Bacterial wilt symptoms
Bacterial wilt symptoms

Bacterial Wilt is caused by the pathogen bacterium Ralstonia Solanacearum. Wilting first appears on the youngest leaves of plants during hot daytime temperatures. The infected plants may recover, temporarily, in the evening, when temperatures are cooler. A few days later, a sudden and permanent wilt occurs. The roots and lower portion of the stem have a browning of their vascular system. The invaded roots may rot due to infection from secondary bacteria.

Diseased stems that are cut and placed in a small container of water will show yellowish or grayish bacterial ooze coming from the cut end. When conditions are less favorable for disease development (for example, cool and dry), the infected plants may only show signs of stunting, and adventitious roots may develop on the main stems. The lower leaves will turn yellow before wilting symptoms occur.
