Watering cucumbers with potassium permanganate is done 2-3 times per season. This helps saturate the soil with potassium and disinfects it from fungi, bacteria and other pathogenic microorganisms. The standard solution is prepared based on a ratio of 3 g per 10 liters of water. This is a safe concentration that should not be violated. Otherwise, the leaves will get burned, and such treatment will cause much more harm than good.
Why water cucumbers with potassium permanganate?
Potassium permanganate is dark purple crystals. Chemically it is potassium permanganate KMnO4. Thanks to this composition, the substance performs two important functions:
- Soil disinfection, destruction of fungal spores, pathogenic bacteria and other microorganisms.
- Saturation of the soil with potassium - a vital element necessary for all plants.
Using a product for watering and spraying gives cucumbers great benefits:
- Prevention of dangerous fungal infections (powdery mildew, anthracnose, cladosporiosis, gray rot).
- Improving metabolism due to the intake of potassium.
- Ensuring normal growth and productivity.
- Protecting cucumber seeds from fungi, bacteria and other pests living in the soil.
Features of preparing the solution
Manganese should be diluted for spraying cucumbers in warm water. Cold liquid should not be used, as the crystals may not disperse. If they get on the plants, the leaves or stems will be severely burned and may even die.
The concentration depends on the purpose of the treatment:
- for seed dressing – 10 g per 1 liter;
- for foliar treatment – 3 g per 10 l;
- for watering the soil before planting - 3 g per 10 l;
- for treating the walls of the greenhouse and the soil around it - 50 g per 10 liters.
Preparing the solution is quite simple. You need to do this:
- Measure out the required amount of powder.
- Dissolve in a small volume of warm water.
- Stir thoroughly.
- Bring to total volume (1 l or 10 l).
- Mix again.
- Water the soil or pour it into a sprayer and treat the cucumbers.
The solution used for treatment should be pale pink in color.
Methods of using potassium permanganate for cucumbers
Potassium permanganate is used for various purposes - seed treatment, root and foliar treatments. The concentration of the solution depends on this, as well as the timing and frequency of treatments.
Seed treatment
To treat cucumber seeds, you need to prepare a 1% solution, i.e. 10 g per 1 liter of warm water. The liquid is thoroughly mixed. Then the seeds are placed in it and kept for no more than 20-30 minutes. After this, they are washed under running water, and then planting begins. It is advisable to first soak the seeds in a 5% salt solution. If any pop up, they can be immediately rejected.
Watering the soil and holes before planting
Potassium permanganate serves as a powerful antiseptic. The solution destroys bacteria, fungal spores and other pathogenic microorganisms. Therefore, a solution of potassium permanganate is used not only for processing the cucumbers themselves, but also for watering the soil. The day before planting seeds in open ground or for seedlings, it is recommended to water the soil with a solution of low concentration (3-5 g per 10 l).
There are alternative ways to disinfect soil for growing seedlings. The soil can be kept in the freezer for several days or in the oven for 20-30 minutes at 150 degrees.
On the eve of transplanting cucumber seedlings, it is recommended to water the prepared holes with potassium permanganate. In this case, it is not necessary to use potassium fertilizers, since after treatment the soil will already be saturated with potassium.
Watering cucumbers with potassium permanganate during fruiting
Manganese solution is also used to treat cucumbers in open ground and in a greenhouse during fruiting. To do this, you will need a liquid prepared from a ratio of 3 g per 10 liters. Water is poured under the root, as well as around the bush. Treatment is carried out in the late evening or early morning.The weather should be good - without strong wind or rain.
During fruiting, cucumbers are watered with potassium permanganate 2-3 times.
Irrigation is usually done in June to prevent potassium deficiency. This problem can be detected by a number of signs:
- weak growth already in the early stages (after transplanting seedlings into the ground);
- lengthening of internodes;
- loss of color by leaves (color becomes light green);
- the appearance of spots on the tops;
- withering and falling off (neglected state).
Potassium moves through the soil slowly, so even if you water the soil with potassium permanganate, you won’t be able to get a quick effect. To speed up the process, it is also necessary to do foliar treatment per leaf. This is especially important when dead areas, spots and other signs of acute potassium deficiency appear on the leaf blades.
Spraying cucumbers with manganese solution
Potassium permanganate is also used for foliar treatment of cucumbers. This is done to saturate the vital element potassium and prevent diseases and pests. For work, take a solution of standard concentration - 3 g per 10 l. Moreover, it is advisable to spray not once, but 2-3 times per season.
Timing and frequency of treatments
Potassium permanganate is a potent substance. Therefore, when processing cucumbers, it is important to take into account not only the dosage, but also the frequency and timing. Summer residents are advised to follow these rules:
- Cucumber seeds are treated on the day of planting. It is enough to do this once, and you should not keep them for too long - a maximum of 30 minutes. The processing time is at the end of March - beginning of April.
- Foliar feeding of potassium permanganate (spraying) is given 2-3 times with an interval of 2-3 days. This is quite enough to compensate for potassium deficiency, as well as protect plants from pests and diseases. The main deadline is the second half of June.
- In mid-spring and autumn (after harvesting), the outer walls of the greenhouse and the soil around it are watered with a 0.5% composition to prevent diseases and pests.
Features of the use of manganese for cucumbers in a greenhouse
Potassium permanganate is used for spraying cucumbers both in open ground and in greenhouses. In this case, the frequency, processing time and dosage are exactly the same. The greenhouse is regularly ventilated, especially in hot weather. When watering or during foliar treatment, humidity increases.
When spraying seedlings, the greenhouse must be ventilated
Potassium permanganate is also used to treat the very premises in which cucumbers are grown. To do this, prepare a concentrated solution of 0.5%, i.e. 50 g (2 tablespoons) per standard 10 liter bucket of water. They need to wipe the outside walls of the greenhouse (pre-wash them from dust with detergent), and also water the soil next to the greenhouse (in a narrow layer to prevent an overdose). The procedure is repeated in spring and autumn.
Precautionary measures
A weak solution of potassium permanganate is not dangerous for humans, plants or animals. However, the crystalline substance and concentrated solutions are a strong oxidizing agent. Therefore, when working with them you must:
- wear gloves;
- do not allow liquid to get into your eyes;
- exclude children's access.
If drops get on your hands, you just need to wash them with warm water and soap. If liquid gets into your eyes, you should immediately rinse them with running water with not very strong pressure.
Potassium permanganate is characterized by high chemical activity. The active substance destroys not only pathogens, but also beneficial bacteria that enrich the soil with nutrients. Therefore, when working, you need to carefully observe the dosage and not water the soil too often.
A few days after irrigation, it is recommended to add bacterial fertilizers to the soil to restore the natural microflora:
- "Phosphobacterin";
- "Azotobacterin";
- "Nitragin" and others.
After applying these products, the soil should “rest” for several weeks. At this time, repeated watering of cucumbers and other plants with potassium permanganate is no longer allowed.
Bacterial fertilizers ensure the growth of beneficial microorganisms in the soil
Conclusion
Watering cucumbers with potassium permanganate is done several times a season. First you need to till the soil before planting seeds for seedlings, then the holes in the garden bed. In June, cucumber leaves are sprayed 2-3 times. The concentration should be small. A solution that has a faint pink color is considered normal.
