elongation on slides previously colonized by E. purpurascens.
- Intervention effect Colonization of bean flowers by E. purpurascens reduced white mold incidence.
- Intervention effect The degree of white mold control by E. purpurascens flower colonization was affected by the addition of nutrients (direction not stated).
- Intervention effect The degree of white mold control by E. purpurascens flower colonization was affected by whether or not colonized flowers were autoclaved (direction not stated).
