When is Wilting Most Active Period on Chinese St John's wort?

Wilting is most active in warmer seasons when high temperatures promote the proliferation of pathogens and increase the plant's water usage, leading to stress and enhanced disease susceptibility.

Infectivity

Highly

Wilting disease, especially when caused by biotic factors, can easily spread from plant to plant, making it highly infectious.

Lethality

Moderately

While not all instances of wilting lead to plant death, when left untreated, the disease can be moderately lethal to Chinese St John's wort plants.
