The use of ferrous sulfate in the garden and vegetable garden. Iron vitriol: instructions and correct use in gardening

In order for the plants in the personal plot to grow healthy and give a regular harvest, it is necessary to carry out their regular processing. One of the most simple and available funds used for this purpose is vitriol.

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

It is ferrous sulfate produced by the reaction between ferrous iron and sulfuric acid. Crystals have a bluish-green tint, which distinguishes the drug from copper sulfate which has a pronounced blue color.

The fungicide dissolves well in water and in this form is used for spraying plants. For different types of processing, different concentrations of the drug are used.

You 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 carry any harm to humans.

Purpose of ferrous sulfate

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

1. For the treatment of fungal diseases of shrubs and trees: scab, coccomycosis, powdery mildew, clusterosporiosis, etc.
2. For the treatment of vines from anthracnose, gray rot, powdery mildew.
3. For disinfection of cuts and wounds on tree branches.
4. To combat blotchiness on roses.
5. As a remedy for the elimination of mosses and lichens.
6. For the destruction of harmful insects.
7. As a means for processing vegetable stores, cellars, basement floors, wooden structures in order to get rid of fungus and mold.
8. As fertilizer in the garden.

Instructions for use

Let us give short instruction on practical use ferrous sulfate for processing plants, as well as for use in everyday life.

How to dilute the drug correctly?

To ensure the proper quality of the solution, it is necessary to prepare it correctly.

Pay attention to the following nuances:

1. The container in which the technical vitriol will be diluted must be either glass or plastic. It is not allowed to prepare the solution in a metal container.
2. Ensure that the container is clean. If the container previously contained some Chemical substance, it is difficult to predict the reaction of ferrous sulfate with residues of this substance.
3. Stir the solution thoroughly, slowly. After mixing it initially, it is better to let the solution brew a little, and then mix again. In this case, more iron sulfate will pass into the water.

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

Against pests

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

Also, circumambular circles are processed. For spraying, use a solution at a concentration of 5%. That is, 500 g of sulfate must be poured into a 10 liter bucket. Processing is carried out 2 times a year: in the fall, after leaf fall, and also in the 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 once, in the spring.

Controlling mosses and lichens

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 copes with this problem perfectly. Shrubs and stone fruits are treated with a solution with a concentration of 3% sulphate. Pome trees require an increased concentration of the drug - 5%.

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

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

Whitewash the damaged branches with this composition. Ash hood is being prepared in the following way... 1 glass 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 used no more than 3%.

The 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.

Chlorosis

Signs of chlorosis are pale leaves of 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 fill the lack of iron. For 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. Plants are processed several times, every 5-6 days. A sign of recovery is the return of the leaves to their normal green color.

If chlorosis annoys regularly, then preventive sulfate treatments can be carried out, reducing the concentration of the fungicide to 10 g per 10 liters of water. It is enough to carry out prophylaxis on a weekly basis.

Spraying the vine

Grapes require a significant amount of iron. For this ideal option it is ferrous sulfate. It can be used in two ways: spraying and root feeding.

Foliar processing

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

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

Note that a lower drug concentration is applied in the spring.

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

Root dressing

In addition to spraying, ferrous sulfate is also used for application under grape bushes. It is best to combine this process with watering. If the vine gives a small increase, the leaves are pale, and the bunches ripen with a delay or do not have time to ripen at all, then the grapes clearly lack iron.

Alkaline soils are especially poor in iron. If you notice such signs on your grape bushes, add a little iron sulfate to the water for irrigation. It is not necessary to dilute a lot of vitriol in water. It is enough to add 10-15 g of the preparation to 10 liters of water.

Grape seedlings processing

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

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

Spraying berry bushes and trees

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

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

This 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

Pathogens often get on open wounds and tree cuts, causing damage to the wood. The infection can lead to serious disease and even death of the tree.

Having treated the wounds with iron sulfate, we get rid of the infections already existing 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 fertilizer

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

Top dressing is done in two ways:

1. Root. Vitriol is brought under digging, after mixing it with compost. For 10 kg of compost, take 100 g of ferrous sulfate.
2. 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 feeding.

Not everyone knows that a highly effective fertilizer - a chelate - can be made from ferrous sulfate. Its value lies in the fact that it stimulates photosynthesis in plants.

Price finished product unusually high. Making it on your own will cost a hundred times cheaper. The recipe for making a chelate is as follows:

3 liters of water is 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 becomes light orange in color. It is necessary to use the ready-made solution within 1-2 hours after preparation, therefore it should be prepared immediately before use. Plants are sprayed with chelate or applied under the roots. Apply several times during the season.

Basement and vegetable storage processing

Iron sulfate 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, the pathogenic microflora is not viable.

With a solution of ferrous sulfate 10% concentration, 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 is extremely important for a gardener to know about:

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

Compatibility with other drugs

It should be borne in mind that ferrous sulfate cannot be mixed for spraying with organophosphate preparations, which are usually used to destroy plant pests.

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

Precautionary measures

So that iron sulfate does not harm the gardener, you should adhere to certain safety rules when working with the drug:

1. Spraying in the garden is best done with protective gloves and a respirator. Though this substance is not a poison, it is better to protect yourself from getting the fungicide into Airways and on the skin.
2. 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 correct and timely use, ferrous sulfate can provide effective assistance in the treatment of plants and be a reliable supplier of iron for them.

Many gardeners find ferrous sulfate to be cheap and effective means from pests and plant diseases. The substance is quite multifunctional: treatment of trees, cesspools, disinfection, fight against fungus - all this is within the scope of its action. The use of ferrous sulfate from pests in the garden gives a good effect if all proportions are correctly observed and not overdosed.

Ferrous sulfate is a salt formed in the combination of iron and sulfuric acid. Appearance- a greenish powder or granular substance that dissolves well in a liquid. The duration of the action is 2 weeks. It must be stored in a clean container in a dry, dark place.

The composition must be prepared carefully, in exact accordance with the amount of a particular substance, with a high concentration, burns will appear on the leaves and bark, with a low concentration, the substance will cease to work.

In grocery stores, iron sulfate is sold in the following forms:

• small bags 200 grams;
• bags 20, 40, 55 kg;
• tons.

V household a small package of iron will be enough, it is enough for one or two treatments. The only question for gardeners: how to process with iron vitriol garden planting without harm to their lives?

A chemical is a substance that can cope with many tasks of an economic purpose. Iron sulfate helps best of all against pests and fungal diseases, but many practice spraying them in a number of other cases:

This chemical is used for the following diseases:

1. powdery mildew;
2. scab;
3. rot;
4. oidium;
5. anthracnose;
6. coccomycosis, etc.

Important: ferrous sulfate does not protect against bacterial diseases, it is not used for indoor flowers.

One of the most hazardous substances used on the farm is ferrous sulfate. Instructions for its use are indicated on the package with the substance.

There is a concentration table for treating various diseases:

To prepare a 2% solution of ferrous sulfate, dissolve 0.5 tablespoon in a liter of water. Orange color solution is a sign of correct preparation.

Iron sulfate helps plants survive in spring frosts, as it delays the appearance of buds by a week.

Most often, sulfate helps to get rid of harmful insects that cause serious diseases:

• moths;
• cabbage scoops;
• leaf beetles;
• sawflies.

A 3% solution helps from them, which clogs the tree in a film that does not allow air to pass through. After pollination, the general condition of the fruit tree will improve, moss, mushrooms, growths on the trunk, which pulled out its life, will disappear vitality... In some cases, in addition to treating the trunk and branches, irrigation with iron sulfate is used. For this, the active concentration must be diluted to 1.5-2%.

From mold fungi that have spread through the basement, storage, warehouse, dilute 100 grams of iron sulfate and dissolve in 10 liters of liquid, spray the affected areas with iron sulfate.

The substance is sold in many stores, which explains its popularity among gardeners. Good way disease prevention - foliar feeding.

It is necessary to dilute 5 grams of the chemical in 8-10 liters of water and use it to fertilize potatoes, cabbage and tomatoes.

Precautionary measures

Like anybody chemical agent, ferrous sulfate is quite dangerous, therefore, when using it, you must follow basic safety rules:

1. Spray the substance in a protective suit, gloves, goggles and a respirator. The procedure is carried out using special equipment.
2. After handling, discard gloves, rinse the uniform, glasses, shoes and containers thoroughly.
3. Do not mix powder with lime - use clean water when dissolving.
4. The drug should not be mixed with other substances from pests and diseases.
5. Iron vitriol is hazard class 3 for humans. For pollinating insects, it is harmless.
6. Concentration in 1% held by human skin and plant bark, denser content active substance can disturb the bark of a tree.

Conclusion

Iron sulfate is most often used in autumn and spring, but in rare cases additional processing is allowed.

Many of us do not know, or have forgotten the old, but time-tested remedy for fighting diseases, pests and lichens - iron vitriol! What are the pros and cons of using this drug, what are its features?

Whitewashing trees with iron sulfate Iron sulfate is effective against grape diseases

Ferrous sulfate or ferrous sulfate - effective and universal remedy... It not only helps fight pests, but also improves fruiting and regenerates old trees. With the help of this fertilizer, the plant receives the iron necessary for its respiration and growth, the lack of which can cause many fruit crops a disease such as chlorosis.

Iron sulfate is widely used in horticulture. If you need to whitewash trees, mix 100 g of powder in a liter of water for an excellent insect repellent and scorching sun... The same solution can be used to disinfect the hollows and heal tree wounds.

For processing crops against scab and septoria a 5% solution is used, and for black spot treatment on roses take vitriol in a concentration of 0.3%.

Protect stone fruits from moss, lichens and gray mold a composition of 30 g of powder and 1 liter of water will help.

For processing seed crops you need to take a little more - 50 g of powder.

Iron vitriol is beautiful prophylactic agent against necrosis, anthracnose and other diseases of grapes. The first time the vine is treated in early spring with a 5% solution, after two weeks the procedure must be repeated.

Pest control

Iron sulfate is used in horticulture as an insecticide to kill harmful insects. It kills not only pests, but also their larvae and eggs. Vitriol is very effective against worst enemy trees - apple sucker... To combat it, it is necessary to spray the plants and the soil around them with a 1% solution before budding. The best time processing - mid-April, when the insects have already laid eggs. The second time the trees are treated with a 5% solution in the fall, when all the leaves have fallen off.

Iron vitriol as fertilizer

The use of ferrous sulfate in horticulture is not limited to its fungicidal and insecticidal properties. He is also good fertilizer and allows in an easily accessible form to deliver iron to plants, without which they cannot grow and develop normally.

Lack of iron leads to yellowing and dropping of leaves, death of shoots, poor fruit development.

Ferrous sulfate is an excellent fertilizer for feeding potatoes, tomatoes, cabbage... Approximately 7 g of the drug is diluted in 10 liters of water and watered with the resulting plant composition. It is also brought in together with the compost for digging. To do this, for every 10 kg of organic matter, 100 g of vitriol is taken.

The use of copper sulfate

The antifungal properties of copper sulfate have long been known, therefore, in horticulture, it is primarily used as a fungicide. They are treated with flowering ornamental plants, fruit bushes and trees from moniliosis, anthracnose, of various kinds rot, spotting, scab and other diseases.

The use of copper sulfate in horticulture is effective both for the prevention and treatment of viral and fungal diseases. Processing is carried out in early spring, late autumn and during periods of active action of certain pests.

A solution of copper sulfate is not stored for a long time, so it is prepared just before use. Plants are usually sprayed with 1 or 3 percent before bud break.

You can use copper sulfate and for disinfection of roots and seedlings of raspberries, gooseberries, currants, as well as strawberry and strawberry mustache. To do this, they need to be immersed in a 1% solution for three minutes, and then rinsed thoroughly.

When spraying, remember the safety precautions Handle with copper sulfate before the buds appear

How to prepare Bordeaux liquid

Bordeaux liquid has been used for about a hundred years and is one of the most effective means of preventing fungal diseases in plants. To prepare it, you need to add 100 g of copper sulfate and slaked lime to a bucket of water (10 l). First, vitriol is diluted in 5 liters of water, lime is extinguished separately in a small amount of liquid, and then it is brought to a volume of 5 liters and filtered. Next, the two parts of the solution are mixed, but not immediately, but gradually, stirring constantly. If everything is done correctly, then the composition has a light blue tint.

Copper and iron vitriol today gave way to more modern chemicals and are not as popular as they used to be, and in vain. Many gardeners should take note of the undeservedly forgotten and very effective means that will help get rid of all kinds of pests and fungi.

Every gardener has a dream - to see his private plot beautiful and comfortable, and many manage to achieve this. Increasingly, people are abandoning potato beds in favor of manicured lawns and garden trees with berry bushes... But for those who begin to develop this direction, the question often arises - how to make your garden healthy and get rid of diseases and pests. Of course, modern market has a huge range of drugs that can keep the plant healthy, but not all of them are safe to use. That's why experienced gardeners and gardeners prefer to use time-tested fungicides, which include ferrous sulfate and copper sulfate. The use of these drugs allows for a successful fight against fungal diseases and at the same time causes minimal harm to the environment and humans.

Iron vitriol, in contrast to copper, has the form of a fine-crystalline powder. It has universal properties that can not only fight against fungal diseases, but also to improve the fruiting of old fruit trees... Iron vitriol is necessary in the case of chlorosis, when plants are deficient in iron. It is used to disinfect wounds and hollows, as a component in whitewashing trunks to protect against diseases. A 5% solution of ferrous sulfate is used against scab and septoria, and 3% is used against black spot.

One of the common mistakes is adding ferrous sulfate to a lime solution. Lime can be added to copper sulfate, but not to ferrous sulfate.

inkstone

Remember! Iron sulfate is not used to kill ticks, rodents and as a growth stimulant.

Copper sulfate, in contrast to iron sulfate, can be used for feeding in case of a lack of copper in the soil composition, but it has become more widespread as a fungicide - a means to combat fungal diseases. And to this day no more have been found effective methods fight against various rot and fungal infections than copper sulfate and preparations with its content.

Every day spring reminds of itself more and more. Nature begins to awaken from winter sleep. And the gardeners come ...

Copper sulfate in horticulture

Copper sulfate (or copper sulfate) is a salt formed as a result of the interaction of copper with sulfuric acid, one of the most time-tested remedies, the effectiveness of which gardeners were able to appreciate many years ago and still have not been disappointed in its action.

It is used both in pure form and as a part of various copper-containing preparations ("Cupronaft", Bordeaux and Burgundy liquid, "Copper oxychloride", "Medex" and others). It looks like crystals of a beautiful blue that lose their color on contact with air. Has antiseptic and astringent properties, when heated, it is capable of forming gases hazardous to humans. Due to its suppressive effect on the development of fungal foci, it is successfully used in housing construction for treating wood from mold and protecting it from decay. Indispensable in horticulture copper sulfate for disinfection of wounds on tree trunks and for the fight against plant diseases.

Copper sulfate

Use of copper sulfate

Preparations based on copper sulfate are often used as effective remedy to suppress various diseases plants, they are treated with trees, berry and ornamental shrubs from moniliosis, spots, anthracnose, various rot, scab and many similar diseases caused by the spread of pathogens of fungal infections.

For preventive purposes, it is not recommended to constantly grow plants at risk of infection with fungal infections in the same place so as not to expose land repeated treatment with preparations containing copper sulfate and not contribute to its accumulation in the soil. TO perennial plants, grown for a long time in one place, it is recommended to use alternation of spraying with copper sulfate with preparations containing iron. For example, in autumn to spray plants with iron sulfate, and in spring and summer - with copper content.

Containers for stirring and storage should be either plastic or glass. When working with copper sulfate, do not use metal containers.

We have already mentioned above for which diseases it is necessary to use copper sulfate. The horticultural use of this contact fungicide is widespread.

Most often vitriol is used in early spring, while the buds are closed, or in late autumn, after leaf fall. Required concentration: for ten liters of water, one hundred grams of dissolved copper sulfate.

Treatment with copper sulfate during the growing season of plants is possible in the composition of Bordeaux liquid or other copper-containing fungicides. A pure solution of copper sulfate can damage the leaves, so in the summer it is not worth treating trees and shrubs with it.

The use of a working solution to suppress fungal diseases should not exceed 2 liters per young plant (up to six years), for an older fruit-bearing tree - no more than ten liters and up to one and a half liters per berry bush. The solution is not stored and is prepared immediately before use; for this, copper sulfate is dissolved in a small amount of water and only then brought to the recommended concentration by adding water.

Plants are sprayed in calm weather, in the early morning or evening, to prevent the solution from getting on bees and beneficial insects... It is recommended to spray at least four hours before expected rainfall. It is advisable to use copper sulfate to protect against diseases during a period when the disease has not yet spread to the entire plant, as well as for preventive purposes.

The main description of the disease Black spot is caused by the fungus Marssonina rosae, which when it gets on plants ...

The use of copper sulfate

Used for the following purposes:

• as an antiseptic for treating wounds on the trunks of fruit trees;
• for disinfecting the roots of seedlings (for example, roses) before planting;
• for disinfection seed material before sowing;
• for processing seed potatoes before planting.
• for disinfection vegetable storage, cellars and wooden buildings in order to prevent the development of mold and destruction of wood.
• against apple scab;
• from stone fruit coccomycosis;
• against curly peach;
• from anthracnose and septoria gooseberry and currant;
• from some spots and downy mildew;
• against clasterosporium disease.

Copper sulfate as fertilizer

In regions where copper is lacking in the soil, it is used as fertilizer. The use of copper is especially necessary in areas of former peatlands or on some sandy soils where copper in the ground is in insufficient quantities. It is possible by some signs to determine the lack of copper in the soil, since the plants growing on it shrink the leaves, signs of chlorosis and necrotic spots appear. Foliar top dressing with a 0.01-0.02% solution of copper sulfate (1-2 grams of copper sulfate per bucket of water) can help. Spraying is best done in calm weather without wind.

Preparation of Bordeaux liquid

To prepare the composition, you need one hundred grams of copper sulfate, one hundred grams of lime and ten liters of water. Copper sulfate is diluted in a bucket in five liters of water, lime is separately quenched in a small amount of water, water is added up to five liters, filtered. Both compositions are combined with constant stirring. The resulting solution should be sky blue.

Precautionary measures

The use of copper sulfate can be considered moderately harmful to humans. It is, of course, toxic and, if a large dose enters the body, it can cause poisoning. The minimum dose, which is lethal for humans, is 11 mg per kilogram of weight, but this is an exceptional situation and it is impossible to get such an amount of copper sulfate by accident, inhaling it while spraying plants.

It is better to keep the eyes and mucous membranes during processing, and in case of accidental ingestion of vitriol, they should be immediately rinsed with water. It is better to spray in a respirator or mask, and after work take a shower or at least wash your face and hands with soap and water.

Important! There are quite a few options for using copper sulfate in gardening, but in order to obtain the maximum effect and maintain the biological balance in the development of plants, it is necessary to comply with the instructions for preparing the mixture and strictly observe its dosage.

Iron vitriol: characteristics and use

Iron vitriol is produced in the form of a blue crystalline powder with a greenish tint. A solution of ferrous sulfate is a frequently used agent that is used in summer cottages.

Has an unlimited life if stored properly.

Fight against plant diseases

Iron sulfate in horticulture - very affordable, tested over the years and inexpensive remedy... Therefore, let us consider in more detail the use of iron sulfate in horticulture.

inkstone

Iron sulfate is useful in such cases:

• processing the walls of the basement and vegetable store;
• heals cuts, hollows, wounds on garden trees;
• spring and autumn whitewashing of fruit tree trunks;
• the fight against lichens;
• used as fertilizer;
• disinfectant cesspool, country toilet.

Diseases from which treatment with iron sulfate will effectively protect:

• powdery mildew;
• downy mildew;
• clasterosporium disease;
• coccomycosis;
• anthracnose;
• gray rot.

Plants are treated with iron sulfate in early spring, before bud break, or in autumn, after leaf fall. They spray not only the plant itself, but also the soil around it. Iron sulfate should not get on green leaves, otherwise burns on them are possible. A 3-5% solution is used to treat trees and shrubs. For cooking working mixture you need to dissolve 300 or 500 grams of ferrous sulfate in 10 liters of water. Shrubs and young trees are preferable to treat with a three percent solution, for mature trees or for an old neglected garden, a five percent composition is used. To get rid of lichens and mosses on the bark of trees, treatment in early spring with a solution of 6% concentration will help.

Note! Processing is carried out in calm, cloudy and dry weather.

The use of ferrous sulfate for disinfection

An excellent tool for treating the walls of the cellar is a solution of ferrous sulfate. The tool is notable for its cheapness and its not strong toxic properties. The solution is prepared using a 10% concentration. The working fluid is applied to the walls with a brush; to improve the effect, you can add clay until a creamy consistency is formed. This treatment helps fight fungi and insects. The procedure is repeated twice in the fall before the vegetables are placed for storage, and after that the cellar is well ventilated.

To eliminate odor from cesspools, use the following composition: 250 g per 5 liters of water. It is also used when fungus appears in houses, for treating walls, solution concentration: 150 g per 1 liter of water.

Disinfection of greenhouses is carried out using a solution at a concentration of 150 g per 1 liter of water, spray or brush all wooden parts of the greenhouse with a brush.

To treat wounds on fruit trees you need to mix 100 g of vitriol with 1 liter of water and carefully go through all the damaged areas with a brush.

Ferrous sulfate as fertilizer

Ferrous sulfate powder is not only a means to fight diseases, but also an excellent fertilizer. With a lack of iron in many plants, early yellowing of the leaves is observed, the death of shoots, the leaves become faded, not so green. Without it, the normal existence of cultures is impossible, chlorosis develops in plants. As a fertilizer, a solution of powder is used in horticulture for foliar feeding of potatoes, tomatoes, all types of cabbage and other crops. To do this, dissolve 5-10 grams of powder in a container, pouring 10 liters of water. Water for the solution must be taken soft and not mixed with lime.

Gardeners with great experience have learned how to prepare iron chelate, to obtain it, it is necessary to dilute two teaspoons of citric acid in a bucket of 10 liters, after completely dissolving in water, put one tablespoon of ferrous sulfate in the resulting solution. With this composition, the plant is watered at the root with chlorosis.

Precautionary measures

Iron sulfate is not as toxic as copper sulfate. But working with him, you also need to adhere to certain rules. If the substance comes into contact with the skin, rinse thoroughly big amount water as quickly as possible. If you experience a burning sensation, consult a doctor. Avoid contact of the solution or substance with eyes and mucous membranes. Be sure to use protective clothing, gloves, after working with the solution, you must thoroughly wash your hands and face.
