Other claims from this paper (8)
- Observation Ten-year-old Pinus taeda in Santa Catarina plantations showed decline symptoms.
- Observation Declining trees showed needle chlorosis, drying, shortening, branch-tip tufts and canopy death.
- Observation Declining trees had reduced secondary-root volume, absent ectomycorrhizae and external necrotic lesions.
- Observation 2 isolates from declining pine were identified as Ilyonectria leucospermi.
- Observation 2 isolates from declining pine were identified as I. robusta.
- Observation 1 isolates from declining pine were identified as I. vredenhoekensis.
- Observation Koch’s postulates confirmed pathogenicity of the isolates on P. taeda seedlings.
- Observation The identified pathogens were reported to cause disease in P. taeda and be associated with decline in Brazil.
