Best Disease-Resistant Tomato Varieties for Common Tomato Diseases

When you’re growing tomatoes – probably the most popular plant for the backyard garden! There are all kinds of factors that you need to take into account.

How much water should you give them? What is the best way to fertilize? How do you prevent blossom end rot?

Tomatoes aren’t the hardest crop to grow, but they can be a little finicky. Many diseases can affect tomatoes, including alternaria blight, fusarium wilt and powdery mildew, to name just a few.

Fortunately, you can prevent most diseases by planting disease-resistant varieties. Here are some great options to consider when planning your garden next year.

most common tomato diseases

Although there are dozens — if not hundreds — of diseases potentially causing your tomato plants, some are more common than others.

1. Anthracnose

By far, it is one of the most common fungal diseases of tomatoes. This causes fruit rot, with small round spots that turn black in the middle. The disease is found in soil and is more common in wet climates and soils with poor drainage.

2. Early Blight

Early blight is the nemesis of most tomato gardeners. is caused by a fungus called alternaria solani, it can hang on for years as it winters in the soil. It does not usually kill tomato plants completely, but can seriously inhibit their growth as it can almost completely defoliate the plant.

3. Late Blight

Late blight is another frustrating disease but the good news is that it’s not common to northern gardeners—it usually isn’t able to survive cold temperatures. A fungal infection, this water-soaked spot causes the entire plant as well as many other unpleasant symptoms.

4. Fusarium Wilt

Fusarium wilt is more common in warm, southern growing regions, causing symptoms such as leaf drooping and plant death.

5. Mosaic Virus

Mosaic virus can get behind all kinds of plants, including tomatoes and even tobacco. This will not kill your plant completely but will lead to low or poor quality yield.

6. Septoria Leaf Spot

Yet another fungal disease to watch out for is Septoria leaf spot. Due to this, dark brown spots appear on the leaves of tomato.

This list is certainly not exhaustive – you can learn more about common tomato diseases here. In addition to these potential diseases, several nutrient deficiencies are often misdiagnosed as diseases (blossom and rot are just one example).

Best disease resistant tomato varieties

When it comes to preventing diseases on your tomato plants, there are dozens of options for you to choose from. Finding the right tomatoes depends on what type of tomato you want to grow (sauce, cherry, slicing, etc.) and what diseases you want to avoid.

Here are some good choices for disease-resistant tomato varieties.

1. ‘Early Girl’ – Fusarium Wilt

Plus, you won’t have to worry about early blight—another benefit to growing this cutie.

7. ‘Better Boy’ – Anthracnose

Anthracnose isn’t the only disease to which ‘better boy’ is resistant – but it is one of the most devastating. Therefore, developing a ‘better guy’ is a smart choice.

It’s also smart for other reasons. The plant produces a large number of fruits, many of which are a pound or more in size. Your harvest will begin in mid-season and continue until the first frost. It also has good foliage cover, which can prevent sunbathing in hot weather.

8. ‘Margold’ – Tomato Leaf Mold

‘Margold’ is another tomato variety with fun colors and excellent disease resistance. It’s the gorgeous look and flavor of the classic red-striped yellow heirloom tomato, offering exceptional disease resistance and excellent yields.

Not sure which varieties to go with? Check the seed packet or plant label to find out what diseases your chosen variety is resistant to. If you haven’t had problems with diseases in the past, you can probably get away with planting anything you want. However, if you are battling a specific disease, check the label to make sure the variety you choose has some resistance.

Other ways to prevent tomato disease

If you’re reading this article and have already sown seeds for the year, don’t panic. Not all hope is lost when it comes to preventing tomato diseases.

Fortunately, there are many more ways to keep your plants healthy than planting resistant varieties. One is to mulch your plants. This will help prevent soil-dwelling fungal spores from getting on your plants. It can also help control soil moisture and suppress weeds, two of the biggest culprits when it comes to spreading disease.

Speaking of watering, practicing good watering techniques is another way to limit the chance of diseases. Water only at the base of your plant to help keep foliage dry. Although using sprinklers can be a serious time saver, splashing water and soil all over your plant will increase the chances of disease.

Finally, if you suspect disease in your tomato plants, go ahead and prune. Remove at least the lower leaves and branches to prevent them from touching the soil. This way, you will be able to reduce the chances of soil-dwelling bacteria and fungi getting on your plants.

At the end of the growing season, be sure to clear all debris from your garden. This will reduce the chances of any nasty diseases from overwintering in the soil.

Next year, be proactive in your approach to disease prevention!

Rotate your crops—don’t plant your tomatoes in the same spot every year—and grow some of these top disease-resistant tomato varieties. There really is something here for everyone!
