e0“The majority of P. cactorum isolates causing crown rot symptoms were taken from infected strawberry crowns, although two isolates from gooseberry plants, but of uncertain origin, were also pathogenic.”

Other claims from this paper (9)
- Intervention effect Cold-stored strawberry cultivars were more susceptible to pathogenic P. cactorum isolates than plants without cold storage.
- Observation Indigenous nonpathogenic P. cactorum isolates did not cause crown rot in cold-stored strawberries.
- Observation A small number of symptomless latent infections occurred with indigenous nonpathogenic isolates.
- Observation Most isolates causing crown rot symptoms came from infected strawberry crowns.
- Association Symptomless infections initiated before cold storage led to a high incidence of death in storage and chronic wilt after planting.
- Association Infection immediately after cold storage led to rapid wilt symptoms of Phytophthora crown rot.
- Observation Infected tissue from plants that died in cold storage produced many sporangia and zoospores after plating in water for 24 h.
- Mechanism The authors infer that importing non-indigenous inoculum with planting material likely causes crown rot outbreaks in previously unaffected areas.
- Mechanism The authors propose that cold-induced susceptibility together with latent infection or debris may trigger sudden large crown rot outbreaks.
