The following table gives a summary version of the information above. Note:

• For “DR” (disease resistance), E means early blight resistant, L means late blight resistant, and EL means resistant to both types of blight.
• For “Habit”, D means determinate (not as tall) and I means indeterminate (tall).
• The “WT” (fruit weight) is in ounces.
• DTM stands for days to maturity (the time it takes from transplant to mature fruit harvest).

Type	DR	Habit	WT	DTM
Mountain Magic	E&L	I	2-3	70- 80
Plum Regal	E&L	D	4	75
Defiant PhR	E&L	D	6-8	67

Legend	L	D	8	68
Verona	E	I	2. 5	69
Valentine	E	I	<1	55

This table summarizes information on 10 types
of blight resistant hybrid tomato varieties.

As you can see, many of these blight resistant tomato varieties are small, weighing 2 ounces or less. However, there are some varieties with medium fruit size (4 to 5 ounces or more).

If you like to experiment by crossing plants, you can also look into grafting tomato plants to provide them with more disease resistance.

How To Prevent Tomato Blight

Now that we have a list of blight-resistant tomato varieties to choose from, let’s review some other steps you can take to avoid these dreadful tomato diseases.

First, it is important to keep in mind the two types of blight that can affect tomatoes: early blight and late blight (both caused by different types of fungus).

Early blight (caused by one of the two fungi Alternaria tomatophila or Alternaria solani) can weaken tomato plants and affect your harvest.  It spreads more rapidly in damp, humid conditions.

Here we can see signs of early blight on tomato leaves.

Late blight (caused by the fungus Phytophthora infestans) can kill a tomato plant within a few days of infection.  Left unchecked, a late blight outbreak can destroy your entire tomato crop.  It spreads more rapidly in cool, wet conditions.

Here we can see signs of late blight on a tomato stem. Late blight is the more deadly of the two blights for tomato plants.

Even worse, early and late blight can also affect potatoes, posing a threat to your potato crop as well.  In fact, late blight was responsible for the Irish Potato Famine in the 1840’s.

Here we see a potato affected by late blight.

For more information on blight resistant tomatoes, check out this article from the Cooperative Extension (eorganic.org) on late blight management.

You can also check out this article on early blight from the University of Minnesota Extension.

If you want more information on how tomato plants get blight in the first place, check out my article on how tomato plants get blight.

Now let’s get to the ways you can prevent blight in the first place, whether you plant blight-resistant tomato varieties or not.

Leave Enough Space Between Your Tomato Plants

If you put your tomato plants too close together, their leaves will touch as their branches grow longer.  This makes it easier for early and late blight to spread between plants – possibly making their way up an entire row!

Putting plants too close together also increases the chance that splashing water (from rain or irrigation) will cover the leaves of multiple plants with infected soil.

If you put your tomato plants too close together, the spread of diseases such as blight is more likely.

Fortunately, there is an easy way to prevent these problems.

When ordering tomato seeds or seedlings, check the width (spread) of the variety you choose. If the catalog doesn’t list the information, call or email to ask about it.

For example, Burpee lists the spread for Mountain Magic tomatoes at 48 to 52 inches (over 4 feet). However, you might want to leave a little more space between each plant than the width indicates.

For example, if the catalog lists a tomato variety as having a width of 48 to 52 inches, you might want to leave 55 to 60 inches between plants, just to be safe.

Leave at least as much space between rows of tomato plants. This will give you room to water, fertilize, harvest, pull weeds, and prune your tomato leaves and vines during the season.

Use Crop Rotation In Your Garden

Early blight can survive in the soil on its own over the winter, which makes it the more difficult disease to eradicate.

On the other hand, late blight cannot survive in the soil on its own over the winter. However, it can survive inside of infected plant matter (such as potato tubers).

This means that you should use crop rotation in your garden to prevent the spread of blight.  Crop rotation means you do not plant the same crop type in the same part of your garden two years in a row.

Be sure to practice crop rotation to prevent the spread of blight. Do not plant tomatoes in the same spot in your garden two years in a row!

In fact, the ideal crop rotation schedule has a 3 or 4 year rotation cycle.  For example, in a given area:

• Plant tomatoes in year 1
• Plant onions in year 2
• Plant beans in year 3
• Plant lettuce in year 4

Rotate tomatoes with other crops in your garden to avoid the spread of disease from year to year.

After that, start back at the beginning and begin the rotation again.   This allows more time for any plant diseases (such as blight) to die off from the soil.

You can learn more about good crops to rotate with tomatoes in my article here.

As mentioned earlier, early and late blight can affect both tomatoes and potatoes (both are in the nightshade family). So, these two crops should not be planted near each other.

They also should not be planted in the same area two years in a row (that is, do not plant tomatoes in an area the first year and then potatoes in the same area the 2^nd year). Otherwise, tomato blight may soon manifest as potato blight, or vice versa.

Support Your Tomato Plants

When tomato plants touch each other, blight and other diseases spread more easily.  Your plants are likely to touch if they grow along the ground, as unsupported tomatoes will do.

Growing tomato plants along the ground also means that the stems and leaves are in contact with wet soil.  This increases the chances of disease spreading in your garden.

To prevent this, support your tomato plants with trellises, stakes, or tomato cages.

For determinate tomato varieties (which tend to be shorter), cages are a good choice. (Cages can also be used for pepper plants to provide support.)

For indeterminate tomato varieties (which tend to be taller), a stake or trellis is the better choice.

For shorter, determinate tomato varieties, a tomato cage is a good choice for support.

Supporting your tomato plants will help to prevent disease. It also saves you from having to bend over to harvest tomatoes from the ground.

For indeterminate tomato varieties, stakes (shown here) or trellises are a better choice for support.

For more information, check out my article on tomato cages, my article on trellises, and my article on supporting tomatoes.

Remember that if you choose stakes, you will need to tie the tomato plants somehow. You can learn more about what to use for tying tomatoes in my article here.

Inspect Your Tomato Plants For Disease

Don’t leave anything to chance!  Even if you choose blight-resistant tomato varieties and take the other steps on this list, you should still check your tomato plants for disease.

If you see plants with signs of blight, remove them from the garden to prevent the spread of the disease.

The sooner you find tomato plants infected with blight, the sooner you can pull them out, destroy them, and prevent the spread of the disease.

Some folks recommend composting infected plants, but I recommend against it.  The main reason is that the compost pile may not get hot enough to kill diseases – and many diseases can survive the winter in a compost pile.

Prune The Lower Leaves & Branches Of Your Tomato Plants

The lower leaves and branches of your tomato plants are more likely to get wet due to splashing from rain or watering.  They are also more likely to stay wet, since less sunlight will reach them to dry them off.

The lower leaves and branches are also more likely to hang down and touch the soil, where they can pick up diseases.

Pruning the lower leaves and branches of your tomato plants prevents the spread of blight.

To prevent this problem, your best bet is to prune off low-hanging leaves and branches from your tomato plants as they grow.   At first, it might seem silly to do this to a healthy branch or leaf.

However, if it prevents the spread of blight, then it is worthwhile to save your plant (or your entire tomato harvest!)

While you’re at it, you can also “top” tomato plants by pruning off the tops of tall indeterminate varieties. This will keep them from falling over due to excessive height or weight.

For more information, check out my article on tall tomato plants and how to prune them.

Water Your Tomato Plants From Below

Watering tomato plants from below will keep the upper and lower leaves from getting wet.  Keeping the leaves dry is an important step in preventing the spread of both early and late blight (both thrive in damp conditions).

Water your plants carefully from below, using a hose or watering can, to prevent the leaves from getting wet.

Instead of using a sprinkler, use a garden hose or a watering can to control the amount and location of the water you give your plants.

You can also install a drip irrigation system. This will water at the soil level so that the leaves will never get wet.

You can also set up a drip irrigation system to run on a timer. This will help you to avoid over watering.

Sanitize Your Garden Tools

Since early blight can survive in soil on its own over the winter, it is a good idea to sanitize garden tools after using them.

For example, have a bucket of soapy water or a rag with alcohol to clean off pruning shears after you finish pruning each plant.

Sanitize your garden tools after use – alcohol or soapy water will help to get rid of diseases.

Otherwise, if the first plant has blight, you can potentially infect every other tomato plant in your garden!

Conclusion

Now you have a solid list of 10 blight-resistant tomato varieties to choose from.  You also have some actionable advice about how to avoid early blight and late blight in the first place.

Bacterial wilt of tomatoes is often mistaken for blight. You can learn more about bacterial wilt of tomato in my article here.

Blight-Resistant Tomato Varieties Worth Growing

17 January 2014, written by Barbara Pleasant

Even though our gardens are more than three thousand miles apart, GrowVeg founder Jeremy Dore and I experienced similar tomato miracles in our gardens last year: the plants did not die. Eventually they did, of course, but with the help of special genes, the plants did not melt down with late blight following periods of rainy weather. We both grew blight-resistant tomato varieties for the first time, and now we can't wait to try more of these naturally healthy tomatoes.

First let's clarify what we mean by "blight." Tomatoes in a wide range of climates are bothered by early blight (Alternaria solani), a fungal disease that causes dark spots to form on the lowest leaves. Early blight needs damp leaf surfaces to prosper, so the shaded leaves low down on the plant, which dry slowly, wither from early blight while lovely new growth continues higher up, where sunshine and wind keep the leaves comparatively dry. Evidence of this extremely common disease are plants with withered foliage to about 18 inches (46 cm) from the ground, with healthy green growth higher up. Early blight weakens tomato plants but does not kill them.

Late blight does kill tomato plants, and once the killing starts there is no stopping it. Caused by a fungus-like oospore, late blight (Phytophthera infestans) also devastates potatoes. Unlike early blight, late blight on tomatoes develops later in the summer, and always following a period of prolonged rain. Moisture and plenty of it is required to bring late blight to life, but problems have become much more widespread in recent years, especially in the north and eastern US, where late blight of tomato has gone from being an occasional problem to a constant concern.

Enter new varieties imbued with two or more genes that give them excellent resistance to late blight, and some resistance to early blight, too. And not to worry, these genes were manipulated using traditional breeding techniques, mostly under the direction of Dr. Randy Gardner, Professor Emeritus at North Carolina State University, who has been breeding better tomatoes for more than 30 years. Gardner and his team began making progress with blight resistance in the late 1980s, but their great gift to the gardening world came in 2010, when they released an ensemble of breeding lines with multigenic resistance to both blights to anyone who wanted to work with them.

The variety I grew, 'Mountain Magic', came directly from Gardner's program, but several more blight- resistant tomato varieties show the finishing touches of other breeders – including home gardeners who work with heirlooms. In 2012, when researchers in New York evaluated late blight tolerance in 35 tomato varieties, the winners were an interesting mix of hybrids ('Defiant', 'Plum Regal', 'Mountain Magic 'and 'Mountain Merit') and heirlooms 'Lemon Drop', 'Matt's Wild Cherry', and 'Mr. Stripey' (also called Tigerella). More recently, super-resistant 'Iron Lady' was added to the list, along with 'Jasper', a tasty red cherry. See the alphabetized list below of these blight-resistant tomato varieties.

The Troubled Trans-Atlantic Crossing

While US gardeners have plenty of choices among disease-resistant tomatoes, the only up-to-date variety available in the UK appears to be 'Jasper', which has earned an RHS Award of Merit. The variety Jeremy grew with such excellent results was 'Fantasio', which likely has single-gene resistance to late blight. An older hybrid, 'Ferline', fits into the same category; it will hold up under light disease pressure but will succumb when things get really bad. US-bred 'Legend' is also recommended to UK gardeners for its disease resistance, but it never emerged as a winner in the US, probably due to its single-gene resistance.

Until European seed companies start selling the vastly improved new American varieties, the most economical option for gardeners in the UK and other countries who want to try them is to have a friend buy seeds in the US (from Jung or Johnny's, for example), and send them on. If you were traveling from outside the EU, you would be allowed to bring back up to five packets of commercially-packaged seeds, and the same import policy appears to apply to mailed seeds. One US seed company, Tomato Growers Supply Company, will ship international orders for a flat special handling fee of $12 USD.

Phytophthora resistant tomatoes - for greenhouses, open ground, 20 varieties not suffering from late blight

Tomato late blight is one of the most common and dangerous enemies of the nightshade crop. The appearance of small spots on the leaves and fruits provokes their irreversible death. Treatment or prevention of the disease requires great effort, and the result cannot guarantee the restoration of plants. To preserve the crop, it is easier to plant tomatoes in open ground, which are not afraid of phytophthora. Modern breeding offers a large number of varieties resistant to fungal infection. nine0009 Kuma

Evpator F1

Mona Lisa

Overture NK

Cardinal

Tomatoes up to 1 m high are considered to be undersized. Bushes are good both for planting in open ground and for growing in greenhouses or greenhouses. The following low-growing varieties are labeled by manufacturers as resistant to phytophthora.

Lark F1

Determinate hybrid tomato Lark is characterized by the following qualities:

• strong stems up to 100 cm high;
• rounded, slightly flattened fruit shape;
• mass of tomato about 115 g;
• firm red tomato skin resistant to cracking.

Lark F1 matures 80-85 days after planting. This is what gives plants the opportunity to avoid infection with late blight, which is activated in the second half of summer. In addition, first-generation hybrids are distinguished by good health and endurance. nine0003

Dubrava

The variety Dubrava is determinant, bushes grow up to 60 cm. Tomatoes ripen early, no later than 93 days from sowing seeds.

Tomatoes of this species are distinguished by:

• yield up to 2 kg per plant;
• round, ribbed red fruits, weighing up to 0. 1 kg;
• versatility of application;
• cultivation without pinching, tying.

When planting seedlings according to the scheme up to 6 plants per square meter, the tomato maintains resistance to late blight at an average level. Bushes can be formed into 3-4 main stems, since the lower shoots are quite high, and the leaves are small. nine0003

Blitz F1

Hybrid Blitz F1 equally suitable for greenhouse and outdoor planting. Ultra-early fruit ripening protects the bushes from rains in the second half of summer, which provoke the appearance of phytophthora. In addition, tomatoes are resistant to tobacco mosaic and Fusarium.

For protection, bushes are recommended to be planted according to the scheme 40x50 cm. Plants are formed in 2-3 main shoots without pinching.

Fruit characteristic:

• round form;
• red at maturity;
• yield about 3.3 kg per bush;
• weight approx. 85 g;
• universal crop use.

Alpatyeva 905 A

• short growing season up to 95 days;
• moderate foliage;
• formation of fruits in clusters of 4-6 pieces;
• ripening up to 14 kg of tomatoes per bush;
• mass of tomato from 60 to 80 g;
• fruit round or slightly flattened, slightly ribbed;
• rich taste;
• few seeds in chambers.

The variety tolerates cold weather well, and also rarely gets sick with late blight or other infections. nine0003

Ogni Moskvy

The tomato variety Ogni Moskvy was selected about 20 years ago for planting in unprotected ground. Low determinant plants are suitable for growing in vegetable gardens or farms.

Characteristics of tomatoes:

• plant growth time 95-105 days;
• semi-spreading shrub;
• plant height 45 cm;
• absence of stepsons;
• strong stems that do not require support;
• drought tolerance; nine0012
• yield is about 5 kg per square meter of plantings.

Lights of Moscow tomatoes ripen in bunches of 6-7 pieces. In the period of ripeness, rounded tomatoes turn red and gain weight of 100-110 g.

The species is resistant to lack of moisture, fruit cracking and fungal diseases, including late blight.

Shuttle

Tomato variety Shuttle was selected in 1993 mainly for use in whole-fruit canning. Shtambovy bushes grow about 45 cm in any type of soil. Thick short stems with low density shoots and small leaves have an average resistance to phytophthora infection. nine0003

The fruits of Shuttle are characterized by:

• formation in racemes of a simple type, 6-7 tomatoes each;
• oblong oval shape;
• pointed tip;
• weight up to 55 g;
• smooth, dense scarlet skin;
• firm flesh with few seeds;
• delicate aroma, bright tomato taste.

In addition to phytophthora, the variety tolerates cool weather and rains well. Regardless of external factors, the fruits stay on the branches, do not overripe and do not crack. nine0003

Buyan

Buyan tomatoes stop growing at half a meter. Seedlings take root well in greenhouses and open beds. Plants have strong stems, weak stepchildren and medium-sized leaves.

The fruits resemble red cream, up to 70 g in size, collected in a brush. Tomatoes have small seeds, firm flesh and good taste.

The yield reaches 2.5 kg per bush, and the tomatoes are used for canning and salads. nine0003

The variety is immune to bacterial infections, viral tobacco mosaic and late blight.

Budenovka

Tomato Budenovka was registered in the State Register about 15 years ago. The variety is best suited for salads and raw appetizers.

Cultivar belongs to the determinant type. The growing season lasts at least 110 days.

When growing bushes, it is enough to leave 2-3 stems as the main ones, and also regularly remove stepchildren. nine0003

Large fruits reach a weight of 0.3 kg. The sugary taste of red pulp and dense skin are the main advantages of Budenovka. The variety is resistant to late blight, powdery mildew, and other infections.

Medium and tall

Tomato varieties resistant to late blight for greenhouses, most often of medium or high growth. Such tomatoes grow above the 100 cm mark, require mandatory tying and shaping during the growing season.

Sweet Bunch

Sweet Bunch Tomatoes differ in color as there are yellow, red and chocolate varieties. nine0003

The variety is intended for planting in a greenhouse; in unprotected soil, the tomato yield decreases.

Vegetation of plants lasts 100 days, during which time without pruning the bush can grow up to 2.5 m. Up to 20 round tomatoes, weighing 20 g each, are formed in each brush. nine0003

Black Prince

Tall shrub belongs to the mid-season species, as Black Prince tomatoes ripen after about 120 days. Plants are formed in 1-2 stems, stepchildren are removed, and the top is cut after flowering.

Large, brown-red fruit with good taste and versatility. The variety actively responds to watering and, with proper care, produces up to 3 kg of tomatoes.

The producer and gardeners note the high resistance of the tomato to late blight and other nightshade diseases. nine0003

De Barao black

This tomato is highly resistant to late blight. Late-ripening tomatoes ripen after 120-130 days from the start of growth.

Shrubs produce the most yield while retaining 1-2 main shoots. The fruits are small, weighing up to 60 g, collected in a brush.

The color of the skin when ripe is dark brown with a slight hint of purple. It is better to grow plants in a polycarbonate greenhouse, in the south - without shelter.

The variety does not get sick with late blight, and also withstands temperature fluctuations. nine0003

A bit about late blight

What is it? Tomatoes suffer from late blight as a result of infection with the late blight fungus. This rather stable organism tends to spread extremely quickly, infecting everything around. Phytophthora lives in the soil, plant debris and greenhouse construction. That is why the infection of tomatoes is extremely easy. Even if you have processed the greenhouse outside and inside, some of the pores of this fungus may remain in the cracks or they may be blown in by the wind when airing. nine0003

How does it manifest itself? First, a white coating (consisting of fungal spores) forms on the leaves, after which it turns into brown spots. Gradually, the trunk and branches of the plant are covered with such a raid, and, in the end, the infection passes to the fruits, making them completely unsuitable for food.

Conditions for development. The pores of the fungus are activated in the following conditions:
• High humidity,
• Dense planting or overgrowing with weeds,
• Excess nitrogen,
• Deficiency of potassium, magnesium or iodine.

Danger in the greenhouse. Many farmers believe that building a shelter for tomatoes will help protect them from late blight. But the truth is that the fence cannot be called a reliable shelter from late blight spores. In addition, the air inside the greenhouse is difficult to get rid of excessive moisture, so the spores that get there instantly multiply.

Late blight can destroy the entire crop in a greenhouse
