Other claims from this paper (18)
- Observation The rust has caused little damage to native Florida Myrtaceae over 30 years.
- Observation The rust host range in Florida grew to about 30 mostly nonnative Myrtaceae species.
- Observation Florida native Myrtaceae are largely resistant to P. psidii.
- Observation Non-neotropical Myrtaceae are expected to be more vulnerable to P. psidii.
- Observation Rust strains differ in their ability to infect host plant suites.
- Observation Five of eight native Myrtaceae and at least 15 nonnative species have been observed as rust hosts in Hawaii.
- Observation Eugenia koolauensis is severely damaged by the rust.
- Observation Eugenia reinwardtiana is severely damaged by the rust.
- Observation Syzygium jambos shows widespread crown dieback.
- Observation Syzygium jambos has many instances of complete tree death.
- Observation Rust occurs on less than 5 percent of wild ohia trees within its elevation range.
- Observation On infected ohia trees, rust normally occurs on less than 5 percent of leaves.
- Observation The Hawaiian rust strain has not attacked common guava.
- Method / resource Visual inspection has limited ability to detect rust because of capacity and latent infection.
- Method / resource Molecular tests could improve detection efficiency, but cost and time preclude routine port use.
- Recommendation Interdiction is presented as the strongest protection for Hawaiian native ecosystems from P. psidii.
- Recommendation Excluding new P. psidii strains may support long-term nioi survival and ohia forest health.
- Recommendation The authors call for investigation of rust–nioi relationships.
