Owners of a summer cottage have to solve many different problems. Diseases and pests of cultivated plants cause them the most trouble. It is known for certain that every year they become more and more resistant to classical solutions, so we have to resort to potent agents. One of them is a drug called DNOC.
“Dnok” refers to powerful chemicals for killing pests
Drug safety
Directly opposite reviews are often found about this drug. Some people like the effect they get from it, while others are dissatisfied. Most often, this product is used to treat vineyards and other plants planted on an industrial scale. Treatment, even over an impressive area, is carried out no more than once every three years.
Frequently treating your garden with DNOC can cause illness in both people and plants
The remedy itself is so strong that it is not allowed for free sale. Thus, it is not permitted to use it in a private yard. Despite this, gardeners often resort to using it, observing the permissible interval between treatments, as well as the dose of the drug.
Networks recommend
For those who still dare to use it and want to know how plants are treated with the Dnok fungicide, the instructions should be carefully studied.
· Gardeners recommend covering it with plastic film before processing in order to prevent poisoning of the soil microflora. This will preserve the life of bacteria, microbes, worms and other beneficial inhabitants of the soil, stimulating the formation of humus and increasing the fertility of the soil.
· Some review authors dispute this method, due to the fact that the overwintering place for spores of many fungal diseases is the top layer of soil, and they advise replacing “Dnok” with preparation “B” or iron and copper sulfate.

· Users also mention a new drug - this is the insectoacaracid-fungicide “Brunka”, an analogue of “Dnoka”, which is approved for use on household plots and summer cottages in the CIS countries.
According to reviews, “Dnok” effectively helps against pests and tree diseases. Gardeners talk about how plants were treated using the Dnok product. How to dilute the product? We will definitely consider this, but a little later. In the meantime, let's talk about time and processing methods.
· It is necessary to mix the fungicide and “Preparation No. 30” - the mixture will not be washed off by precipitation for a long time, which is very helpful in the fight against scab and scale insects.
· “Dnok” should be used in the fall after leaf fall.
· It has been noticed that the use of nitrogen compounds when treating plants in the fall reduces their frost resistance. By using the drug in the spring, you can get the effect of abundant fertilizing with nitrogen fertilizers. At the same time, gardeners noticed that all the plant’s energy goes not to fighting pests, but to the development of foliage and shoots. Therefore, users recommend first treating plants with Fufanon or Plus Aktara ash solution. After leaf fall, treat with urea, and postpone the use of “Dnok” and “Preparation No. 30” until spring.
· It is also advised to treat fallen leaves with urea and bury them in trenches one and a half bayonets deep. With the arrival of spring, apply “Dnok” together with “Preparation No. 30”, and urea in the spring of next year.
Composition of DNOC
To obtain the drug, a large number of additional components and catalysts are required. The main ones are:
- ammonium salt;
- dinitroorthocresol.
This video will tell you about the types of spring spraying:
These components are used in a ratio of 60 and 40%, respectively. Ammonium sulfate plays the role of a filler. You should not use this product for treating a small garden. This is a fairly potent substance that makes sense to use in areas of impressive size.
The instructions for using the fungicide drug DNOC state that it has a wide spectrum of action. Its main characteristics:

It does not dissolve well enough in water, therefore, in order to obtain large volumes of the finished liquid, they are increasingly resorting to organic solvents.
Analogs
In the absence of "Dnok", you can use other chemicals that have a similar effect. Each of them must be used in accordance with the attached instructions.
- Clean Garden Nitro.
- Brunka.
- Nitrafen.
- Clean Garden.
Operating principle
The main active ingredient of the drug is 4,6-dinitro-o-cresol. Once applied to the stems and leaves, the solution destroys the fungal infection. It also effectively fights insects, stopping the disease in its infancy.
The main active ingredient of DNOC requires careful handling due to its chemical activity
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.

Reviews
The first thing that should be said about this drug: it is approved for use exclusively in industrial gardens and vineyards. The product is categorically not recommended for use in summer cottages and home viticulture.
The virtual space is teeming with user indignation directed against the owners of specialized sites that advertise the drug and contain information about how plants are treated with the Dnok fungicide. The reviews “appeal” to the conscience of manufacturers and sellers, demand that they refuse to sell the drug, since it is used to poison people, and threaten to contact the prosecutor’s office if there is no response.
According to other users, this tool can be used, but with caution. Some gardeners provide information that they learned from literature describing “Dnok”:
· the use of the product is permitted at a distance of at least 1 km from housing;
· You can use it once every 3 years.
Still others emphasize that the name “Dnok” is not included in the list of drugs for retail sale, and ask what amateur gardeners should do: should they use this product or not?

"Dnok": plant treatment, instructions, reviews
There is another category of users. Many gardeners are loyal to this drug.
They readily argue online that the fungicide “Dnok” is indeed very poisonous; the treatment of plants with the drug should be carried out with great care and exclusively in large farm gardens (formerly state and collective farms), which are located outside the villages.
But it’s no secret that now all kinds of pests and pathogens (scale insects, false scale insects, moniliosis, clasterosporiasis, coccomycosis) have proliferated more than ever. In order to protect trees from diseases, as well as the devastating effects of pests and protect the harvest, it is necessary to use, due to its undeniable effectiveness, the fungicide “Dnok”.
Treatment of plants with this product should be carried out exclusively in industrial gardens. Fortunately, the instructions are always publicly available.
Users admit that the situation with the fungicide is rather ambiguous: on the one hand, everyone understands that it is very poisonous, on the other - what should owners of home gardens do? This poison must be used, at least periodically, by those who have no desire to lose the harvest and the trees themselves.
In general, having honestly warned fellow hobbyists about the danger, gardeners leave everyone to make their own decisions.
Many are ready to share their experience of using the fungicide “Dnok” in private gardens: plant treatment, instructions, reviews are presented in exhaustive quantities.
Users agree on one thing: in some cases, refusal to use the drug can lead to the certain death of the garden. There is no mention of a more effective pest control product in the reviews.
Conclusions and recommendations
1. It is definitely recommended for use both independently and when used together with other insectoacaricides, fungicides, etc.
2. Early spring treatment is carried out once to destroy overwintered pests and clutches of their eggs/larvae, but if necessary, repeated treatment can be carried out in mid-summer when scale insects appear.

Time and method of application
Most often, the fungicide is used in early spring. You should choose the period before buds open, when the temperature is set at +4...+5°C. Experienced gardeners claim that this is the best time for such work: the juices are not yet circulating along the trunk, and most harmful insects continue to hibernate, so they can be easily removed.
The solution affects various insects, including disease carriers. They gather on bushes and trees. DNOC is effective against:
- scale insects;
- ticks;
- copperheads;
- leaf flea.
The drug “DNOC” is extremely effective for long-term protection against a number of pests.
This product is used much less frequently in the fall, since you have to wait until the leaves fall. It is noteworthy that the solution must be prepared in a weak concentration. You can try to spray the plants with the prepared composition no more than once in 3 seasons, but this will do more harm than good.
Preparation of the solution requires care. You can't spill it. You can use this method:
- 50 mg of fungicide is diluted with water in an amount of 1 to 2 liters.
- The finished concentrate is poured into a 10-liter container. Mix vigorously.
- Different crops have their own application rates.
Features of using the product
You can use the drug DNOC for spraying only in special clothing. Work must be carried out wearing gloves, goggles, a gas mask and rubber boots. You can work with the drug for a maximum of 2 hours. Used workwear must be washed and left in a separate room. The preparation of a solution based on DNOC should take place in the open air, away from residential buildings, sources of water and fire.
The drug can be used for 3 years. At the end of its shelf life, the packaging cannot be disposed of in the standard way. It is necessary to hand over the remaining product to a special organization for disposal.
Standards for fruit and berry crops
To prepare a solution for quince, apple and pear trees, use the most saturated solution. Here you need 15 liters of ready-made mixture per 100 sq. m. It should be noted that labor costs for the procedure increase when there are dense thickets of bushes and trees in the immediate vicinity. It is better to protect adjacent areas with film. It will prevent the mixture from seeping into the soil. Due to this, it will be possible to maintain balance in the soil.
If all processing rules are followed, the crop will not be endangered by pests
For apples, pears and quinces, the drug is used to prevent moniliosis, scab and other diseases accompanied by the formation of spots on the leaves. DNOC is effective against leaf rollers and aphids.
If you have to process plums, apricots, peaches and cherries, take no more than 10 liters per area. Thanks to this, it is possible to avoid klyasterosporiosis and moniliosis. The characteristic curliness is eliminated. Scale insects and mites are very sensitive to such solutions.
Currant and gooseberry bushes, which are in the active stage of growth, have a powerful rhizome. They require a dosage of 15 liters per 100 square meters. m. This will get rid of curling and spotting of leaves and the appearance of plaque. A leaf flea attack is unlikely.
Instructions for using DNOC for grapes have their own characteristics. As soon as the warm season arrives, pruning is done to prevent harmful spores and larvae from spreading. After this procedure, immediately spray the drug, without waiting for the sap to run along the branches. Consumption for grapes is 8 liters per 100 sq. m.
The use of DNOC in viticulture eliminates the need to fight mites and lungwort for the whole season. If you carry out this manipulation in early spring, you will be able to avoid rust that affects the foliage in June. Other diseases that the drug can treat include aracnose and septoria.
The main users of the solution are owners of large garden farms. Farmers try to pay maximum attention to safety when working with a strong product.
The benefits of iron sulfate for trees
Iron sulfate is of great benefit to fruit crops, as it enables healthy growth and energy metabolism, helps get rid of parasites and promotes the absorption of micro- and macroelements by the tree. The substance does not have a cumulative effect, so the taste of the fruit will not change.
Note! Iron sulfate is used for all types of garden trees.
Iron sulfate is the most harmless drug
When to spray iron sulfate on fruit trees
This composition is used only before the buds bloom on the trees. It is advisable that the weather outside is cloudy with sufficient humidity. But at the same time, wind and rain should be avoided so that the iron sulfate remains on the plant, having time to have an effect.
How to dilute iron sulfate for treating trees
Iron sulfate helps with many diseases and pests. Depending on what exactly he has to fight, the required dosage is calculated:
- for whitewashing or after pruning, a solution containing 10% ferrous sulfate is made;
- to combat fungal diseases and insects, half a kilogram of the substance must be diluted per 10 liters of water;
- mosses and lichens on trunks can be sprayed with a 30% solution;
- To process grapes in the spring, a weak 0.1% solution of ferrous sulfate is taken every week.
For your information! The substance itself can be purchased at a hardware store. For a garden plot, 3% iron sulfate is well suited.
Precautionary measures
This powerful product has a complex effect and requires careful handling. This applies to both granules and the finished mixture. Yellow granules are not just a source of toxic compounds - they are also explosive. According to the manufacturer's instructions, plantings should be sprayed at a distance of 1 km from pastures and residential buildings. It turns out that the drug is not suitable for a private farmstead. In practice, this rule is ignored by many.
Failure to follow safety precautions may cause health problems
Safety precautions regarding other important points come down to the use of specialized clothing, a respirator, and boots. The head should also be protected; ideally, it is better to wear a gas mask. Recommended:
- Carry out processing in calm weather.
- Avoid contact of liquid with exposed skin and mucous membranes.
- Remove people and pets from the immediate area. It is imperative to notify your dacha neighbors about the planned event.
- When the treatment is completed, do not handle dirty clothes, otherwise skin irritation will occur. It will not be possible to wash off the solution in one go.
After spraying, you must wash the sprayer thoroughly, avoiding draining it into wastewater. Also, after spraying the plants, you should take a shower. DNOC poses the greatest danger to the skin and respiratory tract. It has a significant effect on metabolism, and in some cases can lead to chronic diseases. To do this, it is enough to ingest even a minimal dose of the solution.
The shelf life of the insectofungicide is 3 g. The release date is indicated on the packaging. The bags must be placed in a dry room, away from food and containers for storing them. It is dangerous to keep them near fuels and lubricants. Even diesel and gasoline vapors can lead to unexpected consequences. The price of the interfungicide depends on the manufacturer. A 50 g package can cost 50 rubles or more.
This is interesting: the fungicide Previkur.
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.
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.
Seasonal grape processing scheme for 2020
Grapes are a perennial crop with a powerful root system and flexible trunk. But at the same time, this is a very capricious plant, it is afraid of cold weather and is susceptible to various diseases and pest attacks.
Plants can suffer from the negative effects of viruses, fungi, bacteria and parasites. Factors that provoke weakening of grapes include improper care, external damage and unsuitable climatic conditions. Reduced resistance increases the risk of infection with diseases such as oidium, rot, anthracnose, and mildew. Also, we must not forget about parasites. The most dangerous pests for grapes are mites, leaf rollers, phylloxera, false scale insects, and mealybugs.
