Other claims from this paper (7)
- Observation Petiole lesions and inflorescence necrosis were caused by the fungus.
- Observation The fungus was found on some seeds.
- Observation Seed infection was generally superficial but sometimes deeper.
- Intervention effect Thiram soaking eliminated seed infection.
- Observation Heavily infected seed produced a low proportion of seedlings with cotyledon lesions.
- Observation Hypocotyl lesions also occurred, though their fungal cause was uncertain.
- Observation The outdoor test found no evidence that infected seed ultimately produced roots with Itersonilia cankers.
