Introduction
Growing tomatoes can be a rewarding experience, but it’s important to be aware of the common diseases that can affect your plants. By understanding these diseases and taking steps to prevent and treat them, you can keep your tomato plants healthy and productive.
Common Tomato Diseases
There are many different diseases that can affect tomato plants, but some of the most common include:
- Tomato blight: This is a fungal disease that causes brown or black spots on the leaves, stems, and fruit of tomato plants. It can spread quickly in warm, humid weather.
- Fusarium wilt: This is a fungal disease that causes the leaves of tomato plants to turn yellow and wilt. It can eventually lead to the death of the plant.
- Verticillium wilt: This is a fungal disease that causes the leaves of tomato plants to turn yellow and wilt, similar to Fusarium wilt. However, Verticillium wilt affects both sides of the plant at once.
- Anthracnose: This is a fungal disease that causes small, circular, sunken spots on the skin of tomato fruits. It can make the fruit inedible.
- Molds & mildews: These are fungal diseases that cause a white or gray powdery substance to appear on the leaves of tomato plants. They can block sunlight and prevent the plant from photosynthesizing.
- Tomato leaf curl: This is a viral disease that causes the leaves of tomato plants to curl and deform. It can stunt the growth of the plant and reduce fruit production.
- Septoria leaf spot: This is a fungal disease that causes small, brown spots with yellow edges to appear on the leaves of tomato plants. It can weaken the plant and reduce fruit production.
- Bacterial speck: This is a bacterial disease that causes small, brown spots with an outer yellow ring to appear on the leaves and fruit of tomato plants. It can make the fruit unsightly but is not usually fatal to the plant.
Preventing Tomato Diseases
There are a number of things you can do to prevent tomato diseases, including:
- Planting resistant varieties: Choose tomato varieties that are resistant to the diseases that are common in your area.
- Spacing plants properly: Space tomato plants far enough apart to allow for good air circulation. This will help to prevent the spread of fungal diseases.
- Watering at the base of the plant: Avoid watering the leaves of tomato plants, as this can create a moist environment that is conducive to disease.
- Removing diseased plants: If you notice any diseased plants, remove them from the garden immediately to prevent the disease from spreading.
- Cleaning your tools: Always clean your gardening tools before and after using them to prevent the spread of disease.
Treating Tomato Diseases

- Using fungicides: There are a number of fungicides available that can be used to treat tomato diseases. Be sure to follow the directions on the label carefully.
- Using homemade remedies: There are also a number of homemade remedies that can be used to treat tomato diseases. Some common remedies include baking soda, dishwashing soap, and cooking oils.
- Removing infected leaves: If the disease is only affecting a few leaves, you can remove them to prevent the disease from spreading.
