Other claims from this paper (8)
- Observation Powdery mildew was repeatedly found in Busan since 2009.
- Observation Disease symptoms formed white patches and hyphal growth on leaves and stems.
- Association High disease severity impaired growth, caused early senescence, and reduced flowering.
- Observation Morphology was consistent with P. xanthii.
- Observation ITS sequence matched Podosphaera sequences from other Verbena hosts at 100%.
- Intervention effect Inoculated plants developed symptoms after six days while controls did not.
- Observation The inoculated fungus matched the fungus initially observed.
- Recommendation Authors suggest mildew could limit host expansion in Korea.
