Control

You should destroy plants after harvest to prevent the spread of bacterial spot. Good sanitation helps; keep weeds under control and remove plant debris. Rotate crops so that you are not planting solanaceous crops (tomato, pepper, tomato, potato) in the same area season after season, and if you buy seedlings, be sure that they are disease free before transplanting.
