Quick Intro
Physical Description
Fungal wilt disease that often starts on one side of a plant, then works its way up. On individual leaflets, you can see it go down one side, then come back on the other side. If you live in a hot area, Verticillium stops causing problems once the temperatures climb and humidity decreases.
