4. In early stages of wilting leaves remain green, but later yellowing and brown necrosis develops.
5. When wilting does occur, the symptoms are as described for tomato.
6. Observe for symptoms of wilting and/or epinasty, chlorosis and stunting.
7. With pure cultures typical wilting should be obtained within 14 days.
