Hello dear gardeners!
Today we want to talk about protecting tomatoes from late blight. This is a very sore subject for all gardeners. And even tomatoes with late blight are born in greenhouses. And now is just the time to start this treatment. Even with the flowering of the first brush, spraying of tomatoes begins, i.e. do not wait until some spotting appears on the leaves, but spraying begins on healthy leaves.
By the way, not only late blight threatens our tomatoes, but also other fungal diseases, in particular brown spot, which also spreads so much that tomatoes completely lose their leaves, which should not be allowed.
And once again I present the drug phytosporin, although there are other drugs against late blight. Now phytosporin is in the paste, and many do not understand how to use it correctly, because this dose is designed for a large area with a large number of plants. It turns out that if you dissolve a pack according to the norm, then people do not understand whether to pour out the rest of the solution, or ... in general, it is not clear what to do with it.
In general, detailed instructions are given on the packaging. The contents of the sachet (100 grams) should be diluted in 200 ml of water, carefully moved, and then this solution should be used in accordance with the table on the package - 2-3 teaspoons of the prepared solution should be diluted with 10 liters of water. If I dilute it with 10 liters of water, then I have enough not only for a greenhouse, but also give the remains to my neighbors. This is very good when the protection is carried out for the neighbors, i.e. late blight spores do not spread to our plants. And it is understandable, if I dissolve the whole package, how many of these teaspoons there will be ... It will be possible to supply all the neighbors in the district with this drug.
What should be done? This drug is in a paste, it can be denser, like children's plasticine, but it can be almost liquid, and people do not understand how to work with it. I'll show it now.
I cut the bag, put it on a stool and smooth it so that it is approximately the same thickness throughout the entire plane. And now I only want to use a quarter of this bag. I'm just going to try to take one fourth here with a spoon. In structure, this pasta is like our porridge. The rest I will wrap in a bag, tie and store at home in a cool room. The preparation may deteriorate in warmth.
What can you do next? Naturally, since I took the fourth part of the bag, then the fourth part of the water must be taken - not 200, but 50 ml of water. I pour all this into a bowl with phytosporin and this liquid needs to be brought to a homogeneous state, all this needs to be stirred, preferably with a fork. This paste mixes well enough. In the end, it turned out more than 2-3 teaspoons, which are needed for a bucket of water. This working solution can also be saved by pouring it into a jar and covering it with a lid. It keeps well under cool conditions. You need to stir very carefully, slowly, so that there are no lumps left. The bowl will then be easily washed off, you should not worry.
Well, let's assume that our solution is ready. Then we need to dissolve these 2-3 spoons in 10 liters of water. We will now dissolve it not in 10 liters, but in five (1.5 tablespoons). Do not be afraid to overdo it a little, since phytosporin is a biological agent, not chemistry. If you overdo it a little, it's not scary.
Then I have a wonderful sprayer called fog. I’ll give it a little bit more so that everything is well dissolved. In general, dear gardeners, only later, according to the color of this solution, phytosporin can be dissolved by eye. And we start spraying.
How to spray?
You need to try to get on all the leaves both from below and from above. You need to hit from below, because the brown spot begins to hit from below. The sprayer needs to be started from the bottom and I spray all the plants. It is better to spray in the morning, so that everything is well absorbed during the day, and so that the plant does not leave on a cold night in dampness. But the sun should not be hot either.
Such spraying on healthy leaves will save tomatoes from late blight. It is also necessary to observe the frequency of spraying. Some, you know, sprinkled it once and forgot. Both biological and chemical preparations for late blight should be used repeatedly, especially if the treated plant is in the ground, i.e. the rain passed and the preparation washed off from you. And biological preparations, depending on the weather, should be applied every 5-14 days. Next time I will do another spraying in 10 days. I have sprayed it once. There is even a harvest. Biological preparations are absolutely not dangerous, and you can eat the fruits the next day after processing, you just need to wash them thoroughly.

The most common method of introducing boric acid for tomatoes involves spraying them - spraying the solution over the green mass of the bushes.
The main advantage of spraying is considered to be fast and effective: the desired result can be seen within a few hours after treatment.
Boric acid is the most popular fertilizer for tomatoes. The main active ingredient - boron - is one of the most important micronutrients of the culture and is necessary for it until the harvest.
As an artificially synthesized effective antibiotic, Trichopolum suppresses the vital activity of fungal organisms and destroys their population.
The action of the main substance blocks the formation of nucleic acid, which disrupts metabolic processes in parasite cells.
The drug and its derivatives do an excellent job with such diseases of horticultural crops as:
As mentioned earlier, Fitosporin-M is available in the following 3 forms:
powder (light white)
in the form of a paste (dark color)
This means that the preparation of Fitosporin solutions will differ slightly from each other. But the methods of application, of course, are the same. We will also talk about them further.
By the way! The use of Fitosporin for orchids is very popular, especially for their "salvation".
By the appearance of plants, it is easy to determine that they are deficient in boron:
With a lack of boron, the bushes bloom weakly and the ovaries fall off
Since boric acid is poorly soluble in ordinary water, it must be heated to a temperature of at least +50 0 С.
Therefore, you can first dissolve the drug in a small amount, and then bring to the required volume with cool water and mix.
The proportions are as follows: for 1 liter of liquid, no more than 1 gram of boric acid is taken, which means that 10 grams of the substance (whole package) can be added to a bucket of water.
Important! The treatment is carried out using a sprayer with fine holes.
For example, for the ovary, only flower brushes are sprayed with the drug, in order to increase the sugar content of the crop - only fruits, feeding is carried out on the leaf and stems, and in the fight against late blight, it is necessary to spray the agent on the entire aerial part of the infected bush.
In pharmacies, you can buy a liquid 3% boric acid solution. Summer residents use it extremely rarely.
Diluted in 20 parts of water:
a bottle with a capacity of 10 ml is poured into a glass of water and stirred, receiving a 0.15% solution... Tomatoes are treated with it in the same way as with a powder solution. If necessary, increase the volume to the required amount.
Boric acid powder is much more popular among gardeners. It is successfully used in the complex care of tomatoes.
Boric acid is one of the most readily available remedies; it is sold freely in the pharmacy. Among its advantages, one can also mention low cost and absolute safety for people and domestic animals.
