Bacterial Wilt is a plant disease caused by the bacterium Ralstonia solanacearum. It primarily affects crops like tomatoes, potatoes, and eggplants, leading to wilting and yellowing of leaves. The bacteria enter the plant through the roots and multiply, blocking water flow and causing the plant to wilt. Infected plants often show symptoms such as stunted growth and dark, water-soaked areas on stems. The disease can spread through contaminated soil, water, or tools, making it important for farmers to practice good hygiene and crop rotation to manage and prevent outbreaks.
