Dark potassium permanganate crystals in gardening are one of the effective means for preventive disinfection and treatment of plants, and soil disinfection. Despite the fact that the drug has been included in the list of drugs subject to strict subject-quantitative accounting, today many gardeners recommend it as an effective and reliable antiseptic. Next, we will tell how to potassium and ground with potassium permanganate before planting, as well as analyze plant treatments and preventive measures.

Presowing soaking of seeds (bulbs, tubers)

Often this method is used by all gardeners and flower growers when sowing home grains. The technology is very simple and accessible to everyone: regardless of the size and shape, the entire seed must be soaked for a day in a weak solution of potassium permanganate. The liquid is prepared at the rate of 2 g per bucket of water. If the landing is planned right now, and there is no time for lengthy preparation, it is recommended to use 1 l of water for the same dosage of the preparation. At this concentration, the seeds are soaked for about half an hour.

  • boric acid (0.1 g),
  • potassium permanganate (0.5 g),
  • ammonium molybdenum acid (1 g),
  • copper sulphate (0.4 g),
  • methylene blue (0.3 g),
  • zinc sulfate (0.2 g),
  • 1 liter of water.

In the process of presowing treatment of bulbs and tubers, the main thing is to ensure that the material is completely covered with liquid. After processing it must be dried.

Soil disinfection

In cases where nematodes or undesired microorganisms and fungal mycelium have appeared on the garden bed or in the flower garden, potassium permanganate will save the day. To disinfect the area, it is sufficient to dissolve 5 g of the preparation in a 10-liter container with hot water. By the way, many vegetable growers use this method when preparing land for seedlings - in boxes, greenhouses and greenhouses.

Handling capacity tanks

In floriculture potassium permanganate is widely used not only for plants, but also for disinfection pots. To this end, before each reuse of planting tanks, they are washed with a highly concentrated solution of potassium permanganate. Moreover, the exact proportion in this case is not necessary to calculate: just dissolve the crystals, to get a burgundy liquid.

Plastic flower pots and seedling boxes just enough to rinse, but it is desirable to soak wooden containers for several hours. The tool is also recommended for spraying single peat containers and tablets.

Such processing is mandatory shown when transplanting flowers that have fallen as well as when rooting new seedlings.

Plant nutrition

On the use of potassium permanganate in gardening, there are many recipes, most often the drug can be found in complex home-made fertilizers. Often this ingredient is used alone in an aqueous solution.

In dressing you need to strictly observe the norm, otherwise the culture can be burned. Experts advise the optimal ratio of 3 g of the drug and 10 liters of water. According to them, vegetable and flower crops watered with such a liquid are less likely to get sick and become more resistant to adverse environmental factors.

You can make a substance and foliar way. But in this case, the foliage will need a more gentle concentration. Add 2 g of the drug to the bucket of water and mix well until smooth.

Disease prevention

For those vegetable growers who do not want to stuff their garden beds with poisonous agrochemistry, potassium permanganate is simply indispensable. But do not abuse the substance. In such preventive measures especially need plants that live on acidic soils. Substrates with alkaline and neutral acidity are less favorable for the development of bacteria and fungi. Often with potassium permanganate watered young stems of melon crops, strawberries, tomatoes, cabbage. These activities minimize the chances of infection with powdery mildew, mosaic, bacteriosis mucosa and any kind of rot.

Agronomists advise not only watering, but also soaking the root system of seedlings. In both cases, the same solution is prepared: 1 g of potassium permanganate is added to a bucket of water. For the purpose of prevention, 3 irrigations with a monthly interval are desirable.

Late blight (phytophthora)

At the first signs of late blight on potatoes and tomatoes, immediately prepare a solution of 1 g of potassium permanganate, a glass of garlic shooters minced through a meat grinder and 10 liters of water. All the ingredients thoroughly stir and pour the diseased plants with liquid. Also generously spray it with the stems, not excluding healthy ones. Consider that such folk remedies are effective only at the beginning of the illness (up to 3 days), and to the extent of its progression, strong fungicides will be needed.

Mealy dew

A weak solution of 1 bucket of water and 1.5 g of the drug will help to save cucumbers, strawberries and melons from this scourge. As in the previous case, the culture will need to be watered and sprinkled. But for currants, gooseberries and ornamental flowering plants, experts advise to prepare a rescue mixture of half a teaspoon of crystals and 2 buckets of water.

Gray rot

Plants that were exposed to the attack of gray rot, treated with a means of 3 g of potassium permanganate and 1 liter of warm water. During the week, twice a day this liquid is recommended to spray the buds of plants. In the case when the misfortune happened during the formation of the ovary and the maturation of greenfinches, the amount of the drug is increased by 1-2 grams.

Blackleg

If garden crops are in a humid environment at elevated temperatures, then soon a black stalk will appear on their shoots. About the vital activity of the pathogens of this disease is not difficult to guess from the highly refined and blackened stems. If nothing is done, the plant will soon wither.

To stop the destructive processes at the tissue level, you will need to remove about 2 cm of contaminated land in the tree trunk, and then treat the substrate, shoots, foliage and buds with a weak solution of potassium permanganate. It is prepared in the ratio of 1 g per 10 l. After the manipulations, place a layer of wood ash or dry river sand around the stalks.

This is only a small part of the folk methods of using potassium permanganate in the garden and in the garden. But do not forget that they are effective only at the first stages of the development of microorganisms, and with mass foci of infection only potassium permanganate is indispensable. Do not be afraid to use this medication and Do not forget the sense of proportion.

Record Navigation

More than one generation of farmers used a chemical such as potassium permanganate, in gardens and vegetable gardens. Today, anyone who wants to use potassium permanganate in his garden is far from being able to buy it in every pharmacy (as potentially explosive and suitable for making drugs, it is ordered to be stored in special conditions, there are quantitative restrictions on pharmacy sales). Of course, a lot of new agricultural preparations appeared, but many continue to give preference to habitual potassium permanganate when working in the garden. People are attracted by efficiency, ease of use, certain efficiency, relative harmlessness to humans.

What can potassium permanganate

Of course, like many concentrated chemicals, potassium permanganate is not at all harmless. First of all, it is a disinfectant that, in strong dosages, is capable of burning representatives of the flora and fauna. For young children, ingestion of three grams can be deadly, for adults - from twenty grams (this is a teaspoon with a slide). In small quantities, manganese is not considered a microelement that is very toxic to humans, but the long-term cumulative effect can be harmful (in the long run, fatigue, memory impairment, allergies, mutations). This should be remembered by those who like to often and abundantly shed the beds with a strong solution of potassium permanganate. It should also not be forgotten that such an impact has a detrimental effect on beneficial soil microorganisms.

It is clear that potassium permanganate contains potassium and manganese, but the fertilizing properties of this chemical compound are negligible, in the garden we use manganese primarily as an assistant — an antiseptic that kills unwanted microscopic organisms — harmful for plants, fungi, bacteria, and viruses. And since a lot of things relate to the garden, including tools, and other subsidiary, consider its help to everything.

Pretreatment of planting tanks

Before re-using seed pots, drawers, pallets (of any material) it is very useful to wash them with a strong (burgundy) solution of potassium permanganate. Wooden boxes in it, you can briefly soak.

With a similar composition, we spray single-use peat pots and tablets to prevent the development of mold on the walls.

Strait spreading ground

Some summer residents before home sowing of seeds for seedlings consider it their duty to shed containers filled with substrate with hot potassium permanganate (rich pink color). Sometimes this measure really helps in the prevention of black legs (especially with shaded, coldish windowsills). If this disease begins to "mow" the seedlings, disinfecting irrigation usually does not help any more, drying the soil is much more useful.

Strong potassium permanganate pickle the ground for one-year asters (prevention of fusarium wilt).

Preseeding treatment of seeds

Seed material of many cultivated plants can be infected with invisible spores of pathogenic fungi (blight, fusarium, anthracnose, keel, and many others.). Soaking seeds (on the eve of sowing on seedlings or in open ground) in many people in the potassium permanganate practice, but not always correctly. The bottom line is that low concentrations have no effect. The correct event is carried out with the use of a strong, dark pink solution (1 g per glass of water). Seed material is kept in it for a quarter of an hour, then washed in clean water. It is important for crops from such botanical families as solanaceous (first of all, tomatoes, as well as peppers, eggplants, potatoes from botanical seeds), pumpkin (especially cucumbers, melons), cruciferous (cabbage, radishes, radish), and also for black onions.

For seeds of annual asters that are susceptible to Fusarium, we take twice as strong concentration, after 20 minutes we quickly rinse with clean water. Then lightly dry and sow.

Processing potassium permanganate flower planting material and onion sets

Before planting flowers with bulbs, tubers, rhizomes, soak them for 30-60 minutes in pink potassium permanganate (1 g per 2 liters). It can be tulips, lilies, gladioli, begonias, calla lilies, cannes, hyacinths, dahlias, etc. We make similar processing before putting it into storage. We apply the same dosage before planting onion seedlings.

Disinfection with potassium permanganate buildings and equipment

With a saturated concentrate of potassium permanganate we wash in the garden at the beginning and end of the season the frames and the cover of greenhouses, cellars, greenhouses. We do the same with tools, rubber shoes, reusable gloves, pegs, trellis, etc.

Knives, pruners, scissors are regularly disinfected when carrying out any pruning in the garden (so that the juice from possible diseased plants does not infect healthy ones).

Disinfection ridges

If we consider it necessary to pickle the ground in the garden (from fusarium asters, bulbous rot, keels and black leg of cabbage, root rot of cucumbers, late blight of tomatoes), then the surface of the ridges (or purposefully planting pits) is spilled with potassium permanganate (dessert spoon 30 liters of water).

Description of potassium permanganate, its properties

Potassium permanganate KMnO4, also commonly referred to as potassium permanganate, is a small crystal formation of dark purple color. This substance quickly dissolves in water, as a result of which it becomes pink or purple (depending on the concentration of the solution).

The composition of potassium permanganate consists of three components:

When released into a suitable medium, the substance begins to decompose rapidly, in the course of which a large amount of active oxygen is released. The latter is especially dangerous for bacteria and fungi. In this regard, potassium permanganate is widely used in medicine. A solution of this salt is used to treat wounds, burns, caress the mucous membrane of the throat, wash the stomach in case of poisoning.

Attention! It should be remembered that if proper concentrations are not observed, this salt can greatly harm living tissues. A large amount of oxygen released can leave burns on the body. Therefore, use the substance with extreme caution.

The use of potassium permanganate in the garden

Due to the effective antiseptic action of potassium permanganate has found wide application in the areas of gardeners. With its help they disinfect the soil, carry out preventive treatment of seeds from infections, process inventory and containers used for planting seedlings. The substance is also effective in combating various cruciferous diseases.

Disinfection of planting containers and inventory

With repeated use of the same containers for seedlings, they can accumulate and persist pathogens of various diseases. When planting a new batch of vegetation in the same container, fungi and bacteria become more active and badly damage the seedlings that have not yet become stronger. As a result, all the seedlings may die.

How to water cabbage seedlings with potassium permanganate

In this case, potassium permanganate solution is an extremely effective remedy, which is used as follows:

  1. About 18 g of potassium permanganate (3 tsp) are poured into a bucket of water (10 l) and mixed thoroughly until the liquid is completely colored.
  2. Boxes and pots are cleaned of dirt and rubbed with a damp cloth.
  3. Each container is thoroughly washed with a previously made solution.
  4. If the container is made of wood, it is soaked for a few minutes so that the agent will act on the pathogens that live in the pores of the material.

Sowing seeds in such containers is carried out immediately after they are dried in the sun.

Important! Infections from plant to plant are also transmitted through the working garden and garden tools. To disinfect the inventory it is also thoroughly washed with a solution of potassium permanganate. Only in this case, the salt concentration in water is increased to 6–7 g per liter.

Disinfection of soil in the garden

Potassium permanganate helps in the fight against bacteria living in gardening years for years. When used for this purpose, the solution is made as weak as possible. For every 10 liters of water add no more than 5 g of the substance. The salt is stirred until it is completely dissolved in the liquid.

With the help of a watering can plentifully shed the whole area with a solution with a solution. Of course, the infection and fungi that are in the depths of the soil, this tool will act weakly, but in the upper layer of soil can easily destroy any pathogens.

It should be remembered that the introduction of potassium permanganate in the soil significantly increases the level of acidity. Fluxing of hydrated lime over the surface of the soil and its digging after watering with the solution helps to restore its initial level.

Cabbage Seed Treatment

Before sowing cabbage seeds in open ground or containers, experienced gardeners must prepare seed. It includes the sorting of the seeds, their hardening, keeping in solutions of bioactive drugs.

It will also be useful to include soaking of seeds in potassium permanganate in this list. This procedure has several objectives:

  • disinfection of seeds, on which bacteria and fungal spores can persist,
  • improved seed germination,
  • increase the shelf life of seed.

Application of potassium permanganate solution

For soaking, a solution is prepared in which 1 g of potassium permanganate is added to each liter of water. After thoroughly mixing the composition, seeds are poured into it and kept there for 15 minutes. Too much of the procedure should not be, otherwise the seeds can get burned.

After soaking, the seeds are removed from the solution and washed with copious amounts of warm water. Then they are laid out on the fabric and dried.

Greenhouse disinfection

Potassium permanganate is an effective means of preventing vegetation diseases in greenhouses and greenhouses. For convenience, their processing can be combined with washing containers and tools.

For work prepare solution in concentration of 3 full teaspoons of crystals on 10 l of liquid. Since the treatment is carried out indoors, it is necessary to put on long-sleeved clothing, rubber gloves and a mask on the face before disinfection.

The whole procedure is carried out in the following order:

  1. All tables, containers, tools, remnants of construction and other debris are carried out of the greenhouse. All the necessary tools and accessories are processed in parallel from the outside.
  2. Раму и стенки конструкции тщательно промывают обычной водой.
  3. При помощи губки приготовленным раствором обрабатывают элементы каркаса. Дальше моют стекла, обеззараживают пол.
  4. После окончания проведения процедуры внутри теплицу дополнительно обрабатывают снаружи.

Attention! At the end of disinfection in the greenhouse, all doors and windows open wide, leaving it in this form for 2-3 days. Only after that all inventory, shelves and containers are brought back.

Prevention of fungal and bacterial diseases of cabbage

As already noted, the antiseptic effect of potassium permanganate helps well in preventing and combating various diseases of cabbage. The most effective composition against the following ailments:

  1. Mealy dew. This fungal disease is manifested by a white or gray bloom on cabbage leaves. Their processing should be carried out after identifying the first signs of illness. For the treatment of 3 g of crystals diluted in a bucket of water. Liquid carefully water the plants and the ground around them. The procedure is repeated 2 more times.
  2. Late blight. The disease also has a fungal nature. It affects the stem and roots of cabbage leaves, reducing the time of its storage. To combat it, prepare a solution consisting of salt of potassium permanganate and garlic. The latter is ground to obtain a homogeneous fine fraction. Every 100 g of this mass is poured with warm water (200 ml) and allowed to infuse for several hours. In the infusion add 1 g of permanganate and dilute the composition in a bucket of water. The treatment is carried out by spraying every 10 days.
  3. Blackleg. This disease is considered one of the most dangerous for cabbage seedlings and does not imply effective treatment. Therefore, the treatment with a solution of permanganate is carried out as a prophylactic measure. To do this, in a bucket of warm water, add 5 g of crystalline matter and mix. A solution in small quantities poured under each bush.

Black leg of cabbage

In the processing of cabbage with potassium permanganate it is important not to exceed the indicated concentrations of the composition and rate of irrigation. If you do not follow the specified values, you can easily burn the leaves and roots of young plants, which will lead to delays in the development, and in the worst case, the death of all plantations.

Top dressing cabbage with potassium permanganate

Potassium permanganate also shows a certain effectiveness as a fertilizer for cabbage. Periodic irrigation of culture with such a tool contributes to the growth of growth and development of culture. But as is the case with other methods of applying the solution, here you should strictly follow the recommendations on the use of the substance. Otherwise, you can only harm the well-grown vegetation.

Why water the cabbage with potassium permanganate?

The use of potassium permanganate crystals dissolved in water as a top dressing is possible due to the positive effect that this solution has on plants. One of the components of the molecule of such a substance is potassium. In the period of growth of cabbage seedlings, young seedlings are in dire need of such a trace element, because it:

  • plays an important role in carbohydrate metabolism,
  • helps to strengthen the stalks of the bush,
  • increases drought resistance of vegetation:
  • strengthens the plant's immunity to powdery mildew,
  • improves nitrogen metabolism
  • promotes more active passage of photosynthesis in green plant tissues.

Manganese, which is part of the permanganate, is one of the components of many plant enzymes. In addition, it also increases plant resistance to drought, plays a role in the process of photosynthesis. The high content of manganese in cabbage cells contributes to a more intensive production of vitamin C and an increase in the amount of sugar in cabbage leaves.

It should not be forgotten that the antiseptic effect of the agent resists pathogens of many fungal diseases. Accordingly, the plant does not spend strength on combating such an infection, which means that all the energy it generates goes to the growth and development of the plug.

Rules of preparation of the solution

For feeding cabbage plantings use a weak-pink solution of permanganate. The recommended concentration in this case is 3 g for every 10 liters of liquid. Prepare a solution in a bucket. Water for the mixture is better to take warm. So the crystals dissolve faster in it.

Weak pink solution of permanganate

In the prepared distilled and heated water pour the specified amount of salt. Then the whole composition is stirred until the substance is maximally dissolved. After that, carry out watering.

The above dosage of the substance must not be exceeded. A more concentrated solution will leave severe burns on the roots and leaves. In addition, an excessive amount of potassium in the soil adversely affects its overall fertility.

How to water the culture with potassium permanganate

Water the plant from the watering can. Moreover, the bulk of the solution is poured under the root of the plant. But a small part is also recommended to spray on the leaves. So the bush will be able to absorb more nutrients.

Watering is carried out in the evening, when the foliage does not fall into direct sunlight. Water is uniformly sprayed not only on the plant itself, but also partially on the ground between the rows. The most favorable time for the introduction of such fertilizer is the end of June - the beginning of July.

Regular potassium permanganate, which can often be seen in a home first aid kit, can be very useful for a summer resident in caring for a garden. Possessing high antiseptic qualities, this tool will help to disinfect the working tool, the seeds before planting, to disinfect the soil on the site. In addition, the components of this salt are extremely useful for cabbage. They enhance the metabolism in plant tissues, protect bushes from disease and drought. As a result, such dressing can significantly increase yields from cabbage beds.

2. Disinfection of seedlings containers

A concentrated solution of potassium permanganate is useful for disinfecting seedling containers, if it has already been used to grow plants in previous seasons. Plastic pots and boxes can be simply washed with an antiseptic, and wooden containers should be soaked in such a mixture for several hours.

4. Feeding

Manganese is an indispensable plant nutrient. Its lack of soil adversely affects the development of cultivated plantations, reduces their immunity and yield. The first signs of manganese starvation are the variegated coloration of young leaves, when the veins remain green and the rest of the leaf-sheet fabric becomes yellow or fawn.

It is worth noting that in acidic soils there is often a surplus of manganese, and in those areas where the reaction is neutral or alkaline, this element is in insoluble form and is not available for plants. Therefore, in the latter case, it makes sense 2-3 times a season with an interval of 2-3 weeks to give your green pets a root or foliar top dressing with a weak pink solution of potassium permanganate. It will positively affect their development and increase resistance to adverse factors.

6. Phytophlorosis

Potassium permanganate is indispensable for the prevention of late blight of solanaceous crops. To avoid the appearance of this insidious disease on tomatoes, peppers, eggplants and potatoes, during the season, the bushes are abundantly sprayed with a therapeutic elixir every 12-14 days. For its preparation, 10 l of a weak-pink solution of potassium permanganate is induced, 200 g of cloves of garlic passed through a press are added and the mixture is allowed to stand for half an hour. Then infusion filter, add 1-2 tbsp. spoons of liquid soap or shampoo and handle planting.

9. Disinfection of greenhouses and cellars

The powerful antiseptic properties of potassium permanganate allow it to be used for effective disinfection of the walls and frames of greenhouses and greenhouses, as well as shelves and shelves in the vegetable storehouse. They impose a strong solution and thoroughly wash them from inside the closed ground room. Do it in the spring shortly before the start of planting.


Strong solution of potassium permanganate disinfect the walls of the greenhouse

In the same way come in preparing the cellar for the laying of a new crop. The metal parts of the shelves of the vegetable store are washed with a solution, and wooden shelves and crossbars are soaked in it for several hours if possible and then dried in the sun.

10. Disinfection of garden tools

A strong solution of potassium permanganate is a simple and inexpensive means for disinfecting numerous garden tools. Secateurs, scissors, knives and saws are treated with this mixture before each use.


The solution of potassium permanganate is a simple and inexpensive means for disinfecting garden tools.

The procedure is also carried out at the end of the summer season before harvesting garden equipment for storage. The rest of the range of country assistants — shovels, pitchforks, rakes, choppers, etc. — is connected to the cutting tool. You need to prepare a wide basin with a solution, wear gloves and carefully wash the working part of the tools with a liquid antiseptic. After that, the inventory is dried, if necessary, lubricated with oil and sent to "rest" until the next spring strada.

As I said, potassium permanganate can be purchased not only in a pharmacy, but also in shops for gardeners. For example, you can find it in our market by clicking on the link.


Potassium permanganate bribes with its efficiency and economy, therefore it occupies an honorable place in the summer medicine cabinet of many gardeners. Despite its chemical origin, this drug is safer to use compared to many other antiseptics and fungicides. The main thing is to prepare the solution correctly, carefully diluting the powder crystals in water, and avoid storing the drug at high temperature.

Dear readers, if you have already tried the above methods of using potassium permanganate, share your opinion on the effectiveness of this drug in the comments. And if you know other options for using potassium permanganate in the dacha farm, be sure to tell us about your positive (or negative) experience.

How to dilute the potassium permanganate for medical purposes

The main rule is to maintain clear proportions while preparing the solution, otherwise potassium permanganate will become a dangerous irritant to the skin and mucous membranes. For processing most often used 0.1-0.5% solution. The weakest solution of potassium permanganate is used to rinse the mouth and throat. External purulent wounds, burns allowed to lubricate 2% of the composition.

On a note! To prepare a weak solution for 1 liter of water, add 2-3, stronger ones - 3-4 grains of substance. To dissolve faster, you can use warm water.

A solution of potassium permanganate for any procedure should always be fresh.

When preparing the solution, be sure to observe the following safety regulations:

  • do not touch the grains of potassium permanganate with your hands, but take them with a spoon, a match or a toothpick,
  • stir the solution thoroughly until the grains are completely dissolved so as not to get burned,
  • do not store the finished solution,
  • use personal protective equipment while working with the product.

IMPORTANT! Keep potassium permanganate out of the reach of children and animals. Do not leave the substance in the sun.

How to breed potassium permanganate for processing plants

Useful properties of potassium permanganate are successfully used by summer residents and owners of indoor plants. For plants, solutions are prepared a little differently; the amount of potassium permanganate is measured in grams and diluted in a large volume of water. If you do not have scales, take a teaspoon to measure. For the preparation of the solution is best to use transparent glassware.

On a note! In 1 tsp. without slides contains about 6 grams of potassium permanganate

And now we will consider 14 popular ways of using potassium permanganate in the garden, garden and flower garden.

Disinfection with potassium permanganate

Potassium permanganate perfectly cope with the disinfection of planting containers, flower pots and pallets. Prepare such a solution for the procedure: dilute to 3 tsp in 10 l of water. potassium permanganate. Wash the plastic containers with the resulting composition and soak the wooden containers for a short time so that they become saturated with the substance. Then dry everything thoroughly and start planting.

Pickling potassium permanganate soil for seedlings

Once the landing tank is ready, it's time to do the ground. And first of all it needs to be sanitized, or pickled. No matter what soil you use. Even if it is bought in a store or brought from a summer cottage, and not collected in the nearby forest, it is better to insure and use potassium permanganate. Dissolve 5 g of potassium permanganate in 1 l of water, mix thoroughly and pour plenty of soil. Now you will be sure that you protect future shoots from diseases and pests!

Important!

To enhance the effect of the mixture, preheat the water to 70 ° C. After the procedure, seeds can be planted only in cooled and slightly dried soil.
