Mild (left) and severe (right) vascular discoloration of pepper. Bacterial wilt in carnations is caused by Pseudomonas caryophylli in a synergistic relationship with Corynebacterium. The lower stems of affected plants develop dark, vascular browning that often extends into the cortical and pith tissues… Therefore, bacterial wilt infection can be controlled by the use of the resistant cultivars identified in this study. Bacterial spot was first observed on tomato in South Africa as early as 1914. Defoliation or prolonged wilting caused by other diseases, such as Verticillium wilt, root-knot nematode, and bacterial leaf spot, or by salt and wind injury, can contribute to problems of sunburn. Commercial pepper and eggplant varieties with intermediate resistance to Bacterial Wilt are available. 2004). In tropical and subtropical regions, affected plants may wilt and die within days of infection. Since they belong to race 1, these biovars have a wide host range that guarantees long-term survival of the pathogen in soil in the absence of the main susceptible crop. Damping-Off and Root Rot.
