Once a plant is infected with bacterial wilt, there is no cure. If you have soil that is contaminated with bacterial wilt, you need to either make sure not to plant anything from the nightshade family (e.g. eggplant, tomatoes, potatoes) for at least 2 years or you can solarize the location. Here are directions for solarizing: https://www.gardeningknowhow.com/garden-how-to/projects/how-to-solarize-garden-beds-to-eliminate-garden-pests-in-the-soil.htm
If it is a fungal issue, you can usually treat the plant with neem oil. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
