Quite a few
varieties of tomatoes that are resistant to late blight for greenhouses In our article, we tried to offer the best of them and gave them characteristics; we also provide a detailed description of late blight, methods of combating it, and consider the factors that provoke the disease,

Tomato plague, the most terrible disease of tomatoes - these are the names summer residents gave to late blight. This disease can lead to the death of nightshade crops. late blight throughout the entire period of tomato cultivation . For decades, vegetable growers have been inventing various methods to destroy the causative agent of tomato disease.

This has led to the emergence of various methods in the fight against late blight. There are conventional means, such as the use of drugs, and exotic ones, which include the use of copper wire for the roots of tomatoes, as well as sprinkling the plants with fresh milk.

Tomato varieties resistant to late blight for greenhouses

Today there are no types of tomatoes that are completely protected from late blight and are never affected by this disease. They are also affected by late blight, but tolerate it much more easily, since they are highly resistant to fungal infections.

How dangerous is late blight for tomatoes and what causes it?

Phytophthora is the name of a disease characteristic of the nightshade family, which is caused by a fungus.

Reference! The manifestation of the disease is watery spots covering the leaves of tomatoes. Then they begin to darken and soon become brown.

The spread of the fungus is observed on all parts of the plant; after the leaves, the stems and later the tomato fruits become infected. Late blight on a tomato is represented by a compaction under the skin of the fruit, darkening and increasing in size. As a result, the tomato is completely or almost completely deformed, its pulp becomes a brown substance with an unpleasant putrefactive odor.

Attention! Diagnosis of late blight in tomatoes is carried out by careful examination of the leaf, the underside of which, when infected, contains traces of a pale gray powdery coating. This plaque is formed by spores belonging to harmful fungi.

Important! Late blight is dangerous because its fungal spores are exceptionally resilient and spread very quickly. The death of a grower's entire crop can occur within just a few weeks. It happens that there is no way to overcome this disease.

A favorable environment for storing and propagating spores is formed in the soil. Late blight is not afraid of either extreme heat or low winter temperatures. It is extremely difficult to restore soil contaminated with spores that pose a threat to all crops belonging to the nightshade family.

Advice! It is very important to avoid planting tomatoes in a place where potatoes were previously grown.

Tomato beds should not be placed next to potatoes, as this vegetable can spread late blight very quickly.

Awakening of spores dormant in the soil occurs under the following conditions:

at low air temperatures in summer;
in case of insufficient illumination of the area, which is also facilitated by prolonged cloudy weather;
at high humidity, which is an excellent environment in which microorganisms multiply quickly;
with excessive watering;
with excessive fertilizing with nitrogen fertilizers;
with a lack of oxygen, poor aeration of plants;
with a lack of potassium, iodine and manganese in the soil;
when weeds grow among tomato bushes;

Advice! For the best results when fighting late blight, you should first of all eliminate the conditions that help the fungal disease develop.

Phytophthora-resistant varieties for open ground

When growing in open ground, it is best to use hybrids of domestic or foreign selection with strong immunity and high resistance to late blight and other fungal diseases.

Tomatoes resistant to late blight for open ground:

Pests, diseases and methods of controlling them

Pests

Tomatoes are distinguished by good health, however, they are also susceptible to a number of diseases and pest attacks.

The most common pests and methods of controlling them:

Slugs. To make them disappear, you should regularly loosen the soil near the stem and sprinkle with ground hot pepper (one teaspoon is enough per square meter of soil).
Whitefly is a small midge with light, almost transparent wings. Use Confidor or its analogues.
Spider mite. Barely visible to the naked eye, it resembles a small white dot. You can cure the bushes by spraying them with a soap solution, infusion of garlic and dandelion leaves, or treat them with Karbofos.
Aphid. Small light green insects. In some cases, you can simply wash off the adults with a strong stream of water from a hose. Insecticides must be used to control eggs and larvae.
Medvedka. A large (3-4 centimeters) insect that resembles a grasshopper without wings can be kept in the ground and eat roots. It has powerful burrowing legs and an elongated, full abdomen. To combat, gardeners use an infusion of hot pepper, a vinegar solution or chemicals, for example, “Thunder”.
Wireworm is a yellowish-brown larva of a click beetle, reaching two centimeters in length. It is useful to reduce soil acidity. Wireworms are removed by liming the soil and preparations such as Bazudin.
Gnawing cutworms are butterfly caterpillars. The color is gray, maybe almost black. The body does not exceed three to four centimeters in length. Pests are collected by hand, the beds are weeded, and the egg layings are poisoned with the drug “Strela.”

If proper agricultural practices are followed, the risk of pests and parasites is reduced significantly.

Diseases

Breeders have developed many varieties. Resistant to certain diseases, such as late blight or black rot. However, the risk of occurrence cannot be eliminated one hundred percent. Therefore, you should familiarize yourself with the main diseases of tomatoes in order to know what to deal with.

The most common ailments:

Late blight. Characteristic signs are brown and brown spots on all above-ground parts of the plant. It is necessary to treat with the drugs “Zaslon”, “Barrier” and “Oxyx”. Sometimes an infusion of garlic is used.
Blackleg. The stem at the base of the plant turns black and dries out, causing the plant to die. The disease cannot be treated; it often affects seedlings. To prevent the disease, use a solution of potassium permanganate (1-1.5 grams diluted in 10 liters of water).
Cracking. The reason is excessive watering after a drought. Therefore, it is very important to maintain a stable watering regime.
Dry spotting (Alternaria blight). At the beginning of development, the symptoms are very similar to late blight. Then dimples and indentations appear on the tomatoes, they have an oval shape on the stems, and round on the fruits. Infected and diseased bushes are sprayed with Antrakol, Consento, and Tattu.

Soil treatment and proper crop care are very important in disease prevention.

Medium and late varieties of late blight-resistant tomatoes

Tomato varieties with medium or late ripening periods can be short or tall, grown in open soil or in greenhouses. The only thing these varieties have in common is their high immunity to late blight and other fungal diseases.

Which tomatoes are not afraid of late blight?:

Selection of varieties for different climatic zones

The quality of the crop also depends on the growing region. The more fertile the soil and the warmer the climate, the higher the likelihood of getting a lot of tasty and ripe tomatoes. The tomatoes listed below are best grown in polycarbonate greenhouses, especially in central Russia.

Growing tomatoes in Siberia

The following tomatoes are best suited for Siberian lands:

Siberian early ripening;
Altai seeds;
Siberian Garden;
Demidov;
Ultra early ripening.

What tomatoes to grow in the Urals

Gardeners in the Urals should pay attention to the following varieties:

Raisin;
Skorokhod;
Lollipop;
Titanic;
Wonderful lady.

Choice for greenhouses in the Moscow region

Compared to the Urals and Siberia, the Moscow region has better climatic conditions for growing tomatoes. The following varieties are recognized as leaders:

Alenka;
Ox heart;
Nectar;
De Barao;
Mongolian dwarf.

Varieties that are not afraid of late blight for Belarus

Not all tomatoes with resistance to late blight grow well in Belarus due to the climate. However, there are several varieties that are suitable for this country:

Evgenia. Belarusian farmers prefer to grow Eugenia, since its bushes are rarely infected with fungal diseases. The variety is also distinguished by high-quality fruits that do not crack after picking and are suitable for pickling.
Aurora. Gardeners recommend planting Aurora if tomatoes are needed for preparing fresh salads. The taste of ripe tomatoes will make any vegetable dish much tastier. It is better to plant Aurora in greenhouses, where the temperature will remain above zero.
Admiral. Indeterminate tall plant with bushes 2-3 meters high. The Admiral's harvest is stored for a long time and can be transported over long distances without problems.

Reinsurance is the key to success

When preparing to sow seeds of any tomato variety, it is better to play it safe and adopt standard methods for sanitizing seeds. For this use:

Potassium permanganate.
Baktofit.
Bordeaux mixture.

Treating tomato seeds with a 1% potassium permanganate solution will protect tomato seeds from diseases. To do this, tomato seeds are wrapped in gauze and placed in a bowl with an already diluted purple preparation.

Experts recommend using the fungicide Baktofit when transplanting young seedlings into open ground. To do this, the drug is applied with watering at the root.

A 1% solution of Bordeaux mixture also fights putrefactive fungus well. After tomato ovaries appear on the bushes, they are sprayed with the preparation for 10–12 days until the berries are filled with red juice. Treatment is stopped 10 days before harvest.

Copper oxychloride solution copes well with the attacks of late blight. For 1 bucket they usually take 40 grams of the substance. After preparing the mixture, spray the tomato bushes with it. The procedure is stopped 20 days before picking ripe berries.

Proven ways to avoid getting infected

Proper watering will protect tomato beds from late blight. Water should be poured at the root of the plant, and not on its foliage and stem. To avoid the appearance of rot, a plastic bottle of water, with holes previously made in the walls, is buried next to the young seedling when planting. This way, the plant drinks without being exposed to excess moisture.

There are also old-fashioned methods of combating brown rot fungus. Tomato bushes used to be treated with cow's milk, iodine or mustard. Some experts are still confident that if you pierce a bush at the base with copper wire, then late blight is not dangerous. Few “old believers” still wrap the roots of young tomato seedlings with a coil of copper wire.

Every day scientists make new discoveries in various fields of science. Perhaps soon varieties of tomatoes that are completely resistant to all known diseases of these plants will appear on the shelves of garden stores.

Varieties for Ukraine

Ukrainian farmers, when growing tomatoes, often encounter a vegetable disease such as late blight. To prevent tomato bushes from getting sick, it is necessary to grow blight-resistant varieties that will grow well in Ukraine. These include:

Mobile Farmers from Ukraine often plant Mobile, as it bears fruit well in many areas of the country. If grown correctly, the yield will reach 10 kilograms per bush.
Pink cheeks. This is a heat-loving plant that is best grown in the southern regions of Ukraine. Ripe fruits weigh 300-350 grams.

Description and development process of late blight

Brown rot (late blight, late blight) affects all plants from the Solanaceae family, but tomatoes and potatoes are especially susceptible to infection.

The nature of the disease is fungal (scientists have identified more than 100 varieties of pathogenic microorganisms). Late blight is spread by spores. High humidity and air temperature, not higher than +22 degrees, contribute to widespread plant disease.

The sooner a gardener recognizes an infection, the easier it is to cure the plant. Late blight on tomatoes manifests itself as follows:

dark spots with a yellow edge appear on the underside of the leaf blade;
brown spots on the stems quickly become covered with a whitish coating;
on fruits, spots first appear near the stalk (this is the main difference between late blight and blossom end rot).

Bush with tomatoes in the garden

As the disease develops, the tomato greens turn yellow and dry out, the stem rots, and the fruits become soft. Sick plants serve as a source of infection for neighboring bushes.

Important! Fungal spores can easily be transferred on shoes, hands, and tools from diseased bushes to healthy ones. Infection can also occur through seed or soil.

Perseus tomatoes

Determinate early-ripening crop, the height of the bushes reaches 70 centimeters. The fruits ripen after 117 days. Their color is red, weight is about 130 grams. Transportation is well tolerated, and the original qualities are preserved.

Tomatoes Little Prince

An early ripening tomato variety that ripens 90-95 days after planting. Tomatoes, as the name suggests, are small, 40-45 g, round in shape. The fruits are considered universal and are great for eating raw and for canning. The variety is characterized by a stable harvest that ripens at the same time, and excellent taste.

Reviews from experienced farmers

What are the most productive tomatoes you should pay attention to? Among the positive properties, experienced farmers note the excellent taste of the Tatyana, Little Prince, and Cardinal varieties.

In addition, the varieties Volgogradsky, Babushkin Secret and Nagrada should be noted - many speak positively about these tomatoes, value them for their easy care and unique taste.

Reference. On online forums you can always read reviews from summer residents and gardeners - this is useful before you start planting this or that variety of tomatoes in your garden.

Peter from Magnitogorsk: “I’ve been planting the Cardinal variety on my plot for several years now, and I’m very pleased with the result. I am pleased that these tomatoes have excellent immunity to late blight.”

Anna: “We were dissatisfied with the Far North and Dubok varieties - these varieties have insufficient resistance to fungal diseases.”

Japanese creeping

A very miniature plant rarely grows above 30 cm. The shoots spread along the ground, so it is fundamentally important to adhere to the seating plan. A pleasant advantage is that the fruit-bearing bed also looks very nice.

20 Best Heat and Drought Tolerant Tomato Varieties

Reasons for the development of the disease

Tomato varieties resistant to late blight are being improved every year. Previously, they were represented only by early-ripening varieties, because a surge in the disease is observed in the second half of summer. During this period, heavy precipitation begins and frequent temperature changes. All this makes a favorable environment for the development of late blight fungus spores. The fungus does not tolerate sunlight, but in shady areas with high humidity it feels at ease and begins to develop quickly. The biggest problem is that the fungus can persist in the soil throughout the winter; it can withstand frost and begins to develop when the time is favorable.

Spores can remain not only in the soil, but also on seeds and unharvested plants. If it is possible to disinfect seeds and remove the remains of greenery, then it is impossible to get spores from the deep layers of the soil, so people began to select for planting low-growing varieties of early or medium ripeness that are not afraid of late blight. But there is one catch here: if early-ripening varieties are planted in order to get a harvest, and then sell it and sow new tomatoes, then the risk of late blight spreading to the second crop will be quite large.

Care

Selection does not stand still, and on the market today you can find many varieties that are practically not susceptible to fungal diseases. Still, it is worth selecting varieties depending on the climatic conditions of your region and following basic care rules.

For example, in the cool, important climate of the Moscow region, southern heat-loving plants should not be grown. If tomatoes are grown for sale, then in the climatic conditions of the Moscow region it is recommended to plant the vegetable in greenhouses: this makes it easier for the gardener to provide the necessary conditions and reduce the humidity in the greenhouse without any problems.

Tomatoes Cardinal

This is a mid-early hybrid variety. It is cold-resistant and easily tolerates temperature changes. From the formation of seedlings to harvesting, 99-120 days pass.

Determinate bush. Height 1.6-2 meters. It needs gartering, pinching and shaping into 1-2 stems. 5-7 fruits are formed on 1 brush. 4.5 kilograms of tomatoes are harvested from a bush per season (16 kilograms per square meter). Fruiting of the variety is extended.

Fruit weight is 200-600, sometimes 850 grams. The skin is raspberry-pink, dense, tough. The taste is sour-sweet. The pulp is juicy.

Universal use in tomatoes. The first fruits are not used for pickling in their entirety, as they are large in size. Shelf life is long. Transportability is easy.
