How to spray cucumbers with hydrogen peroxide

An important part of the care of cottagers and gardeners for the care of cucumbers is the prevention and treatment of diseases, pest control. In specialized stores a large assortment of all kinds of chemicals for these purposes. But publicly available and harmless to humans are becoming increasingly popular. So, recently vegetable growers use hydrogen peroxide for spraying cucumbers.

Spraying cucumbers with hydrogen peroxide

It can be watered plants, used to treat seeds, soil. Some people think that this is an excellent top dressing for vegetables.

Features of exposure to hydrogen peroxide

Hydrogen peroxide (hydrogen peroxide) is a colorless substance with a “metallic” flavor that has a natural origin. It is found in precipitation, is a by-product of the oxidation of various substances by air. Contained in mountain air.

The substance has a bactericidal effect due to its chemical properties. It easily reacts with oxidation, for example, with protein compounds, with the release of water. Reacting with other oxidizing agents, it is a reducing agent, the reaction occurs with the release of atomic oxygen. In small concentrations, hydrogen peroxide is unstable and easily decomposes into water and oxygen molecules.

Benefit

How is the beneficial effect of peroxide manifested:

  • due to the oxidizing effect, it destroys the tissues of pathogenic organisms, pests on plants and in the soil;
  • watering promotes aeration of the soil due to the instability of the substance;
  • the quality of tap water improves, as Reacts with organic, pesticides.

In pharmacies, a 3% peroxide solution is sold. It must be stored in a cool dark place. It is important to observe safety precautions, as high concentration oxygen peroxide solutions (30% or more) in contact with human skin and mucous membranes can cause burns.

Indications for spraying cucumbers

Disease Prevention and Treatment

Spraying with hydrogen peroxide has shown its effectiveness as a measure of prevention and control against many diseases of cucumbers, for example, powdery mildew.

If after rains you find white spots of mycelium on the leaf. They merge with each other, forming a white coating that resembles flour flour, and after a while the leaves dry out and the plant dies, which means that cucumbers are affected by powdery mildew. You need to hurry with the processing, because this disease can lead to a loss of 50-70% of the crop.

To prepare the solution, take 1.5-2 tablespoons of 3-% peroxide per 1 liter of water. Leaves need to be processed not only from above, but also from the back.

Growth stimulator

Gardeners indicate the responsiveness of seedlings (especially after diving) and adult plants to spray with the drug. Especially for sluggish, weak seedlings, irrigation with a weakly concentrated solution is recommended: 20 tablespoons per bucket of water. They note that after application, the color of the leaves becomes more intense, the growth rate of green mass increases, cucumbers more actively launch new shoots, the lashes branch better.

Spray stimulates fruiting

There are different opinions about the concentration of the solution for adult plants. For some, some advise diluting 60 ml of peroxide in 3 l of water. Others believe that high concentrations can lead to oxide stress. But small concentrations (0.3 ml per 1 liter of water) are an excellent top dressing: it strengthens the immune system of the plant, stimulates active flowering and fruiting.

Against pests

There is evidence that an aqueous solution of hydrogen peroxide with sugar is an excellent insecticide. Proportions: 100 ml of peroxide and 100 g of sugar are dissolved in 2 liters of water.

Another option for using peroxide against aphids, spider mites is the treatment of plants with an aqueous solution with the addition of a few drops of alcohol and detergent (laundry soap).

Spraying rules

The main rule of the gardener - do no harm. In order for any spraying to bring only benefit, you need to follow a few simple rules:

  • carry out the procedure in the morning or in the evening, as drops of liquid on the plant can produce the effect of a lens, which will lead to a sunburn (cucumbers are especially vulnerable);
  • it is not advisable to do this in windy weather, as the effect will be weak or imperceptible at all;
  • select the correct concentration of the drug, otherwise you can cause a chemical burn of the plant;
  • it is necessary to use personal protective equipment: the body of each person reacts differently to the ingestion of the substances used on the skin and in the respiratory tract.

Vegetable growers are advised to conduct test spraying. Treat a small area with the drug. Soak for 24 hours, if there is no negative effect, you can spray all the beds.

Other uses of peroxide

Hydrogen peroxide can be used for other purposes:

  • soil preparation;
  • seed treatment and stimulation of germination;
  • watering plants.

Preparation of land for sowing seed material for seedlings includes its disinfection. For this purpose, you can use this solution: 4-5 tablespoons per 1 liter of water.

The drug is used to prepare seeds for germination or planting. It is suitable for dressing (used by analogy with potassium permanganate). To get the desired effect, they are placed in a 10% solution for 20 minutes.

The compound can stimulate seed germination. The inhibitors contained in them are known to inhibit germination. To neutralize, the seed is treated with a 1% solution of the substance. Some advise keeping the seeds in this solution for 12 hours. There will be no harm, even if you make the concentration a little more: the substance is not stable, and water is formed as a result of decomposition.

The drug is added to water for irrigation. The effect is considered similar to the action of polarized water. Such a composition will be effective if the roots rot, there is some pathogenic microflora in the soil. Depending on the conditions, you need to water 1-2 times a week.

Practice has shown that when using ready-made soil mixtures purchased in a store, white spots may appear on the soil that are similar to mold. Then you can periodically spray, but watering is not necessary.

Conclusion

The attitude to the use of peroxide in the cultivation of cucumbers, as well as other vegetables and garden plants remains a controversial issue. Some believe that this is "obscurantism." Solutions of the drug do not have attributable properties; top dressing with them can even harm plants.

Others believe that this is a natural stimulant (at low concentrations), an additional source of oxygen. Both sides rely on the chemical properties of the substance. One thing is certain - the bactericidal effect of the drug in rot, the presence of pathogenic microflora.

Practice is the criterion of truth. It is worthwhile to verify with your own eyes the veracity or fallacy of the points of view expressed.
