Potassium permanganate for strawberries in the spring is necessary at the pre-planting stage (watering the soil, root treatment), as well as during the flowering period (foliar top dressing). The substance disinfects the soil well, but at the same time destroys beneficial bacteria. Therefore, it is used in a diluted form no more than three times per season.

Is it possible to process strawberries with potassium permanganate

Potassium permanganate is an inorganic salt – potassium permanganate (KMnO4). It is also called potassium permanganate. The substance is a strong oxidizing agent. It destroys most bacteria, as well as fungal spores and insect larvae. Therefore, it performs the functions of a fungicide and insecticide, it is used as a strong antiseptic.

In moderate concentrations, potassium permanganate does not harm plants – neither the green part nor the fruits. Therefore, it is possible to water strawberries with potassium permanganate in spring or autumn. This is a good tool for the prevention and destruction of pests.

Why water strawberries with potassium permanganate

Watering strawberries with potassium permanganate is done in spring and autumn, only 2-3 times per season. The main goal is the prevention of common diseases:

  • rust;
  • spotting;
  • fusariosis;
  • different types of rot;
  • chlorosis.

Due to its high chemical activity, potassium permanganate completely destroys almost all microorganisms, including beneficial bacteria (if it enters the soil). Therefore, you need to use this remedy carefully, carefully observing the dosage – a maximum of 5 g per 10 liters.

In addition, potassium permanganate should not be considered as top dressing during strawberry flowering. Many summer residents mistakenly believe that this substance serves as a source of potassium and manganese. In fact, potassium in such concentrations is clearly not enough. It is better to use potassium salt or potassium sulfate. As for manganese, it is present in almost all soils. And this element is not absorbed from permanganate.

A solution of potassium permanganate for watering strawberries in spring should be slightly pink, not rich raspberry

Despite all the disadvantages, potassium permanganate remains a popular remedy because it:

  • totally destroys all pathogenic bacteria and fungi;
  • leads to the death of insect larvae;
  • does not accumulate heavy elements in the soil (unlike a number of chemicals);
  • affordable and easy to use.
Important! The systematic use of potassium permanganate for watering strawberries in the spring leads to a gradual acidification of the soil. pH should be measured periodically and adjusted if necessary. To do this, 100–150 g of slaked lime per 1 m XNUMX are embedded in the soil.2.

When to process strawberries with potassium permanganate

Since potassium permanganate is a potent substance that destroys not only pests, but also beneficial bacteria and fungi, it should be used with caution. Even during foliar treatment, a significant part of the solution enters the soil. Therefore, no more than three treatments are allowed per season:

  1. On the eve of planting seedlings in the spring (early April), the soil is watered.
  2. Before flowering – root top dressing (end of May).
  3. At the first stages of the appearance of flowers (early June) – foliar top dressing.

Specific terms depend on the strawberry flowering period, but in any case, the dosage should not be violated. You can also make the last application in the fall by watering the soil with a solution of potassium permanganate. This is especially valuable for areas where it is planned to plant a berry in the spring. In other cases, it is better to refrain from using potassium permanganate, replacing it, for example, with Fitosporin.

How to breed potassium permanganate for processing strawberries in autumn, spring

Strawberries can be sprayed with potassium permanganate, as well as water the soil with a solution. In this case, the concentration should be very low – from 1 to 5 g per 10 liters of water. The substance is taken in small quantities. Crystals can be weighed on a kitchen scale or determined by eye (on the tip of a teaspoon). The resulting solution should have a slightly pink color.

It is better to work with potassium permanganate with gloves, do not allow contact with eyes and skin

To obtain a solution, you must:

  1. Measure out a small amount of powder.
  2. Dilute in a bucket of settled water.
  3. Mix thoroughly and start watering or spraying strawberries with potassium permanganate in spring or autumn.

Land cultivation with potassium permanganate before planting strawberries

Potassium permanganate is often used for tillage before planting. This can be done 1,5 months before disembarkation, i.e. spring (early April). The soil is watered with a solution of potassium permanganate with an average concentration of 3 g per 10 liters. This amount is enough for 1 m2. On a bed of medium size, you will need 3-4 buckets of the finished solution.

In the spring, the site is cleared of leaves, branches and other debris, then dug up and a little sand is added – in a bucket of 2–3 m2. It will provide a lighter soil structure, which is good for strawberry roots. When watered, it retains water for a long time. Due to this, potassium permanganate is not washed out and acts on bacteria for a long time.

After watering the soil in spring with potassium permanganate, it is very important to restore the microflora (beneficial bacteria) using any biological preparation, for example:

  • “Baikal”;
  • “East”;
  • “Extrasol”;
  • “Shine”;
  • “Bisolbifit”.

This can be done a month after applying the potassium permanganate solution, i.e. about two weeks before planting strawberries in the spring. At the same moment, it is allowed to add organic matter, but not fresh manure, but humus or compost – in a bucket per 1 m2.

Important! On the eve of watering in the spring (before planting strawberries), you should not apply fertilizer to the soil.

Organics contain beneficial bacteria that will die due to the action of potassium permanganate. And mineral supplements (powder) are washed out due to the large amount of water.

Potassium permanganate treatment of strawberry roots before planting

In the spring, before planting, strawberry roots are recommended to be treated in a special solution. Potassium permanganate is rarely used for these purposes. If there were no other means at hand, you can use potassium permanganate of a small concentration – 1-2 g per 10 liters of water at room temperature. In such a liquid, the roots can withstand 2-3 hours, after which they begin to plant.

Rhizomes can be pickled in potassium permanganate for two hours

Permanganate disinfects the roots well, which will allow strawberries to avoid being attacked by pests in spring and summer. But this substance does not stimulate growth. Therefore, it is advisable to use other drugs, for example:

  • “Epin”;
  • “Kornevin”;
  • “Heteroauxin”;
  • “Zircon;
  • herbal sourdough – an infusion of the green part of the nettle, legumes with superphosphate (leave to ferment for 10-15 days).
Advice! Garlic solution can also be used as a natural antiseptic for treating strawberry roots in spring.

It will take 100 g of crushed cloves per 1 liter of warm water. Compared with potassium permanganate, this is a more gentle composition.

How to process strawberries with potassium permanganate in spring

In spring and early summer, berries are treated with a solution of potassium permanganate 1 or maximum 2 times:

  1. Before flowering (under the root).
  2. When the first flowers appear (foliar treatment).

In the first case, a complex agent is used – dissolve in 10 liters of water:

  • 2–3 g of potassium permanganate;
  • 200 g wood ash (powder);
  • 1 st. l. pharmacy iodine (alcohol solution);
  • 2 g of boric acid powder (can also be bought at a pharmacy).

All this is mixed in water at room temperature and the plants are watered (0,5 l of solution per bush). Potassium permanganate and boric acid disinfect the soil, and iodine prevents the development of a number of fungal diseases, including gray rot. Wood ash serves as a natural fertilizer, it prevents soil acidification due to the effects of boric acid and potassium permanganate. After fertilization with such a mixture, an increase in peduncles on all plants by 1,5–2 times is noted.

In the second case, foliar top dressing is carried out only with potassium permanganate in the amount of 2–3 g per 10 liters. Bushes are sprayed late in the evening or in cloudy weather. Do this in a calm and dry period. It is necessary to ensure that the solution falls on both the green part and the flowers. After that, one more spraying can be carried out using the “Ovary” preparation, which stimulates the processes of fruit formation.

Attention! A solution of potassium permanganate for watering strawberries in the spring is prepared in a small amount.

They don’t keep it for a long time. If there are surpluses, they are poured into a glass container, closed with a lid and kept in the refrigerator for no more than three days.

How to process strawberries with potassium permanganate after harvesting, pruning leaves in the fall

At the beginning of autumn, wilted leaves are cut off, flower stalks are removed. After harvesting, strawberries can also be watered with a solution of potassium permanganate, but only if:

  • in the spring there was only one treatment (so as not to violate the application rate);
  • plants are affected by fungal, bacterial or viral diseases.

Also, a solution of potassium permanganate is used for autumn watering the soil in a greenhouse or in a garden – in the area where plants are supposed to be planted in the spring. They do this to disinfect from fungi, insects and other pests. For the next season (a month before planting), it is imperative to add organic matter or water the soil with solutions of biological agents. Otherwise, there will be few beneficial bacteria, which will have a bad effect on the level of fruiting.

Advice! In autumn, it is also useful to add wood ash to the soil (100–200 g per 1 m2).

It will help the crop survive the winter, as well as enrich the soil in which they plan to plant plants for the next season.

Conclusion

Potassium permanganate for strawberries in the spring is suitable for dressing roots, seeds, and also as foliar top dressing in the early stages of flowering in late spring or early summer. To restore the microflora, after treatment, it is desirable to water the soil with a solution of a biological preparation.

Reviews on the use of potassium permanganate for strawberries under the root in the summer

Ksenia Olegovna, 49 years old, Saratov
I water strawberries under the root with potassium permanganate in early summer, when the first flowers appear. After that, I also add wood ash, otherwise in a few years the soil will become overly acidic. Because of this, the yield will fall, the taste will also be disturbed. Experience shows that one treatment is sufficient, the solution should be light pink.
Yulia Dmitrievna, 54 years old, Izhevsk
Potassium permanganate can be used 1 at most 2 times: before flowering under the root with boric acid and ash, and also during flowering (in early summer) foliar with pure potassium permanganate 3 g per bucket (10 l). We do not use it in autumn, only in the greenhouse it is possible to process the soil after harvesting. The tool is very strong, destroys all living things. But after the introduction of humus, mullein, litter, the soil is well restored.
