The use of potassium permanganate for onions

Novice gardeners are often faced with the shooting of sowing onions, which does not allow them to grow large, dense heads. Why does this happen? Often the reason lies in the improper preparation of the seedlings - experienced gardeners are well aware that before planting in the ground, the onion must be treated with potassium permanganate, this helps to protect it from death.

Buying ready-made planting material, you can save yourself from the difficulties of germinating seeds. This approach can significantly reduce the time and effort spent by the gardener. However, in this case, there is no guarantee of the health and sterility of the seedlings. It so happens that the summer resident lays the onion set in the ground, takes proper care of it and waits for a rich harvest, but the result is disappointing:

• soft heads;
• signs of rot;
• small onions;
• mass destruction of the product, as a result - a reduced yield coefficient.

Most often, the reason is the lack of disinfection of the purchased product. It is profitable for the merchant to have time to sell all the harvested seed material as soon as possible, and the more - the better it will be for him. Therefore, seedlings are often treated with special chemicals to keep them fresh. Of course, there are exceptions - those people who think about a stable client base and pay special attention to the quality of the planting material sold. But, as practice shows, the share of such sellers does not exceed 15%.

That is why every product bought on the market or in a store must undergo mandatory additional processing. To do this, use special tools - they allow you to get rid of all types of surface contaminants, such as dust and special reagents. In addition, disinfection neutralizes pathogenic microorganisms that often inhabit the seedling. Such a solution shows high efficiency against onion flies.

Nowadays there is a wide range of seedbed preparation products. Unfortunately, not all of them are safe for people. Some brands introduce chlorides into their formulations, which, when entering the human body, accumulate and cause damage to health.

Potassium permanganate is an antiseptic known to every person. It has been used by humans for a long time. It is widely used in medicine for the treatment of wounds, inflammations and for gargling. A little later, this antimicrobial agent began to be used in agriculture.

The benefits of potassium permanganate for onions are undeniable:

• protection of seedlings from wintering pests due to a pronounced antiseptic effect;
• potassium permanganate is a good foliar feeding, which supplies the green parts of the onion with the trace elements it needs for full development;
• due to the antifungal properties of permanganate, the defeat of fungal spores is achieved.

Permanganate is also used for soil preparation. but do not rush and fill the entire area with a solution based on potassium permanganate. This is primarily a chemical compound, and if used improperly, it can harm a person - provoke pathologies of the skeletal system, cause burns on the skin and mucous membranes.In addition, an excess of manganese salts impairs the productivity of the soil.

The use of potassium permanganate for soil cultivation has its limitations. It is used only for irrigating land with a neutral or alkaline reaction. If you neglect this recommendation, then you can significantly reduce the fertility of the substrate and even partially lose the crop.

There are several techniques for processing onion sets and planting beds with potassium permanganate. They are distinguished by the saturation of the active composition, as well as the processing time of the seedlings. Usually, several recipes for working solutions are used - weak, concentrated and strong.

This composition is prepared from 3 g of powder dissolved in 1 liter of water. It takes about 2 hours to soak the planting material. Such a solution is characterized by a reduced concentration of the main component, respectively, the strength of its effect is less. This means that the harmful effect on seedlings is also reduced. Experienced gardeners assure that treating onions with a pale antiseptic solution before planting is the best option. Although some gardeners claim that in this case, some bacteria remain viable.

The concentrated preparation is in the proportion of 10 g of crystals per liter of water; potassium permanganate must be diluted with strictly warm liquid. Seed material is soaked in solution for 40-45 minutes. It is essential that the liquid is warm. Such treatment completely destroys fungi and pathogenic microorganisms. but it should be remembered that if such a composition can destroy all living things, then it is possible that the set itself will be damaged.

A highly saturated solution is made from 25 g of powder dissolved in 1 liter of warm water. Onion sets can be kept in it for only a quarter of an hour. Such a processing option is permissible only in cases where there is a suspicion of infection of the planting material with a fungus. The fact is that this is a pretty strong line-up. Accordingly, it can harm the bow itself.

So, if you bought onion sets or onion seeds from the store, you need to prepare the seedlings for planting. To do this, follow these steps.

• Examine the seeds carefully. Damaged specimens must be removed from the bulk.
• It is better to remove the top of dry seeds, in this way germination can be significantly improved.
• Drying of seeds should be done in spring. To do this, they are laid out on a hard surface and kept for a couple of days at an ambient temperature of 25 degrees.
• The main step is to soak the planting material. To do this, take a container with water, dissolve table salt in it at the rate of 1 tsp. 1 liter of clean water and leave the seeds there for two to three hours.
• After that, it is necessary to carry out disinfection - it is at this stage that potassium permanganate will be needed. The solution must be fresh. Perform the procedure right before planting, otherwise the solution will lose its antifungal and antimicrobial characteristics.
• After disinfection, the seeds should be re-dried. It is needed to prevent rotting of the product. Immediately after that, you can proceed to planting work.

If you process the onion sets in potassium permanganate, you can rid the seed of most types of fungi, bacteria and viruses that have settled in it. However, attention should be paid not only to the onion, but also to the substrate in which it will be planted. For this, the same solutions are used - and if you do not need to cultivate the land with salt, then potassium permanganate is desirable.

For disinfection and fertilization of the substrate in spring, extremely weak solutions of permanganate are used. To do this, dissolve 5 g of the drug in 10 liters of water. Crystals of potassium permanganate should dissolve completely and give the solution a pale pink color, the water should be warm.

Water the ground with an ordinary watering can, moisture must be distributed evenly over the garden. It is only necessary to cultivate the top layer of the earth, into which the onions will be sown, which is why one watering can is usually enough for seven to eight square meters of the sown area. This watering is done a couple of weeks before planting onions.
