Iron vitriol: application in gardening in the spring. How to use iron sulfate in gardening Iron sulfate from what helps in the garden

To plants on personal plot grown healthy and gave a regular harvest, it is necessary to carry out their regular processing. One of the simplest and available funds used for this purpose is iron sulfate.

Below we will consider its purpose and features, as well as its application in horticulture and viticulture.

This is iron sulfate, obtained as a result of the reaction of the interaction of ferrous iron and sulfuric acid. The crystals have a bluish-green tint, which distinguishes the drug from copper sulphate, which has a pronounced blue color.

The fungicide is highly soluble in water and in this form is used for spraying plants. For various kinds processing, different concentrations of the drug are used.

Should know! The drug is a contact fungicide. That is, it does not penetrate into the intercellular structure of plants and does not accumulate in them. Therefore, it does not cause any harm to humans.

Purpose of iron sulphate

On the garden plots iron sulphate is used for the following purposes:

For the treatment of fungal diseases of shrubs and trees: scab, coccomycosis, powdery mildew, clusterosporiosis, etc.
For the treatment of grape bushes from anthracnose, gray rot, oidium.
For disinfection of cuts and wounds on tree branches.
To combat spotting on roses.
As a remedy for the elimination of mosses and lichens.
For the destruction of harmful insects.
As a means for processing vegetable stores, cellars, ground floors, wooden structures to get rid of mold and mildew.
Like fertilizer in the garden.

Instructions for use

Let's bring brief instructions on the practical use of iron sulphate for the treatment of plants, as well as for use in everyday life.

How to dilute the drug?

To provide proper quality solution, it is necessary to prepare it correctly.

Pay attention to the following nuances:

The container in which technical vitriol will be bred must be either glass or plastic. It is not allowed to prepare the solution in a metal container.
The cleanliness of the container must be ensured. If the container previously contained some Chemical substance, it is difficult to predict the reaction of ferrous sulfate with the remains of this substance.
Stir the solution should be carefully, slowly. After mixing it initially, it is better to let the solution brew a little, and then mix it again. In this case, more ferrous sulfate will pass into the water.

Consider the schemes for the use of ferrous sulfate in relation to specific situations:

Against pests

inkstone actively exhibits its insecticidal properties in the fight against crawling pests and their larvae. For this purpose, trees are sprayed in the spring, before bud break.

Also, near-stem circles are processed. For spraying use a solution at a concentration of 5%. That is, it is necessary to pour 500 g of sulfate into a bucket of 10 liters. Processing is carried out 2 times a year: in autumn, after leaf fall, and also in spring, while the buds have not yet woken up.

Important! Keep in mind that young trees have thinner bark. It is enough to process them only 1 time, in the spring.

Moss and lichen control

Often, the garden suffers from the presence of lichens and mosses on the trees. Especially often they form on old trees and bushes, as a result of which the latter dry out and disappear.

Iron vitriol perfectly copes with this problem. Shrubs and stone fruit trees are treated with a solution with a concentration of 3% sulfate. pome trees require increased concentration drug - 5%.

Spraying of trees and bushes is done twice, with a break between approaches of 2 weeks, in autumn or spring. After double treatment, lichens and mosses fall off the branches.

Also, you can prepare a special whitewash composition, which covers the affected areas. To do this, take an extract from the ash and add 5% vitriol.

Whitewash the damaged branches with this composition. Ash extract is prepared in the following way. 1 cup of sifted ash is poured with 3 liters of boiling water and infused for 3 days. Then the volume is brought to 10 liters.

Treatment of fungal diseases

For the treatment of plants from fungi, iron sulfate can be very useful. But the concentration of the drug is applied no more than 3%.

A solution for plants is prepared at the rate of 10 liters of water and 300 g of ferrous sulfate. Processing is carried out 2-3 times, with a break of 7 days.

against chlorosis

The symptoms of chlorosis are pale leaves plants, poorly developing shoots, underdeveloped fruits. Apples, plums and cherries are especially susceptible to this disease.

This disease occurs when there is a lack of iron in the soil. Iron vitriol allows you to quickly make up for the lack of iron. To do this, it is recommended to use a spraying of plants with a low concentration preparation so as not to get burns on the leaves.

50 g of vitriol is added to 10 liters of water. Processing of plants is carried out several times, every 5-6 days. A sign of cure is the return of the leaves to their normal green color.

If chlorosis annoys regularly, then preventive treatments with sulfate can be carried out by reducing the concentration of the fungicide to 10 g per 10 liters of water. Prevention is sufficient to carry out weekly.

Spraying the vine

Grapes largely need iron intake. For this ideal option is iron sulphate. It can be used in two versions: spraying and root dressing.

Foliar processing

It is recommended to process vine a solution of ferrous sulfate of various concentrations, which depends on the season and the type of grape disease:

In early spring, a week after removing the shelter from the vine, the instruction prescribes the use of a solution of 0.5-1%.
For the treatment of chlorosis, a 0.05% solution is used.
To get rid of oidium, mildew, spots and pests, a solution of 4-5% is prepared (on a bare vine).
Autumn processing before shelter for the winter involves spraying the vine with vitriol at a dosage of 3-5%.

Please note that a lower concentration of the drug is applied in the spring.

Should know! Treatment of the vine with ferrous sulfate in early spring delays bud break by about a week, which allows the grapes to avoid damage to young sprouts as a result of spring frosts.

Root top dressing

In addition to spraying, iron sulphate is also used for application under grape bushes. It is best to combine this process with watering. If the vine gives little growth, the leaves are pale, and the clusters ripen late or do not have time to ripen at all, then the grapes are clearly lacking in iron.

Alkaline soils are especially poor in iron. If you notice these signs in your vines, add some ferrous sulfate to your water to irrigate. It is not necessary to dilute a lot of vitriol in water. It is enough to add 10-15 g of the drug to 10 liters of water.

Processing of grape seedlings

Experienced growers have found effective method improving the rooting of the vine. They treat the upper parts of the stems or young seedlings with a weak (0.5%) solution of iron sulfate.

This delays the budding, while accelerated root formation takes place in the lower part of the seedling. Such plants grow stronger and more viable.

Spraying berry bushes and trees

In the spring, before the start of the growing season, and also in the fall, after leaf fall, the plants are treated with a solution of vitriol at a concentration of 3%.

Processing currants, gooseberries, felt cherry, as well as other shrubs and trees along a green cone is allowed, but the concentration of the solution should be 0.1-1%.

Such a solution is safe for leaves and young shoots. At higher concentrations, foxes and shoots can get burned.

Treatment of cuts and wounds on tree branches

Infectious agents often get on open wounds and cuts of trees, provoking damage to the wood. Infection can lead to serious tree disease and even death.

By treating the wounds with iron sulphate, we get rid of the infections already there and prevent new infections of the trees. For processing, a concentrated solution of vitriol should be prepared. For 10 water you need to put 100 g of ferrous sulfate. Damage is treated with this solution.

Application as a fertilizer

Iron, which is part of the drug, is in it in a readily soluble form, so it can be easily absorbed by plants.

Feeding is done in two ways:

Root. Vitriol is brought in for digging, pre-mixing it with compost. For 10 kg of compost take 100 g of ferrous sulfate.
Foliar. 5-10 g of vitriol is dissolved in 10 liters of water, after which it is sprayed with a solution of the plant. Tomatoes, cabbage and other garden crops respond well to such top dressing.

Not everyone knows that iron sulfate can be made independently high effective fertilizer- chelate. Its value lies in the fact that it stimulates photosynthesis in plants.

The cost of the finished product is unusually high. Making it yourself will cost a hundred times cheaper. The recipe for the chelate is as follows:

3 liters of water are boiled (to soften), cooled, and then 1 tablespoon is diluted in it citric acid. Add 2 teaspoons of ferrous sulfate to the solution.

The resulting fertilizer acquires a light orange color. The ready-made solution should be used within 1-2 hours after preparation, so it should be prepared immediately before use. Plants are sprayed with chelate or applied under the roots. Apply several times during the season.

Processing cellars and vegetable stores

Iron vitriol effectively resists putrefactive processes and mold.

This happens due to the fact that the solution forms a film on the treated surface that deprives the fungi of oxygen. In such an environment, pathogenic microflora is not viable.

The walls of cellars, vegetable stores, wooden fences beds, wooden gazebos, greenhouses and other structures on the site.

Main disadvantages

Despite a lot of positive properties, this fungicide has several disadvantages, which are extremely important for a gardener to know about:

The drug is rapidly oxidized in air, losing its useful qualities. It retains its effectiveness after application for 10-14 days.
Ferrous sulfate is hygroscopic. It is easily saturated with moisture, so it should be stored in a tightly closed container.
The concentration of the drug is less than 1% is considered ineffective for the treatment of plants.
At a concentration of more than 1%, the drug can leave burns on green leaves and shoots due to strong acidity, so spraying is done only after leaf fall or in early spring, before bud break.
A solution of ferrous sulfate will not help in the fight against diseases caused by bacteria.

Compatibility with other drugs

It should be borne in mind that ferrous sulfate should not be mixed for spraying with organophosphorus preparations, which are usually used to kill plant pests.

For example, with karbofos, popular in the past. In addition, it is unacceptable to mix it with lime and substances that actively dissolve in alkaline solutions.

Precautionary measures

So that iron vitriol does not harm the gardener, you should follow certain safety rules when working with the drug:

Spraying in the garden is best done with protective gloves and a respirator. Although this substance is not a poison, it is better to protect yourself from getting the fungicide in the respiratory tract and on the skin.
In case of accidental contact with vitriol in the eyes or on the skin, it is necessary to immediately wash it off with water.

The experience of gardeners proves that, with proper and timely use, iron sulphate can provide effective assistance in the treatment of plants and be a reliable supplier of iron for them.

Inkstone - chemical formula which is written FeSO 4 , is a powdery mixture of small bluish-green crystals. Other names for this substance are ferrous sulfate and ferrous sulfate. The share of active active substance in it is about 53%.

Ferrous sulfate or iron sulphate

Ferrous vitriol is a relatively inexpensive microfertilizer, which can be found in almost all self-respecting gardening stores.

It differs in properties, although in many respects it has similar qualities as the more famous, blue vitriol. There is a misconception that it should be used against fungal diseases of shrubs and trees, but this is not the case. Iron sulphate is used as a microfertilizer to replenish the reserves of iron absorbed by plants in the soil. There are also derivatives, such as iron chelate (ferrous iron).

Almost all fruit trees and grape bushes often suffer from a lack of this microelement. Our task, as summer residents, is to feed necessary quantity these plantings.

Foliar top dressing with iron sulphate

Foliar top dressing should be carried out once a year, during early spring. by spraying, they treat the trunks and branches of trees before the beginning of the landscaping phase with foliage. Late processing adversely affects the young leaves of plants.

Recommended doses of the drug: 0.5-1% solution of ferrous sulfate (that is, 50-100 grams per 10 liters of water). For plants with thin bark (young seedlings of trees, pears), the smallest dose of the drug should be done - 50 grams per 10 liters of water. For adult treatment fruit trees use a more saturated solution at the rate of 100 grams per 10 liters of water.

Fertilize the soil with iron sulfate by introducing it into the ground for autumn or spring digging (at the rate of 100 grams per 1 m2).

Iron sulphate for frost protection

Experienced gardeners and viticulturists use this preparation in regions prone to frequent return frost. The buds of plants treated with iron sulphate bloom later for 2 weeks, which makes the shrubs more protected from the influence of adverse weather conditions.

Iron sulfate for pest control

Spraying against pests is carried out 2 times. During the growing season, only a 1% solution of vitriol can be used, and after the leaves are shed by shrubs, 5% will already fall off.

Iron vitriol in viticulture

In viticulture, it is used against such dangerous diseases as spotted necrosis, bacterial cancer, anthracnose and other diseases. The vine is treated with a 5% solution, in the spring, and then in late autumn. Subsequent processing is done after 2 weeks. Higher concentrations can burn leaves and green shoots.

A number of winegrowers treat cuttings with a weak solution of ferrous sulfate when propagating grapes. The tightening film does not allow the buds to open for a short time, while during this time callus is formed on the lower sections of the cuttings and small roots appear, which increases the better development of the seedling.

Iron vitriol against house fungus

And although this drug is used less frequently than copper sulfate, it also has a fungicidal effect. To get rid of the house fungus, it is necessary to dilute 1.5 kg of iron sulfate in 10 liters of water. The walls of basements and vegetable stores are covered with such a solution, created at the rate of 60 grams of the drug per 1 liter of water.

Iron chelate against chlorosis

Chlorosis is a common plant disease that occurs due to a lack of sun rays and torrential rains. It especially occurs when the plant is grown on sandy soils.

A disease such as chlorosis can be caused by an infection (viruses, fungi) or by a non-infectious way, for example, a lack of trace elements in the soil.

The disease first affects the center of the rosette, and then affects the young leaves. They just suddenly stop growing and turn more and more yellow, turn white. It happens mostly in flowers. Another "yellowing" of the foliage is from excessive watering. The roots simply suffocate from the dense earth. In the fight against chlorosis, the so-called iron chelate is used. But it costs a lot, and it’s hard to find it on sale.

When signs of chlorosis appear with a solution of ferrous sulfate, it is necessary to spray the leaves of the plant and water the soil well. For preventive purposes, you can use the solution for plant nutrition. Do not be afraid of an excess of iron in the soil. iron chelate in industrial scale obtained using a drug called "TRILON B".

Iron chelate from ascorbic acid

But you can get iron citrate, which is 3-valent. However, plants quickly convert this form to the divalent form, which they absorb very well. Due to the high cost of industrial iron chelate, the above substance can also be prepared. There are several ways, depending on the acid you choose as an oxidizing agent.

Take 1 teaspoon of ferrous sulfate and dilute it in 0.5 liters of clean water.

Add 10 grams ascorbic acid without glucose content.

Mix everything well, dilute with boiled chilled water up to 3 liters.

You can apply immediately.

Dissolve 8 grams of citric acid in two liters of water in a plastic or glass container.

Mix everything well with a wooden spoon.

Add an incomplete tablespoon of iron sulfate and mix well.

A similar solution can be stored throughout the summer season.

Learn from the article how and why iron sulfate is used in gardening. Read also how to prepare a solution of vitriol for fertilizing plants.

Ferrous sulfate - by appearance similar to blue vitriol, only differs from it in color. Iron sulfate has a bluish-green tint. This salt is obtained by the reaction of the interaction of iron (II) and sulfuric acid. This fungicide has the ability to act only on the surface of plants, without penetrating into its cells. Further details.

Iron vitriol: instructions for use in the garden

The high acidity of the substance causes burns of plant leaves. That is why gardeners recommend using the product in early spring or late autumn, when the leaves fall. In addition, so that fungal infections do not remain below, on the ground, do not forget to cultivate the soil near the plants. Just before the process, remove the fallen leaves around the tree trunks.

The substance is used for:

Development retardation on fruit trees powdery mildew
Getting rid of false dews
Combat gray mold
Treatments anthracnose, coccomycosis, clasterosporiosis etc.

How to prepare a plant treatment solution (concentrations):

For the destruction of lichens on fruit trees a solution of ferrous sulfate with a concentration of 5-6% is used
To get rid of fungal diseases, prepare a mixture of 3-4% concentration

IMPORTANT: For processing garden plants windless, dry, overcast weather is suitable.

Iron vitriol as fertilizer for plants

So that the shoots of shrubs and trees do not die off, the leaves do not turn yellow ahead of time, the flowers have a bright color, iron sulfate is used. Thanks to this substance, horticultural crops receive essential trace element(iron) for their growth and development. A solution of ferrous sulfate can be watered with crops, or the agent is added to manure (100 g of vitriol per 10 kg of compost).

Ferrous sulfate - fertilizer for the garden

Iron vitriol: application in viticulture for processing and feeding grapes

The use of this tool for the vine is possible only when there are no leaves on the grapes, that is, in autumn or spring. It is enough to carry out one treatment per year. If you used ferrous sulfate in the spring, then spraying is no longer necessary in the fall.

A solution of ferrous sulfate creates a thin film on plants after spraying. This ability of this substance is used experienced gardeners. In the autumn they do processing of grapes. The film that forms on plants protects them from small frosts. Don't be alarmed if your grapes bloom a little later than untreated bushes in the spring. Two weeks delay is not critical.

IMPORTANT: Treat very young grape bushes with a 1% solution of vitriol, and spray rooted plants with thicker bark with a 3% solution.

Treatment of apple trees in early spring with iron sulphate

Processing with iron sulphate should be carried out when there is no longer frost on the street, and the air temperature is set within 5-7ºС. Suitable for this process 3% ferrous sulfate solution.

This substance contributes not only destruction of various fungal microorganisms, and also feeds apple tree important element — iron. The very spraying of a mixture of water with ferrous sulfate powder is also useful in that stimulates apple growth and going on increased absorption of carbon dioxide. This process has a positive effect on the formation of such needed by plants substances like chlorophyll.

Processing currants with iron sulphate in spring

All garden crops need constant care, only timely cut, fertilized and processed plants will please their owner excellent harvest. Already in early spring, gardeners should start seasonal work.

You should start by trimming dry branches. Then it is necessary to dig the plant in a circle and fertilize with manure mixed with ferrous sulfate powder (100 g of ferrous sulfate per 10 kg of fertilizer).

After these works, currant branches are processed from all kinds of insect pests and fungal diseases. For such procedures, a 1-3% solution of iron sulfate is suitable.

Processing strawberries with iron sulphate in autumn

Many people love this fruit. But in order to grow it, you need to make every effort. Strawberries are particularly prone to fungal infections. These include:

powdery mildew
Gray rot
Late blight rot
spotting
late blight wilt

An effective means of preventing these diseases of the plant is iron sulphate. It must be applied after harvest. First, fertilize strawberries with slurry with the addition of iron sulfate to it. Cut off the leaves, remove the weeds. Treat the plant bushes with a 0.3% ferrous sulfate solution. For the winter, cover strawberries with lutrasil from severe frosts.

Treatment of chlorosis on tomatoes with iron sulphate

Tomatoes are sensitive to iron deficiency. Even if there is a normal amount of this substance in the soil, chlorosis can still appear in young tomatoes. Outwardly, it is not difficult to determine the disease. Faint yellow spots appear between the veins on the leaves of the plant. And young leaves become completely yellow, dry.

To fix the problem, use a 0.1% solution of iron chelate.

Recipe:

Components:

Cold water - 1 l
Ascorbic acid - 20 g
Iron vitriol - 10 g

Cooking:

Pour water into an enamel container
Add acid and iron sulfate there
Stir the content
Spray plants affected by chlorosis

How to prepare a 3% solution of ferrous sulfate?

Iron sulphate is sold in specialized stores of plant fertilizers. The package usually contains 300 g of powder.

In order to prepare a mixture of three percent iron sulfate, you will need to do the following:

Prepare a plastic container or an enameled bucket
Pour 10 liters of plain water into it
Pour 300 g of iron sulfate into the liquid
Stir the solution thoroughly with a wooden stick.

IMPORTANT: Use the prepared composition for the treatment of garden plants immediately, do not leave it to infuse for a day or two. Otherwise, the mixture will lose its original properties.

Video: Treatment of plants with iron sulphate

Ferrous vitriol (iron sulfate) are crystals with green tint, soluble in water. In the garden, this substance is used to treat trees from pests. The drug is effective, but when working with it, you must take precautions and take into account its features.

Iron vitriol in the garden

Iron sulfate is a contact fungicide. This means that when spraying, it does not penetrate inside, but remains on the surface of the plant. The drug is used in the form of aqueous solutions, which are distributed by spraying. It solves several problems at the same time:

provides prevention of major fungal diseases (scab, powdery mildew, various spots, fruit and gray rot, and others);
destroys insect pests;
helps to get rid of moss and lichen;
disinfects mechanical damage to the bark;
replenishes iron stores in plants.

Important! Iron vitriol, unlike copper, is not suitable for the preparation of Bordeaux mixture.

Advantages

On sale you can find great amount preparations to protect the garden from fungus and pests. All of them differ in composition and mechanism of action. Compared with analogues, iron sulphate has several advantages:

affordable price;
possibility to apply for different types crops in the garden;
high efficiency against fungal diseases, mosses and lichens;
low level of danger to a person when working with him;
the agent does not penetrate into plant cells and cannot accumulate in their greens or fruits.

However, there are several disadvantages that should be considered when buying it. This substance has a short period of action, as it is quickly washed off by rainwater. In addition, it is not used during the entire warm period of the year, so as not to damage the greenery.

When to process?

Treatments with ferrous sulfate are well tolerated by plants if they are carried out according to the schedule. Only 2 sprayings are allowed per year, when there are no leaves on the trees yet. If it comes into contact with green parts, the drug causes chemical burns.

spring

The first treatment of the garden is carried out in early spring, immediately after warming. By this time, the trees should not yet have young leaves or blossoming buds. The drug is used in a low concentration, and the degree of its dilution depends on the condition and type of plant.

It is useful to carry out it before processing the garden mechanical cleaning from last year's grass and dry branches - they often turn out to be a place for a comfortable wintering of insects and fungus.

Advice! For young trees, one spray in early spring will suffice. For an adult garden, additional autumn processing is carried out.

autumn

Autumn processing is carried out after harvesting and leaf fall. It is necessary for the destruction of fungal microflora and insect pests that can winter in the bark of trees. In autumn, this drug is effective. It will completely destroy pests, and during the cold period of the year they will not reappear.

Spraying of adult fruit trees is carried out with a 7% solution of iron sulfate. You can not be afraid to use it in such a concentration - it is harmless to the bark, and before the leaves appear, its action will cease.

Instructions for use

Iron vitriol is small crystals with a characteristic blue tint. Before use, it must be diluted with water in the correct dosage, poured into a spray bottle and distributed over the territory. In addition, there are certain safety rules that must be observed when working.

Preparation for work

A solution of ferrous sulfate helps to get rid of the causative agent of a fungal infection. The fungus can be both directly on plants and on their dry residues and on the soil surface. Regardless of the time of processing the garden, it is first necessary to carry out its mechanical cleaning in order to destroy the source of infection:

remove fallen or last year's leaves and dry branches;
remove dry and damaged shoots on trees and shrubs;
dig the soil around the trunk circle.

To work with iron sulphate, you will need a spray gun. In addition, you need to prepare containers for preparing the solution in advance. Granules are allowed to be diluted in glass or plastic dishes - iron does not react with these substances. After that, the containers are not used for storing food and feed.

How to breed

To prepare the solution, you need to measure the right amount of powder, place it in a container and pour warm water. Many gardeners recommend using a small amount at first. hot water(for better dissolution of the crystals), and then bring the liquid to the desired volume. The concentration of the active substance in the solution will be different:

for the destruction of mosses and lichens - from 4 to 6%;
for the prevention of fungal infection - 3-4%, for adult trees, the concentration can be increased to 5%;
for spraying roses, the drug is used carefully, and its concentration should not exceed 0.5%.

Important! Iron vitriol is not suitable for the preparation of mixtures. It does not combine with lime, insecticides and other substances.

Safety

Iron vitriol refers to substances with a low degree of danger. However, during the preparation of the working solution and spraying the garden, you must follow the safety rules:

prepare working solutions exclusively in glass or plastic containers(metal do not use);
wear thick rubber gloves to protect the skin of the hands;
dilution of the drug and spraying is carried out exclusively with a respirator or with a protective bandage.

In case of accidental contact of the solution with the skin, the likelihood of chemical burns is low. However, it is worth rinsing the skin under running water and follow her reaction for several hours. Redness may form on the mucous membranes, but it quickly passes if the drug is removed in time with water.

From pests and diseases

Iron vitriol is a fungicide, that is, the main purpose of its use remains protection against fungal microflora. However, it also has little effect on insects and their larvae, bacterial infection and other pests.

Fruit trees

The fungus on trees is manifested by blackening of leaves or fruits, as well as the appearance of spots and formations on their surface. different size. The causative agent of fungal diseases becomes especially active with high waterlogging of the territory, frequent precipitation and insufficient ventilation. Young trees can be treated for the fungus once a year, in early spring, and adults will need 2 scheduled treatments.

Solution for fruit trees and berry bushes prepared the same way. The only difference is that due to the thick bark of adult fruit trees, you will need to take dry matter in a higher concentration. With it, you can get rid of the most common fungal diseases:

scab;
powdery mildew;
fruit rot;
black cancer and others.

berry bushes

Iron vitriol is also used for berry bushes. In the garden, they process not only raspberry or currant bushes, but also roses and other shrubs. The drug is effective if it is sprayed twice a year on the territory after preliminary cleaning. It acts against a number of diseases caused by a fungus:

powdery mildew;
anthracnose (often seen in gooseberries, raspberries, currants);
white leaf spot;
columnar rust;
black and gray rot.

A solution of ferrous sulfate is popular for processing vineyards. It is used at a concentration of 2-3% twice a year. It can be used to treat and prevent such fungal diseases grapes like mildew (false powdery mildew), powdery mildew, Alternaria, black, white and gray rot.

Processing Features

Two scheduled treatments are required per year. Each of them has its own goals and features. Spraying time depends on the schedule of awakening the garden after winter, climatic features, temperature regime and precipitation. In addition, it is important to take into account the condition of the plants - if during the year they show signs of a fungal infection, additional treatment in a high concentration will be required.

spring

After warming, the first spraying of fruit trees and shrubs is carried out. The optimal time is before bud break and leaves appear. During this period, the drug can be taken at a lower concentration if autumn processing was carried out on schedule. Even in autumn, the fungus on the trees was destroyed, and during the winter it could not develop.

autumn

A few weeks before frost, the last garden treatment of the year is carried out. Autumn work includes digging the soil with the introduction of a supply of fertilizers, as well as mechanical harvesting and pest control.

The solution can be used at a higher concentration (for mature trees - up to 7-8%), since it will not be able to affect the sensitive leaves and petals of trees. However, it should be understood that the autumn stocks of the fungicide will not work after warming in the spring. It will quickly be washed away by rain and snow, but during frosts, the fungal flora will be inactive.

Conclusion

Iron vitriol is one of the most popular and cost effective garden fungicides. It acts against many types of fungal infection, while being safe for humans. The procedures are carried out according to a specific schedule, which depends on the temperature regime.
