When can trees be treated with nitrofen. Nitrafen, instructions for use. Spraying the garden in early spring

For the first time, we learned about the treatment of the garden with a drug called Nitrafen (there is also a variant of Nitrofen) from a magazine for gardeners. In it, a colleague in the "workshop" shared his experience of using Nitrofen to spray the garden in the spring. The gardener spoke positively about the drug and gave instructions for use. There was not so much information about Nitrofen on the Internet, and we decided to fill this gap in the article 😉 We hope it will be useful to you and us 😉

Nitrafen: Application in horticulture

It is necessary to spray fruit trees with a solution of Nitrafen before the leaves bloom, early-early in spring (in March-early April). It is enough to process trees and shrubs once. Nitrofen is a very strong chemical agent that successfully:

Destroys pests wintering in the bark of fruit trees;
It has a detrimental effect on ticks, aphids, scale insects, moths, worms, leafworms;
It fights diseases such as septoria, rust, clasterosporosis, coccomycosis, powdery mildew, scab, and other fungal diseases.

Nitrafen in horticulture is also used to disinfect the soil around trees and fallen leaves in the fall. When working with the drug, be sure to observe safety measures.

What is Nitrafen is, as the drug manufacturers indicate: an insecticide, fungicide, herbicide, acaricide, a complex action drug.

Cultures that can be treated with Nitrofen:

fruit trees (apple, pear, cherry)
berry bushes (gooseberries, currants),
strawberries and strawberries.

Instructions for use

Nitrofen for garden spraying (from the review of the "same" gardener)

A solution for spraying fruit trees in the garden is prepared as follows: 300 g of nitrofen is diluted in 10 liters of water. For shrubs, the dosage is different: 200 g of nitrofen per 10 liters of water.

Instructions for use from the label (from the manufacturer of the drug "Nitrafen")

Trees and shrubs in the garden are sprayed with a 3% solution (300 g per 10 liters of water);
Strawberries and strawberries are sprayed with a 2% solution (200 g per 10 liters of water);
The soil under fruit trees and shrubs is also treated with a 2% solution. Solution consumption: 20-30 liters per 100 square meters.

Spraying of the listed crops in the garden is carried out BEFORE buds and leaves bloom!

Safety measures when working with the drug:

The insecticide is poisonous to humans, animals and bees. Before using nitrofen, it is necessary to consider personal protective equipment: respirators, goggles, gloves, closed clothing. After spraying the garden, wash your face and hands thoroughly. Flammable.

Reviews about the drug "Nitrofen" ("Nitrafen")

Among the reviews available on the Web are the following:

It is better to treat the garden with chemistry in early spring, while the trees are sleeping, than to rush around with no less dangerous chemistry when the garden is attacked by pests and diseases.
Cheap drugs are always trying to be removed from the market, for the sake of modern garden chemistry. Reviews against Nitrofen are all the machinations of competitors.
Previously, in early spring, I used a folk method for treating shrubs - spraying with hot water, but the effect was poor. There were much fewer pests after spraying the garden with Nitrafen early in the spring before bud break.

Gardeners who have used the drug on their plots note its positive effect in pest control. Everyone in the families is alive and well, no one was poisoned. After all, if you follow the instructions for use and observe personal protective measures, the use of any chemical agent will be safe.

For early spring garden processing, you can use:

concentrated urea solution,
copper and iron sulphate,
Bordeaux liquid.

We will be glad to hear your feedback on the use of the drug "Nitrofen" (or "Nitrafen") in the garden. Is it worth using the drug or is it better to replace it with other means?

Nitrafen is a 60% dark brown pasty mass obtained by filtering shale phenols with a pungent odor of carbolic acid, which is highly soluble in water.

The product is sold packaged in glass or iron jars, in polymer bottles. The drug is designed to combat plant diseases and harmful insects. The protective effect of Nitrafen complements the stimulating effect on the growth and development of plants.

How does Nitrafen work?

Nitrafen is recommended to be used in early spring, until the buds swell, or in late autumn, when the leaves have fallen. The substance has a pronounced fungicidal, insecticidal and herbicidal action. Nitrafen provides fruit bearing trees and crops with long lasting protection, keeping well after spraying on all soils and organic surfaces.

When penetrating into the soil, Nitrafen has a non-selective effect, significantly inhibiting the growth of weeds. As a herbicide in private households, the drug is not used because of the unstable soil salinization it creates.

Instructions for use in horticulture

On fruit trees, Nitrafen is used against lichens, mosses, scab, leaf spots of various origins.

The drug effectively destroys sucking-gnawing pests: caterpillars, ticks, moths, suckers, scale insects, aphids, winter moths, leafworms and others. The working solution is prepared from 200 grams of the drug and 10 liters of water. A solution of this concentration is also treated with wounds formed on fruit trees.

For general spraying of the garden in order to destroy the infection, the soil of the near-stem circles of fruit trees, under the bushes and around the berries, is sprayed with a working solution of 300 grams of Nitrafen per 10 liters of water. Before this, it is necessary to collect and burn all the crumbled foliage. To spray 1 adult tree and the soil under it, 10 to 30 liters of solution will be required.

On berry bushes (raspberries, currants, gooseberries), the drug is used against powdery mildew, scab, septoria, anthracnose, to control aphids and other pests. To prepare a working solution, 150 grams of Nitrafen is diluted in 10 liters of water. After the leaves fall, the bushes and the soil under them are cultivated. For 10 m2 of plantations, 1.5-2 liters of solution is enough.

On grapes, Nitrafen is used to combat mites, aphids, scale insects, moths, when infected with anthracnose, mildew, iodium. The entire surface of the grapes, soil and vegetation under the bush is treated with a solution of 200 grams of Nitrafen per 10 liters of water. The drug has a burning effect on young greens, so all work is recommended to be done in the spring, until the leaves have blossomed, or in the fall, when the green mass falls off.

On strawberries, nitrafen is used against gray rot of berries and leaf spot. To prepare the solution, take 150 grams of the drug per 10 liters of water. For spraying 10 square meters of strawberry plantations, 1.5-2 liters of solution will be required. The processing of strawberry bushes and the soil under them is carried out in the spring, until the leaves begin to grow. The air temperature should not be below 4°C. Only one treatment is allowed.

Nitrafen effectively fights weeds: colza, wood lice and others. The soil must be cultivated in early spring, dissolving 300 grams of the drug in 10 liters of water.

Precautionary measures

Early spring and late autumn use is a safe way to use Nitrafen, proven in practice. The drug can be attributed to the preventive, rather than symptomatic weapon of gardeners for multi-purpose support of plots. It is recommended to spray allotments in light winds, in dry weather, choosing evening or morning hours.

Working with Nitrafen requires caution and compliance with all personal safety measures. This drug in its pure form is poisonous, can cause irritation of the respiratory tract, skin, mucous membranes of the eyes.

Prolonged contact with the product can lead to the development of severe dermatitis. When preparing a working solution, it is forbidden to exceed the concentrations of the substance recommended by the manufacturer. It is not recommended to use Nitrafen more than once every 3 years. During pregnancy, the drug should not be used.

Nitrafen remains in the soil for a long time (with autumn preventive spraying throughout the winter), therefore, it is currently not used so actively. The chemical resistance of the agent was considered an advantage in the Soviet years, when Nitrafen was massively used in crop complexes.

Nitrafen's analogs

Instead of Nitrafen in gardens before bud break, you can use its analogues:

Oleocuprite is a drug consisting of petroleum oil and copper naphthenate to combat the eggs of mites, suckers, aphids, as well as against various spots and scabs; for spraying fruit trees and berry bushes, a solution of 400 grams of the drug in 10 liters of water is used.
Copper sulfate - effective against pathogens of scab, clasterosporiasis, anthracnose, septoria, various spots, a working solution of 1% concentration is used: 100 grams per 10 liters of water.
Ferrous vitriol - a working solution of 2-3% concentration (200-300 grams per 10 liters of water) is used before the start of the growing season for spraying fruit trees and the soil under them; effective against lichens and mosses, inhibits the development of spotting, scab, moniliosis, fights against diseases of stems and uterine branches.

In order to grow not only a qualitative, but also a quantitative crop, gardening enthusiasts not only need to create favorable conditions for the growth and development of fruit and berry crops, but also take care of their protection from harmful insects and various kinds of diseases. With the right and timely, it is possible to increase the level of plant resistance to viruses, bacteria and other pathogenic microorganisms, and increase the chances of collecting tasty and beautiful fruits.

Appointment of the drug Nitrafen

Due to the sodium salt content of alkylphenol nitration products obtained from coal or shale semi-coking tar, Nitrofen is actively used to protect the garden from fungal and mold diseases, which ensures their normal development and effective fruiting. In most cases, the insectofungicide is used as an aqueous solution, which is used to treat fruit and berry crops along the leaf.

The paste-like mass of 60% obtained by filtering shale phenols is distinguished by a dark brown color and a pronounced pungent odor of carbolic acid. Its advantage is good solubility in water. You can buy an agrochemical at any specialized outlet, where it is presented in glass, iron containers, as well as in polymer containers. In addition to the protective effect, Nitrafen has a stimulating effect on the growth and development of horticultural crops.

The principle of action of Nitrafen

According to the instructions for use, Nitrafen should be used at the beginning of the spring season - before the activation of vegetation processes. Such measures will make it possible to destroy harmful insects that have successfully overwintered in the shoots and bark of trees. And autumn treatments with this insectofungicide will effectively prepare the plants for the dormant period, they are produced after the leaves have completely fallen off.

The main action of Nitrafen is to destroy harmful insects and pathogens. The drug is positioned exclusively on the positive side, it stands out with fungicidal, herbicidal and insecticidal effects. The agrochemical is able to create reliable and long-term protection for fruit-bearing crops, this is achieved due to its long-term preservation on any type of soil and organic surfaces after spraying.

Once in the soil, Nitrofen begins to show its indiscriminate effect, effectively restraining the growth processes of weeds. It is not worth using as a separate drug as a chemical for weed control, since the effect it creates does not differ in long-term action and salts the soil.

How to treat with Nitrafen

The chemical preparation shows its high activity against:

lichens;
fungal infections;
mosses;
various kinds of spots on leaf plates.

ticks;
caterpillars;
mole;
scale insects;
suckers;
small aphid colonies;
winter drops;
leaflets, etc.

To prepare the liquid, 200 g of Nitrafen and 10 liters of water are used. In this ratio, a solution is prepared for the treatment of wounds formed, various kinds of damage to fruit and berry crops.

To disinfect the soil, the Nitrafen preparation is applied to the near-stem circles of garden plantings, which makes it possible to effectively deal with pathogenic microorganisms, which significantly reduce yields and destroy plants. To destroy the infection in the soil, it is necessary to dissolve the agrochemical in water at the rate of 300 g per 10 liters of water. But before performing the manipulation, you should collect the fallen leaves and burn them at the stake. To process one adult planting, you need 10-30 liters of working fluid.

To prepare a working fluid, you need to dilute 150 g of the product in 10 liters of clean water. The procedure is performed after the leaf mass has fallen off. Not only the above-ground part of the plants should be sprayed, the soil also needs to be shed with a solution. The consumption of the liquid used per 10 sq.m. is 1.5-2 liters.

Grape bushes in the event of adverse weather conditions and in violation of agricultural practices also suffer from the invasion of harmful insects and various kinds of pathogens. Especially, plants are often affected by fungal infections. To process the grape bush and the soil under it, the agrochemical is diluted at the rate of 200 g per 10 liters of water.

But here you need to know one nuance: the effect of the drug adversely affects the tender young greenery, it burns it, which is completely unacceptable. Based on these considerations, it is recommended to use a working solution based on it only at the beginning of the spring season, until the leaves have yet blossomed, or, in the autumn, after the foliage has fallen.

Strawberries are also no exception, and are subject to various diseases, attack by harmful insects. Nitrafen is effective against gray rot and leaf spot. Chemical treatments should be started after the first suspicions of a fungal infection are identified.

In order for the product to maximize its effectiveness, it is necessary to properly prepare the working fluid: 150 g per 10 liters of water. For processing strawberry plantations with an area of 10 sq.m. you will need 1.5-2 liters of working solution. Spraying of landings and the ground under them is also carried out at the beginning of the spring season, before the formation of new leaf blades. The air temperature on the day of processing should be at around 4 degrees. The optimal number of procedures is 1 time.

Experienced gardeners and gardeners often use this chemical agent against weeds such as colza, wood lice. Disinfection of soil in the garden, in particular, in tree trunks, is recommended to be carried out in early spring with a solution that is prepared at the rate of 300 g of the drug per 10 liters of water.

Advantages and disadvantages of Nitrafen

Among the positive characteristics of insectofungicide can be noted:

creation of a reliable barrier against harmful insects and various diseases;
wide range of influence;
high performance indicators;
reduction of growth processes in weeds;
economical consumption;
ease of use;
relatively low cost.

Despite a whole list of advantages, the agrochemical has its drawbacks:

soil accumulation and salinization.

But such negative consequences can be in the case of frequent and underdose use of the drug.

What precautions should be taken

In order to avoid causing serious damage to garden plantings, early spring and late autumn activities should be carried out using Nitrafen. The treatments carried out during these periods are absolutely safe for plants. With the help of this chemical agent, it is possible to carry out not only therapeutic manipulations, but also preventive ones. The best time to spray garden plantings is dry weather, as long as there is no strong wind. The optimal time of day is evening and morning hours.

Given the fact that the drug is a chemical agent, when using it, one should be extremely careful and not neglect personal safety measures. Since in its pure form it is a very toxic substance that can instantly provoke irritation on the skin, mucous membranes of the eyes, and respiratory organs.

If you contact this drug for too long, then there is a high probability of developing severe dermatitis. It is necessary to prepare the working fluid only in accordance with the manufacturer's instructions, without exceeding the permissible dosage. In addition, it is not recommended to use the garden treatment more than once every three years. A special restriction applies to pregnant women, they are prohibited from working with agrochemicals.

Nitrafen has a long duration of action, it remains in the ground throughout the winter season. Therefore, it is so effective to carry out preventive autumn activities.

Nitrafen's analogs

You can replace this agrochemical when processing garden plantings:

Oleocuprite. The drug is made on the basis of petroleum oil and copper naphthenate, which is effective against eggs of mites, aphids, suckers, scab, and various kinds of spotting. Make a solution at the rate of 400 g per 10 liters of water.
Copper vitriol. With a working liquid prepared from 100 g of the product and 10 liters of water, it is good to fight against fungal infections, septoria, spotting.

The drug Nitrafen is a fairly strong remedy that can destroy pests and various infections. With it, you can protect garden plantings, but if the dosage is exceeded, it can also cause harm. Therefore, it should be bred according to the instructions.

Kira Stoletova

Nitrofen is a drug of complex action and at the same time an insecticide, fungicide and acaricide. It is advised to use the drug in early spring even before biological awakening and in the autumn period against pests and pathologies. The optimal rate is 200-300 g per 10 liters of water. Nitrofen and grapes interact well.

Indications for use

The diseases for which Nitrofen is used are very diverse, therefore, the instructions for use cover several problems at once.

Fruit trees can be exposed to various kinds of pests and diseases, which are best eliminated with Nitrofen. These include mites, aphids, leaf spot, scab, etc.

The effectiveness of the drug in the fight against weeds should not be underestimated. The soil can be treated with Nitrofen during early spring.

The action of the chemical

After spraying, the chemical remains in sufficient quantity on absolutely any surface, protects cultivated plants (especially different grape varieties) and trees that are already bearing fruit for a long time.

After penetration into the soil, Nitrofen inhibits the growth of weeds for a long time, but it is not used as a herbicide purposefully in private lands, because. capable of creating unstable soil salinization.

Composition and form of release

The drug is a product of the process of nitration of phenols of coal origin and is a dark brown mass, similar in consistency to a paste with the smell of hydroxybenzene. The composition of the substance includes nitration products of alkylphenols (64-74%), water (26-36%), OP-7 or OP-10 (up to 3%). Nitrofen is highly soluble in water, hydroxides, benzene, ethers.

Due to its chemical properties, when it comes into contact with the skin and mucous membranes, it causes local irritation and burns, followed by adverse symptoms.

Rules for the use of the drug

To make a working solution, you need 200 g of Nitrofen, which are dissolved in 10 liters of water. For soil disinfection, 300 g is taken per 9 liters of water. For 1 adult plant from 10 to 30 liters of water. For each type, the instruction provides for a different dose.

Berry bushes. To prepare a solution for spraying, about 150 g of the drug is diluted in 10 liters of water, and the bushes and soil are processed after the leaves fall off. This 3% solution for grapes is used in the amount of 2-2.5 liters per 10 m².
For strawberries, a 2% solution is used: dissolve 200 g of the drug in 10 liters of water.
Weeds: 300 g of the drug per 10 liters of water.

Safety

The tool is used to combat harmful insects and various diseases that can adversely affect the crop and the growth and development of the crop. The drug is especially dangerous for humans and animals, so it is important to take precautions.

It is better to move pesticides in hermetically sealed containers. Before spraying, familiarize yourself with the composition, find out the consumption rate, degree of toxicity, shelf life, etc.

As you know, for the effective fruiting of trees, it is necessary to provide them with proper care. In particular, it is necessary to spray the garden in early spring and autumn, and in some cases in summer. In this article, we will consider the purposes for which spraying is performed, what preparations are used for this, and how this process occurs.

Spray seasons

It is impossible to accurately name the timing of spraying, as they depend on the following factors:

The climate zone in which the garden is located.
Vegetative processes of trees.

Early spring spraying is carried out immediately after the plants wake up from winter sleep. The last spraying is carried out in the fall after leaf fall. Next, consider the features of spraying at different times.

Note!
Spraying can only be done in calm weather.

First half of spring

To protect plants from pests and diseases, they are sprayed before the activation of vegetation processes, i. at the beginning of the spring. Proper selection of fungicides will get rid of most of the pests that could successfully overwinter in tree shoots or bark.

In addition, this procedure will become a reliable prevention against various diseases. Spraying garden trees before bud break is carried out with copper sulfate or Bordeaux liquid.

These drugs serve as prevention against a number of diseases:

scab;
Moniliosa;
Spotting;
coccomycosis;
Clasteriosporiosis, etc.

In addition, these fungicides kill hatching larvae from eggs laid by insect pests. Some types of trees can also be sprinkled with iron vitriol, as it performs the same functions as copper sulfate, but also saturates the plants with iron.

In particular, this element is especially important for normal development and growth, which, in addition to the apple tree itself, includes the following plants:

Pear;
Hawthorn;
Rowan;
Iva etc.

Spraying garden plants during this period is carried out twice:

"Along the green cone" - before the flowers begin to bloom (unopened buds resemble cones). Usually, this procedure is the prevention of diseases such as powdery mildew and spotting.
As a rule, the trees are sprayed a second time in the spring with urea, during the so-called "bud isolation". This allows you to kill the larvae of most insects.

The next spraying is done after the plants have faded.

Advice!
Often, instead of urea, nitrofen is used to spray the garden.
This drug is also very effective in controlling insect pests and certain types of diseases.

second half of spring

After all the flower petals have fallen, it is necessary to perform the final spring spraying. Moreover, the drug is selected depending on the type of tree:

Wood	Preparations
Pear and apple tree	Preparations against scab and other spotty diseases are used, for example, you can use: Vectru; Rubigan; Impact; Speed, etc.
Apricot	To prevent monilial burns or perforated spotting, trees should be treated with Bordeaux mixture or blue vitriol.
Peach	The greatest danger is clasterosporiasis, leaf curl and codling moth caterpillars. Therefore, plants should be treated with copper-based fungicides, as well as insecticides such as Stefesin or Decis.
Plum	As a rule, caterpillars of the codling moth, as well as aphids and mites, bring lesions. In addition, polystigmosis and moniliosis are common diseases. Therefore, the following poisons can be selected for spraying: Zolon; Dandim; Fufanon.
Sweet cherry and cherry	Such plants are affected by coccomycosis and clasterosporiasis, as well as some pests. Therefore, the treatment can be performed with the following active substances: Copper chloride with the addition of poisons; Topsin.

Note!
It is necessary to spray the entire garden, and not individual types of trees.

In addition, to prevent fungal diseases and tick infestation, gardens are sprayed with carbamide or a solution of DDT powder.

Summer

In summer, as a rule, do-it-yourself gardening is done with urea. This fungicide not only kills many insects, but also saturates the trees with nitrogen. The procedure in the hot season is carried out several times.

The treatment of young plants is usually performed with folk remedies, as they are completely safe. For example, against aphids use tobacco tincture or other strong-smelling liquid.

Autumn

In autumn, trees are sprayed twice:

At the beginning of autumn - urea;
After leaf fall - with special preparations that prevent putrefactive processes.

I must say that it is not necessary to purchase preparations for the second spraying, since you can make them at home.

The instruction looks like this:

300 grams of copper sulfate must be dissolved in three liters of water;
Then 400g of fluffy lime should be mixed with 10 liters of water;
While stirring the lime mortar, a solution of copper sulfate should be poured into it in a thin stream.
The resulting composition must be filtered through gauze folded several times.

Note!
Regardless of which preparation will be used to spray the garden, this procedure must be performed in dry weather.

This solution has a soft blue color and will stain the trees for a while, however, the paint will wash off over time. The price of such a drug will be significantly lower than the purchased product, and the effectiveness is the same.

Spray technology

The spraying process itself is quite simple, however, requiring patience and the presence of the following:

Special piston-type pump for processing trees or compressor;
Respiratory mask;
Rubber gloves;
Glasses;
Substances for the treatment of trees.

In the photo - a respirator for respiratory protection

Spray technology is as follows:

If the procedure is performed in the spring, it is necessary to treat the tree trunk with a stiff brush to remove moss or lichen. This procedure will lead to the activation of cells and the growth of shoots.
Shake the solution well before use. This procedure must be repeated periodically during the spraying process.
Then, using a compressor or pump, spray the fungicide evenly onto the tree. It is necessary to process all parts of the plant, in particular, the leaves are sprayed from both sides. At the same time, it is necessary to ensure that the preparations lie down with uniform dew, for this the tip of the tool must be kept at a distance of about 80 centimeters from the leaves.
After completion of work it is necessary to wash the device. Protective elements (goggles, gloves and respirator) must not be removed.
