How do you cure basil diseases?

To cure basil diseases, start by identifying the specific disease affecting the plant, such as downy mildew, fusarium wilt, or bacterial blight. Remove and dispose of any infected leaves or plants to prevent spread, and ensure proper air circulation and sunlight by spacing plants correctly. Apply organic fungicides or bactericides as needed, and practice crop rotation and good sanitation to minimize future outbreaks. Additionally, maintaining healthy soil and providing adequate watering can help strengthen the plants against diseases.
