Bacterial Soft Rot of Pepper
Pectobacterium carotovorum subsp. carotovorumbacteria
Initial symptoms often become visible as dark vein tissue and necrotic areas on leaves. Sunken, water-soaked lesions appear and expand rapidly on stems, fruits, and fruit peduncles. As the disease progresses, dry, dark brown or black stem cankers might develop, often resulting in the breakage of branches. Finally, the entire fruit has become a watery, soft, slimy mass. It hangs from the plant like a water-filled bag. In general, bacterial ooze can be seen in diseased tissues and a foul odor can be present. The affected plants wilt and die later.
The soil-borne bacteria that cause soft rot are ubiquitous in the environment. They are associated with surface water and the soil. Warm and moist weather is highly favorable for infection. The bacteria enter the plant through wounds produced during the handling of the cultures, insect stings and sunscald. Pectobacterium carotovorum subsp. carotovorum have a lot of host plants, for example potato, sweet potato, cassava, onion, cabbage, carrot, tomato, bean, corn, cotton, coffee and banana.

Always consider an integrated approach with preventive measures together with biological treatments if available. A chemical treatment of the seeds and harvested fruits with a sodium hypochlorite solution can be useful to prevent further contamination. For example, seeds could be bathed in a 1% sodium hypochlorite solution (bleach) for 30 seconds and rinsed afterwards with clean water.
