If you see any of these diseases on your cabbage plants, it is important to take action to control them. You can use a fungicide or pesticide to treat the disease, or you can remove the affected leaves and destroy them.

It is also important to practice good cultural practices to prevent diseases from occurring in the first place. These practices include:

• Planting cabbage in well-drained soil
• Rotating crops
• Avoiding overhead watering
• Controlling pests and weeds
• Planting resistant varieties
