- Observation Watermelon isolates grouped to five Alternaria species and one unclassified Alternaria species.
- Observation Watermelon leaf blight isolates included A. tenuissima, A. alternata and A. cucumerina.
- Observation A. tenuissima was the most prevalent Alternaria species among the watermelon isolates, at 73.5%.
- Observation A. alternata was prevalent among the watermelon isolates, at 25.0%.
- Observation A. cucumerina was prevalent among the watermelon isolates, at 1.1%.
- Observation Alternaria sp. was prevalent among the watermelon isolates, at 0.2%.
- Observation A. infectoria was prevalent among the watermelon isolates, at 0.1%.
- Observation A. gaisen was prevalent among the watermelon isolates, at 0.1%.
- Intervention effect A. cucumerina caused significantly higher watermelon leaf disease incidence (75.1%) than A. alternata.
- Intervention effect A. alternata caused lower watermelon leaf disease incidence (52.9%) than A. cucumerina.
- Intervention effect A. tenuissima caused lower watermelon leaf disease incidence (47.5%) than A. cucumerina.
- Intervention effect Inoculation with Alternaria sp. caused lower watermelon leaf disease incidence (70.0%) than A. cucumerina.
- Observation Watermelon leaves inoculated with A. infectoria developed 28.9% disease incidence.
- Observation Watermelon leaves inoculated with A. gaisen developed 48.9% disease incidence.
- Observation All six Alternaria species produced brown necrotic lesions on detached watermelon leaves.
- Observation A. infectoria, A. gaisen and an unclassified Alternaria species are first reported causal agents of leaf blight on watermelon.
- Observation Alternaria species causing watermelon leaf blight in China are more diverse than previously reported.
