Additional ingredients include sodium and ammonium sulfate. Thanks to this, the effectiveness of “Dnok” increases, and the active component is evenly distributed in the product.
Operating principle
When spraying plants, the fungicide “Dnok” inhibits the development of fungal spores and prevents their reproduction. And since the product also has acaricidal-insecticidal properties, it also destroys larvae and adults of wintering pest species. The maximum concentration of the active substance in plant tissues is recorded 48 hours after treating the garden with “Dnok”. You can clearly see the positive result 4 days after spraying the foliage.
Important! It is recommended to treat with this fungicide no more than once every 3 years.
What diseases and pests are they used for?

After spraying, you can observe the effect after three days. Direct introduction of infectious agents into spores occurs in the first two days. During this time, the source of infection can be neutralized, and subsequently it is completely eliminated. The lasting effect lasts for another month.
Instructions for use of the drug Dnok
In accordance with the instructions, “Dnok” (double blow) must be used during certain periods of the year. And also when preparing the fungicide solution, strictly adhere to the dosage.
When is the best time to treat with Dnok?
Spraying with “Dnokom” should be done in early spring and late autumn. In the first case, it is necessary to carry out treatment until the buds appear. Therefore, when the temperature reaches above zero, not lower than +4 degrees, a fungicide should be used. It is important to have time to carry out the treatment before the sap begins to flow, since it is at this time that the product shows maximum effectiveness.
Important! During spring treatment, it is impossible for the “Dnok” solution to flow onto the soil, so you need to cover the root circle with a film or tarpaulin in advance.
In the second case, the fungicide should be used after leaf fall and after all work with the soil under bushes or trees is completed, but the air temperature should not be higher than +5 degrees.
Application of "Dnoka" in the fall involves spraying the branches, trunk and top layer of soil with fallen leaves. For this treatment, it is recommended to use a 0.5-1% fungicide solution. At low air temperatures, the active component of “Dnoka” penetrates the soil to a depth of 7 cm and thus destroys pathogens and pests that overwinter not only on the plant, but also in the top layer of soil.
Important! When applying “Dnok” in autumn, the root circle should not be covered, since during this period the fungicide is not able to affect the fertility of the soil.
Preparation of the solution
To prepare the Dnoka working solution, you must initially pour 500 ml of warm water into a separate container, and then add 50-100 g of the drug powder to it, stir thoroughly. Then increase the volume of liquid to 10 liters.
The drug is poorly soluble in cold water
Rules for using Dnok
Depending on the type of crop, the fungicide needs to be used differently. If used in spring, the concentration of the active component should not exceed 4%, which is achieved by dissolving 400 g of powder in 10 liters of water. And during autumn treatment with “Dnokom” – no more than 1% based on 100 g of product per bucket of water.

Reviews from gardeners
Elena
I'm still new to gardening. Not knowing how to treat the garden against diseases and harmful insects, I turned to the seller in a specialized store. He immediately recommended DNOC to me. He said that it is now the most popular, the most useful and effective. I paid only 50 rubles. per pack. True, I did not read the information on the packaging in full. I learned about the precautions when I came home. It turns out that they only use it on farmland. Its sale to private individuals is prohibited. I was surprised. To be honest, I never decided to use it.
Valery
I really respect this drug. If used correctly, it improves tree growth and kills all pests that grow in the tree trunk. This is a fungicide and insecticide in one bottle. As a former agronomist, I recommend spraying garden crops once every 4 years after the leaves fall. But I warn you that you need to use it with caution, because it is harmful. God forbid it gets on your skin and then you can’t wash it off.
Olga
The drug is very strong! I only use it on mature trees. Neither shrubs nor young trees should be treated with it. You can try to choose the proportions of the solution, but burns may occur. DNOC is very poisonous, and inhaling its vapors is especially dangerous. Trees are treated until mature buds form.
Storage rules
The fungicide can be stored only if the integrity of the packaging is maintained. The shelf life of the powder is 3 years from the date of production. The product should be stored in a dark, dry place out of reach of children.
Dnoka powder is explosive, so do not place the product near containers with flammable liquids.
How long can diluted Dnok be stored?
The shelf life of the prepared Dnoka solution does not exceed 2 hours. Therefore, the product must be used immediately after preparation. In this case, it is necessary to clearly calculate the required amount of the drug for processing, since it is impractical to prepare it for future use.
Important! During disposal, do not allow any remaining working solution to enter a body of water or running water.
