Leaves eventually yellow and brown at the margins, completely wither and die. Wilt progression varies by crop As the disease develops under favorable conditions, the entire plant may wilt quickly and desiccate, although dried leaves remain green, leading to general wilting and yellowing of foliage and eventually plant death. Another common symptom that can be associated with bacterial wilt in the field is the stunting of plants (Photo 2a and 2b)
