The use of potassium permanganate for tomatoes

Gardeners have long come to the conclusion that you can use pharmacy drugs to fertilize vegetables. The most commonly used solution is manganese. Potassium permanganate for tomatoes is an ideal treatment option, because it helps to cope with various diseases that tomato crops undergo.

The use of potassium permanganate for tomatoes

Use of Manganese Solution

Processing tomatoes with a potassium permanganate solution is the best you can think of. The cost of such a tool is low, but, despite this, it helps to prevent a large number of tomato diseases.

Advantages of using manganese solution:

  1. Due to the fact that this tool is considered an antiseptic, it is ideal for disinfecting a culture. That is, the leaves and soil completely get rid of all negative bacteria that can adversely affect the plant. But, it should be noted the disadvantage of this method. The thing is that the positive microflora of the soil is destroyed.
  2. As soon as the product enters the substrate, a chemical reaction occurs. As a result, an oxygen atom begins to be released. As soon as it interacts with the soil, ions form. It is ions that have a positive effect on the roots of the plant.
  3. If a culture is sprayed with such a pharmacy, then this also has a positive effect on the tops of the plant - it becomes stronger and more beautiful in appearance.
  4. Potassium permanganate is used to feed the soil and disinfect the plant.
  5. After pinching, manganese allows you to heal all wounds and cracks in tomatoes. This reduces the risk of infection.

Tatyana Orlova (candidate of agricultural sciences):

The full name of potassium permanganate is potassium permanganate. This chemical substance contains elements necessary for plants, manganese and potassium.

Seed treatment

  • Potassium permanganate can be processed seeds at the preparatory stage. First of all, it is recommended to spray the seeds. Despite the fact that there are a large number of funds for such processing, experienced gardeners prefer potassium permanganate as the most affordable drug.

Tomato seeds are treated with 1% potassium permanganate solution. To prepare it, dilute 1 g of the product in 1 liter of water. Watering seeds or seedlings is necessary only with warm water.

After you have selected seeds for planting, they are placed in a gauze bag. Next, the seeds are placed in a container with a solution and incubated for about 20 minutes. It is not recommended to increase the time of disinfection, since the seeds may lose their germination properties. Now you need to wash the seeds in the fabric in plain water and leave until completely dry. Please note that it is not recommended to make a very strong solution and use a large amount of a pharmacy product, because this can negatively affect the further germination and development of the plant.

Tatyana Orlova (candidate of agricultural sciences):

Inlaid seeds do not need to be disinfected with potassium permanganate. In large seed farms, tomato seeds are prepared in a certain way. They are first ground to remove villi from the surface to give them better flowability. Then a disinfectant is applied, to which a dye of a certain color is added as an indicator that the seeds are already disinfected and do not need to be pickled. Soaking such seeds before sowing is not recommended.

Manganese seed treatment will improve their quality

It is necessary to process not only the seed, but also the containers in which the planting is carried out, because harmful microelements and substances can also develop in them. To do this, you need to dilute 5 g of manganese in a 10-liter bucket of water (it is better if it is at a temperature of 80 ° C), after which all containers and soil are poured with the prepared substance.

Seedling treatment

For good tomato productivity, you need to water more than just seeds. It is very important to disinfect tomato seedlings on time. For these purposes, watering is carried out under the very root of the plant. In order for the seedlings to grow healthy, 2 waterings of the soil with a solution of manganese and 1 watering of the bush itself must be carried out.

In a 10-liter bucket, 3-5 g of pharmacy are diluted and watered at intervals of 10 days. This will destroy all harmful trace elements from the soil and on the leaves of the crop.

Planted crop care

It is often recommended to process planted tomatoes, both in open ground and in greenhouses. Such preventive measures should be carried out at least three times during the growing season.

The first time is carried out prophylaxis immediately after planting. Initially, you need to pour about 1 liter of warm water under the root. After that, it is recommended to water the tomatoes with a solution of potassium permanganate. Not only the root system, but also the stem with leaves is subject to processing. Events should be held in the morning or evening. It is very important that there is no sun. Otherwise, burns may form on the surface of the tomatoes. This procedure allows not only to feed the culture, but also to provide it with protection against late blight.

The second stage of processing should be carried out at the moment when the first flowers appear on the tomato bushes. Spraying should be carried out only after organic substances have been introduced into the soil to improve growth. It will also allow the flowers to better form the ovaries for future fruits.

The third processing is carried out several weeks before the harvest. Such actions are considered necessary, since at this moment late blight and brown spotting are actively developing. To prepare the solution, you need to grind the head of garlic and pour it with several liters of warm water. After the mixture is infused for 2 hours, the liquid must be poured into a 10-liter container. 5 g of manganese is added there and now everything is ready for spraying. You can water tomatoes with potassium permanganate 1 time in 10-15 days.


Potted potassium permanganate tomatoes can give an excellent crop. With the help of potassium permanganate, it is possible not only to disinfect seeds, but also to prevent the development of various diseases on tomatoes.
