Other claims from this paper (6)
- Observation Leaf blight was observed on cosmos leaves in Nonsan, Korea.
- Observation Morphology distinguished the isolate from Alternaria zinniae by a branched beak.
- Observation Combined Alt a1 and gpd sequences did not distinguish the isolate from A. passiflorae.
- Observation A. passiflorae differed by conidiophores bearing four to five conidiogenous loci.
- Intervention effect The isolate caused disease on Cosmos bipinnatus leaves in pathogenicity tests.
- Observation The study reports the first Korean occurrence of A. cosmosa leaf blight on cosmos.
