When growing tomatoes, people often think about what drugs to treat the plants. Vegetable growers with extensive experience in working with tomatoes often use products purchased at a pharmacy: iodine, brilliant green and potassium permanganate. Newbies have many questions about the use of pharmaceutical preparations for processing tomatoes, including potassium permanganate. First, what is potassium permanganate for plants - fertilizer or antiseptic. Secondly, in what doses it should be used. Third, at what stage of vegetative development tomato processing potassium permanganate solution is most effective.
We will try to talk about the rules for the use of potassium permanganate (potassium permanganate) and the role of the substance for plants.
What is potassium permanganate
First, let's find out what kind of drug it is. Potassium permanganate is an antiseptic. Oxidizing in air, it has an effective effect on the destruction of pathogenic bacteria and pathogens of some infectious diseases.
In fact, the substance contains two trace elements necessary for the proper development of plants: potassium and manganese. Manganese and wood ash contain small amounts of manganese. These trace elements are also present in the soil, but plants cannot get them. The combination of the two trace elements increases the usefulness of potassium permanganate for the development of tomatoes.
For example, a lack of manganese can lead to interveinal chlorosis of leaves on tomatoes. Look at the photo below, what the diseased leaves look like.
Tomatoes, processed potassium permanganate, do not harm humans. They can be eaten without fear.
The value of potassium permanganate for tomatoes
Gardeners have long been using potassium permanganate when growing cultivated plants, including tomatoes, on their plots. The tool is inexpensive, but the effectiveness in the fight against some diseases of tomatoes is high.
Let's find out why processing plants with potassium permanganate is useful:
- Firstly, since potassium permanganate is an antiseptic, the treatment allows you to reduce the number of microorganisms on the leaves and in the soil, which inhibit the development of the plant. It is impossible to remain silent about the lack. As a rule, useful microflora also perishes.
- Secondly, when a substance hits any substrate, a chemical reaction begins. At the same time, oxygen atoms are released. Atomic oxygen is highly active. Combining with various substances in the soil, it forms ions necessary for the successful development of the root system.
- Thirdly, the ions of manganese and potassium have a positive result not only on the soil, but also on the green mass when spraying with a solution of potassium permanganate.
- Fourthly, the processing of tomatoes with potassium permanganate allows you to feed and disinfect plants at the same time.
- Before transplanting and during the pinching period, leaves and excess shoots are removed from tomatoes. Spraying with a pink solution of potassium permanganate quickly dries the wounds and protects the plants from infection.
Plants feel depressed if the soil was treated with a supersaturated solution of potassium permanganate before sowing seeds or tomato seedlings. Typically, yields will be reduced.
Presowing treatment of tomato seeds and containers with potassium permanganate
To grow healthy tomatoes, about disinfection you need to take care even at the pre-sowing stage. That is, to process the seeds. There are many funds available for preventive seed treatment. But we will focus on the use of potassium permanganate.
You will need to prepare a one percent solution of potassium permanganate. One gram of potassium permanganate crystals is taken and dissolved in a liter of warm water (it can be boiled and cooled to room temperature).
Selected tomato seeds, wrapped in gauze or cotton cloth, are dipped in a pink solution for about a third of an hour (longer is not recommended). After that, the seed is washed directly into the tissue under running water, laid out for drying.
Experienced gardeners can determine the concentration of potassium permanganate by eye. But beginners will have to be extremely careful, adhere to the dosage. As a rule, potassium permanganate is sold in a package of 3 or 5 grams. Here you need to be guided by the weight and amount of water.
How easy it is to process seeds:
It is not enough to process only tomato seeds. After all, disease spores can be found on sowing containers and in the ground. Therefore, boxes, tools and soil require disinfection. A five-gram bag of potassium permanganate crystals is added to a bucket of almost boiling water (bubbles begin to appear). Mix thoroughly and pour over containers and tools. Do the same with the soil.
Seedling processing
Processing tomatoes with potassium permanganate is not only preparing seeds and spraying, but also watering plants at the root. To grow healthy seedlings, it is necessary to spill the soil twice with a pink solution and spray the plants with a pink solution of potassium permanganate.
To prepare the solution, you will need 10 liters of water and 5 grams of crystals of the substance. As a rule, tillage of the soil and green mass of tomatoes, while they are on the window, is carried out every 10 days.
Plant care in soil
Preventive treatments using potassium permanganate are carried out in open or closed ground three times during the growing season.
After landing
Tomatoes are processed for the first time after planting seedlings in a permanent place after five days. For these purposes, a pale pink solution of potassium permanganate is being prepared for the prevention of late blight. In a ten-liter bucket of water, dissolve 0.5-1 grams of crystals of the substance.
Pour half a liter of solution under each plant. After that, the spray bottle is filled with a pink solution and the tomatoes are sprayed. You can also use a regular watering can. Only in this case you need to act quickly.
It is necessary to process every leaf, shoots and stems of the plant. Work should be done early in the morning so that the droplets can dry before sunrise. Otherwise, the leaves and stems are formed burns... In this case, the plants receive root and foliar feeding with manganese and potassium, as well as protection against late blight.
For processing, you will need a deep pink solution.
June
A second treatment is required when flowers appear on the very first tassels. It is carried out after feeding the tomatoes with organic fertilizers or superphosphate. The green mass is sprayed with a pale pink solution of potassium permanganate. This treatment is usually carried out in mid-June.
When fruits begin to form on tomatoes, the plants need manganese and potassium.In addition, it is at this time that late blight can most often appear on tomatoes.
Processing with a solution of potassium permanganate is a vital necessity for tomatoes. Spraying with potassium permanganate has a positive effect not only on the health of the tops, but also on the fruits.
It is no secret that phytophthora from leaves rapidly passes to fruits. Brown spots and rot appear on them. Re-processing of tomatoes with a solution of potassium permanganate falls on the end of June, beginning of July.
July August
Closer to the middle of July, in addition to late blight, the plants can be affected by brown spot. For spraying tomatoes you can use a recipe that experienced vegetable growers are always armed with. A solution is used for processing tomatoes from mid-July until the end of fruiting. We offer two recipes:
- Garlic cloves and arrows (300 grams) are minced with a meat grinder. The mass is poured with two liters of water and left to infuse in a closed jar for five days. Then the fermented garlic gruel is filtered, poured into 10 liters of water. After adding 1 gram of potassium permanganate crystals, spray the tomatoes.
- After grinding 100 grams of garlic and infusing for 3 days in 200 ml of water, you need to strain the gruel and pour the juice into a ten-liter bucket with a solution of potassium permanganate (1 gram).
Spraying tomatoes with such a solution can be safely carried out after 10-12 days. What does it give to plants? As you know, there are many phytoncides in garlic, which, together with potassium permanganate, can kill spores of fungal diseases.
Preventive spraying of tomatoes with a light solution of potassium permanganate can prevent fungal diseases.
It is especially important to spray with a solution of potassium permanganate in August, when cold dew falls. It is most often the cause of late blight in tomatoes.
Do I need to cultivate the soil and the greenhouse
No matter how carefully gardeners handle tomatoes, no matter what means they are processed, fed, the presence of pests and disease spores in the soil, on the walls of the greenhouse, all efforts can be nullified. You won't even have to think about any rich harvest.
Potassium permanganate is appreciated not only by amateur gardeners. Its unique antiseptic properties are recognized by scientists and agronomists. The fight against pests and diseases must be carried out not only before sowing seeds and during growing tomato seedlings, but also when preparing the soil.
It is no secret that even frost does not kill fungal spores in the soil and on the surface of the greenhouse. As a preventive measure, you can use potassium permanganate. A saturated solution will be required to treat the walls and ceiling of the greenhouse. Potassium permanganate is diluted in almost boiling water and sprayed on the entire surface of the greenhouse, not ignoring any cracks. Immediately, the soil is poured with a hot pink solution. After that greenhouse close tightly.
During the summer, you need to spray the greenhouse with a saturated solution of potassium permanganate, the path in the greenhouse itself and in front of the entrance. This preventive measure is necessary to destroy the spores of diseases that get inside on the shoes.
If tomatoes are grown in the open field, then the soil is also spilled with boiling water with potassium permanganate before planting.
Conclusion
Potassium permanganate, available in a housewife's first-aid kit, as a rule, is used to disinfect small wounds, scratches, and is widely used by gardeners. It is an effective means of growing a healthy and rich tomato crop.
Some gardeners process not only plants in the ground, but also the harvested tomato crop, if the slightest signs of phytophthora were noticed on the tops. Such work with green and pinkish tomatoes is especially important if the weather was unfavorable before harvesting.
For preventive purposes, one gram of potassium permanganate is dissolved in 10 liters of warm water (no more than 40 degrees), green tomatoes are laid for 10 minutes.After that, the fruits are washed under running water, wiped dry, laid out for ripening. There is no certainty that all the disputes have died, so the tomatoes are wrapped one by one in the newspaper.
We wish you rich harvests.
