How to protect tomatoes from phytophthora

Every year phytophthora comes on planting tomatoes. And with each season, tireless gardeners come up with new ways to deal with it. All methods are divided into two types: prevention and saving the remaining crop. The first are used on healthy plants and are designed to prevent the onset of the disease. The latter are used when the phytophthora has already appeared, and are often aimed at accelerating the ripening of fruits.

In any case, both options are suitable both for open ground and for shelters. But how to protect tomatoes from phytophthora, now tell.

Preventive methods

Bordeaux mixture. Many refuse to use this drug. Allegedly because of the chemistry that accumulates in the fruit. What nonsense! Bordeaux mixture is not absorbed in vegetables. It covers them with a film that prevents infection. Tomatoes can be eaten already on the first day after spraying.Naturally, only after thorough washing.

The solution is prepared according to the instructions on the package. Keep it undesirable, it is better to use immediately. Phytophthora is afraid of copper ions, therefore spraying is carried out all season, with an interval of 13-15 days. This will allow you to update the protective film after watering and rain. The first spraying is carried out a week after landing in the ground, then according to the schedule.

Council It is necessary to wet leaves, stalks and fruits carefully and from two sides. Before the appearance of drops.

Garlic and potassium permanganate. Antibacterial properties of plants help in the prevention of phytophthora. Potassium permanganate is an antiseptic.

It is not necessary to use the teeth themselves. You can take the stems, leaves, arrows. They are ground in a meat grinder or very finely chopped. Then take 100 ml of pulp and 1 g of potassium permanganate per 10 liters of pure water, mix thoroughly. Then filter and spray the tomatoes.

The frequency of treatments is about 1 time in 2 weeks. So you can be sure that the fungus will not pass.

Council Do not throw away old sprouted heads. They are quite suitable for the preparation of the mixture.

Kefir and iodine. At 10 liters of ordinary water, add 0.5 liters of old kefir and 21 drops of alcoholic tincture of iodine. Stir, filter. Spray the tomatoes 1 time in 10 days.

Milk helps the mixture to stick to the plants and forms a protective film on the surface. And iodine is known for its antimicrobial action.

Council You can not increase the proportions of iodine. This can cause leaf burns and shoots.

Stinger 200 g of live weight finely chopped, add 2 liters of boiling water. After cooling, filter and spray the tomatoes. Spores of the fungus do not harm the plants, but do not allow the phytophthora to cling to them. It is enough to carry out processing 1 time in 3 weeks.

Council Instead of slicing, you can try to scroll tinder through a meat grinder or grate. The older the fungus, the stronger the protective effect from it. But the harder it is to grind.

Phytosporin. These are cultural bacteria that do not allow germination of late blight spores. The solution is treated with the soil before planting, after harvesting. During the growing season they sprinkle the roots of tomatoes on them, spray the green mass and the fruits themselves.

All instructions for preparation and use can be found on the packaging of the drug.

What to do if tomatoes are already amazed

Save the remaining crop. Do not rush to pick green tomatoes.If the infection has already happened, they will still rot. Yes, and give the sore healthy fruit. It is better to spray the bushes with a special solution. 200 g of salt is dissolved in 9 liters of pure water.

After this treatment, leaves, flowers and young shoots will die. But healthy tomatoes ripen much faster. This will save the crop.

By the way, saline solution allows you to identify already sick tomatoes. The day after spraying, the site of infection will turn brown or brown. This will help get rid of the affected fruits, and have time to cook a salad of green tomatoes, pruning a sore spot. All the same, they no longer mature.

A similar effect has a strong solution of urea. It also burns the leaves and makes the tomatoes ripen faster. To prepare it, you need to stir a good handful of fertilizer in 10 liters of pure water. If you do not want to mess around with gloves, then just take 1 glass of 200 ml. Although gloves are still needed - we must not forget about safety during spraying.

Follow the weather forecast. If they promise a long or fast cooling, the tomatoes will have to cover with non-woven material with a film.Of course, with a large area of ​​planting, this is problematic, so here it is necessary to collect immature fruits and lay them somewhere for ripening.

Handle greenhouses. After harvesting in the fall and before planting in the spring, you need to burn the tobacco or sulfur bills inside. In this case, be sure to close the vents and doors. It is desirable to treat the arcs and frame with a solution of copper sulphate. For the winter, it is necessary to open the doors wide, so that the frost helps to destroy the pathogenic spores of the fungus and bacteria.

Remove diseased plants. If the symptoms of phytophtora are seen in isolated cases, then it is better to be safe. It is necessary to tear out the affected tomato with the root, take it out of the site and burn it. The land where the diseased shrubs grew will have to be treated with copper or phytosporin. You can shed heartily with a strong solution of potassium permanganate. The main task - to prevent the spread of filth on other plants.

Protective agrotechnology

Using sprays is only part of protecting tomatoes from phytophthora. Be sure to comply with competent agrotechnology, coupled with spraying.

You can not thicken landing.They will be poorly ventilated, and the phytophthora loves high humidity. For additional protection, you should remove the extra stepchildren and all leaves that reach the ground. It is better to remove the leaves before the first brush.

Compliance with crop rotation is also a protective measure against phytophtora. For example, tomatoes cannot be planted where any solanaceous crops grew in the past year. They have the same ailments and pests.

Tomatoes can not be watered and sprinkled too often. This should be done strictly under the root, so as not to provoke an outbreak of the disease. And be sure to give to dry the top layer of soil to a depth of at least 3 cm.

Do not neglect the prewinter soil digging. It helps frosts kill the disease spores that remain in the ground. In the spring, it is imperative to treat the soil with copper, a solution of potassium permanganate or phytosporin. Thus, the maximum level of security is achieved.

Timely and fully need to feed the tomatoes. Healthy strong plants themselves can keep up the pressure of pathogenic fungi for quite a long time. Weakened and frail get sick almost immediately after the activation of the dispute.

It is recommended to plant ultra-early varieties. They have time to give most of the harvest before the arrival of cold August nights. Or varieties that are resistant to diseases.

How to protect tomatoes from phytophthora? This is a whole range of activities. Moreover, it is performed regularly. One spraying is not enough. You need to combine different techniques to get a good result. We'll have to work hard to sore not ruined the crop overnight.
