Copper sulfate is a popular and inexpensive fungicide that protects flowers from fungal and other diseases as well, and acts against aphids. In addition, the drug contains useful substances that contribute to the fact that the bush becomes more luxuriant, and the flowers grow larger. For roses, iron vitriol is also used. It must be distinguished from copper, it is used for feeding, destroys mold.

In what cases is iron sulfate used?

Gardeners often use ferrous sulfate because it is not only effective, but affordable. It is actively used to combat:

insect pests;
mosses, rot, lichens;
infection on the surface and in the hollows of trees;
lack of iron;
fungal plant diseases.

Iron vitriol finds its application not only in gardening, but also in construction as an additional antiseptic agent when processing wood from fungus, rot and mold.

It should be noted that ferrous sulfate has an increased acidity, when it comes into contact with the leaves, it leaves burns, therefore, it should be used for treating trees and shrubs in autumn and spring, when the leaves have not yet appeared or when they have already fallen off. Most often, it is at this time that fungal foci appear, the reason for this is plant residues on the surface of plants, as well as the soil around them. In this case, not only trees are treated with a solution, but also the soil.

Iron sulfate is also used as whitewashing of plant trunks in preventive and disinfection measures. To do this, it is necessary to dilute 100 g of ferrous sulfate in 1 liter of pure water.

Chemical remedies for the prevention of rose diseases

Ferrous sulfate (FeSO4), popularly known as ferrous sulfate, is a crystalline substance (salt) formed by the interaction of biphasic iron with sulfuric acid at a concentration of 53%. Available as a granular free-flowing powder of bluish green, sometimes grayish color, readily soluble in water. The drug is hygroscopic, therefore it is recommended to store it in a dry place in a tightly closed container, under these conditions its shelf life is unlimited.

Sulfur is also not only a fungicide, but also a trace element necessary for normal plant growth. What is not an argument in favor of the advantages of the drug over other similar drugs?

As for the effect of ferrous sulfate on plants and soil, it should be noted that this is a contact fungicide, it does not penetrate into plant cells, and is rather quickly and easily washed off with water. It is safe for humans even during processing. Of course, one should not neglect protective measures (gloves, mask), but if, nevertheless, a drop of the product gets on the skin, nothing terrible, including a burn, will happen. You just need to rinse your skin with cold water and not worry about the consequences.

Novice flower growers often confuse copper sulfate with iron sulfate.You need to know that these are completely different agents in composition, and, therefore, the principle of action and purpose are also different for them. Iron vitriol is more effective in terms of strength, but its field of application in horticulture is not so wide.

Iron sulfate or copper sulfate is used as a prophylactic agent against plant diseases and pests.

Many gardeners try to choose roses that are resistant to diseases, but even they should be protected from possible diseases. Even if your plot is perfectly tended, danger can arise from a nearby garden or from wild plantings. This is why you shouldn't rely on chance and treat roses for infection.

For this, both long-tested and modern drugs are used.

Iron vitriol is active against many fungi, including powdery mildew and peronosporosis.

Chemically, ferrous sulfate is ferrous sulfate, otherwise it is ferrous sulfate. It is a green crystalline salt, readily soluble in water. In horticultural practice, iron sulfate is used specifically for late autumn processing of plots. It is used much less often in early spring.

An aqueous solution of iron sulfate has the following properties:

is a strong contact fungicide;
contains up to 53% of active iron, as well as sulfur, and in strong dilution can serve as micronutrient fertilizer;
in an increased concentration, it exhibits some insecticidal properties and can be used to expel wintering larvae and adults of insect pests;
scares away rodents from treated plants.

Why process

The queen of flowers, a soda rose is a decoration of any front garden. Often, a luxurious bush needs help in the form of antifungal treatment, pest control and feeding.

For this purpose, it is convenient to use a time-tested remedy called copper sulfate. Since roses are not resistant to various diseases, treatment is best carried out for prevention, constantly.

An integrated approach, including processing in autumn and winter, will eliminate the development of dangerous diseases that provoke the death of the shrub.

Each rose in the garden has its own story: one came from distant lands, the other was grown from a cuttings, the third was donated by a loved one. Naturally, we are worried if our favorite flowers are sick. Most often this happens in late summer - early autumn. Fortunately, there are remedies to deal with adversity.

A well-kept rose garden is the main decoration of any garden plot. But the “queen of flowers” is gentle, vulnerable and capricious, as befits a royal person.

It has many natural enemies, among which the most dangerous are fungal infections that can destroy more than one plant in a short time. Prevention here is many times more effective than combating the spread of the disease, since it is difficult to identify all its foci.

One of the most effective measures is recognized to be the treatment of roses with iron sulfate in the fall, before sheltering for the winter.

The fungicide will prevent fungal spores from multiplying, which form in a humid environment under fallen leaves or polyethylene, which protects the flowers from the cold.

In addition, the chemical compound contains a useful element - sulfur, which plants need during dormancy and when they leave it.

In the spring, when the protective winter coating is removed, rose bushes should be additionally sprayed with copper sulfate, then they will be reliably protected from fungus and will be able to delight with a healthy look, as well as lush, long flowering.

The queen of the garden, the rose, is not ignored not only by the person. Numerous diseases, pest attacks damage the health and beauty of the gardener's favorite.

The rose is especially vulnerable in early spring, since it has weakened over the winter.

Therefore, it is very important to process roses with high quality after winter in order to prevent infection of the bushes with infections, to protect them from the first hungry pests.

For successful wintering, roses are fed in autumn with potassium-phosphorus fertilizers and sprayed with anti-infection agents. Even if the roses look healthy, preventive measures are needed. After all, the disease does not manifest itself instantly, the infection lasts 2-3 weeks, so it is dangerous to count on luck. Roses are healed with purchased fungicides and folk remedies.

When processing plants, protect the respiratory system with a mask, and hands with gloves, take a shower after spraying

Autumn treatment of roses with iron vitriol is aimed at:

protection of plants from freezing in winter;
preventing the appearance of pests;
protection from rodents;
prevention of fungal diseases.

In addition to spraying, of course, roses will also have to be well covered for the winter. Only in this case can you be sure that the shrub will safely survive the cold.

Let's get acquainted with the basic rules for processing roses with iron vitriol in the fall.

How to propagate?

The easiest way to propagate roses is by cuttings:

Harvesting - when buds are formed, cut off the shoot and make a cuttings from the central part, 5-8 cm long with 2-3 leaves. The bottom edge should be under the kidney itself, and the top one centimeter above the kidney.
Before planting, place the cutting in a rooting stimulator for a day. For example, in water with a teaspoon of honey.
Plant in a box or soil, deepening by 2-3 cm, be sure to add a substrate of river sand and cover with a glass jar.
After planting, maintain high humidity by spraying.

Copper sulfate: tips for preparation and use

How and why to use iron vitriol for roses in autumn is an urgent question for all gardeners. In this article, we will consider not only how to dilute copper sulfate for processing roses, but also why it needs to be done, and whether it can be replaced with something.

Roses are wonderful plants that will brighten up any area. But in order for the plants to be healthy and strong, and their flowering lush and beautiful, it is necessary to carry out high-quality care of the roses.

Care is especially important in the spring, because the plants have survived a long winter and they need to gain strength. You need to start leaving until the plants start growing.

Below will be described how to care for the plant and what activities need to be done.

There is no single instruction for breeding ferrous sulfate. Experienced gardeners distinguish between different concentrations of solution for different types of plants:

For stone fruit crops such as apricot, peach, clay, plum, sweet cherry, cherry, you need to make a 3% solution. Method of preparation: Dissolve 300 g of ferrous sulfate in 10 liters of water. Spray bare branches and trunk before the onset of cold weather. Process the vine in front of the shelter.
For fruit pome crops such as grapes, apple trees, pears, a 4% concentrate is prepared. Method of preparation: dilute 300 g of ferrous sulfate in 10 liters of water.
For these types of horticultural crops, it is possible to use a 5-6 percent solution. Method of preparation: according to the same algorithm as mentioned above, it is only necessary to increase the amount of the product - dissolve 500-600 g in 10 liters of water.

Spraying with iron vitriol from harmful insects is carried out with a 5% solution, it is better to carry out the procedure in late autumn. This will help get rid of insects that hibernate in the bark of trees.

For spraying against moss and lichen rot, a 3 percent solution is used for stone fruit species, and a 5 percent solution for pome plants.

Treatment of trees with iron sulfate in the autumn as a preventive measure is carried out with a 1% solution (100 - 150 g of powder per 10-15 liters of water). It is useful to spray damaged areas of plants with such a concentrate.

Spraying trees with iron sulfate

Iron vitriol is used as tree feeding in case of iron deficiency in the soil both in autumn and spring. Chlorosis of young leaves is considered a sign of iron deficiency, while the old ones retain their color. The owners of grapes, apple trees, plums, and raspberries most often face the increased sensitivity of crops to iron deficiency.

This substance is capable of delaying bud opening, if the treatment is carried out with a 3-6 percent solution, the delay lasts about 7-10 days. This feature can be used during the spring frost.

The following disadvantages of this substance are distinguished:

ferrous sulfate is not effective in combating bacterial plant diseases;
when fighting pests and fungi, it is useless in low concentrations (1 percent or less);
the protective effect lasts up to 14 days.

An aqueous solution of iron sulfate in various concentrations in horticulture is in demand. It is applied with a spray gun, in some cases with a brush. It is quite simple to prepare it.

The liquid is prepared only in a glass, plastic or enamel container.

It is advisable to take soft water for breeding - rain or snow. The resulting liquid is an antiseptic, has an acidic reaction.

In each specific case, different concentrations are needed. Let's take a look at the instructions and how they differ for different trees and shrub species.

Grapes

Similar to the trees in the garden carry out the autumn processing of grapes.

The processing times are the same: before and after the growing season.

The dosage is also the same: Prepare a 2 - 3% solution (200 - 300 g of ferrous sulfate per 10 liters of water).

But the spectrum of diseases for the vine is already much more extended:

Anthracnose,
Bacterial cancer
Spotted necrosis
Mildew.

The treatment is carried out by spraying, necessarily BEFORE COVERING, but AFTER CUTTING.

The order of autumn events is described in more detail in one of the issues of the magazine "My bed of abundance":

After harvesting late varieties of grapes, water charging of the grapes is carried out.
In October, after the first slight frost and after all the leaves have fallen off, the grapes are pruned.
In mid-October, pests are treated with a water-salt solution: 10 tablespoons of salt and 5 tablespoons of soda are diluted in 10 liters of water and the vine is sprayed with the resulting solution.
At the same time, the vineyard is treated against disease with a solution of ferrous sulfate (400 g per 10 liters of water) or copper sulfate (100 g per 10 liters of water).
With the onset of stable frosts (-3, -5 degrees), as a rule, in early November, the grapes are covered for the winter.

Interestingly, this source recommends a more concentrated solution for processing grapes: 400 g per 10 liters of water.

Features of spraying roses with iron sulfate in autumn

The first and most important thing that you need to know when using the drug is that the treatment of roses with iron vitriol is carried out in the fall, and not in the spring, as not very experienced growers sometimes do. Spring treatment with the product is acceptable for fruit trees, and then only before bud break. As for roses, spraying the leaves and shoots leads to the formation of brown spots (burns), which are superficial, and do not harm the stems, while the leaves cannot be restored. That is why the treatment of roses is carried out in the fall, after the leaves have been removed or fallen off.

Ferrous sulfate can be used for any fruit, berry crops, or flowers, but in each case it is necessary to adhere to a certain concentration of the agent. For prophylactic treatment of roses, according to the instructions, a 3% concentration of the drug is recommended - this is 30 g / 1 liter, or 300 g / 10 liters. It is this concentration that experts advise to adhere to when processing bushes in the fall.

If the roses have been affected by black spot disease, and this happens, as a rule, at the end of spring, when the leaves have completely blossomed, then the bushes are sprayed with a weaker solution (1%) on the leaves several times with an interval of 7-10 days. The activity of the drug after treatment lasts for 10-14 days, but it must be borne in mind that it is easily washed off by rain, so the time for spraying should be chosen taking into account the weather.

It is not recommended to cover wet roses - after processing, the plants need to be given time to dry, and all fallen leaves must be collected and burned. It is not allowed to use ferrous sulfate simultaneously with other fungicides, as well as mixing with lime - this method is mainly used to whitewash the trunks of garden trees, but flower growers who grow roses should also be aware of this.

Garden rose - the queen of flowers - has always been a true decoration of any garden, flower garden. Perhaps there is no such flower bed in which the main place would not be occupied by the luxurious bush of the beautiful rose.

But, since this plant, on the one hand, is perennial, and on the other hand, it is very thermophilic and gentle, careful care is necessary for it.

Unfortunately, rose bushes are highly susceptible to the effects of various fungi, and the fight against them, as you know, requires an integrated approach and constancy. In this review, we will talk about the features of spraying rose gardens with iron sulfate in spring and autumn.

In general, when growing fruit and flower crops, gardeners use a wide variety of fungicidal preparations - all of them are necessary in their own way. Along with the protective properties, vitriol also contributes to a more active, correct development of plants, it can serve as a good fertilizer.

This tool is truly time-tested: ferrous sulfate has long been used in agriculture. The drug is able to protect roses from the following dangerous diseases:

gray rot;
powdery mildew;
coccomycosis, etc.

In addition, the preparation maintains the iron balance in the soil, saturating the soil with this essential mineral. Thanks to the use of ferrous sulfate, you can:

protect roses from chlorosis (yellowing of the foliage);
provoke shrubs for rapid growth of shoots, landscaping;
activate abundant budding.

Answers to Usage Questions

There are peculiarities in the use of copper sulfate in gardening. The rules applied to horticultural crops are not applicable to roses. For example, to treat fruiting trees, 5% solutions are used in the spring, while such a concentration will simply kill the rose bush.

A solution of even small concentrations is harmful to the soft tissues of the plant, immature shoots and leaf mass, because blackening after processing is natural. We must wait for spring. And then remove the shelter and see what happens to the bush. If the roses have received a chemical burn, they are pruned to soft tissues, the sections are treated with crushed activated carbon. You can not expect rapid growth and flowering in the coming season, the main task is to save a weakened bush, therefore, you need to abandon the use of fertilizers.

Precautions

Do not confuse ferrous sulfate with copper sulfate, which is more dangerous for the human body. Iron sulfate belongs to the third class of toxic substances, the substance is not flammable and not explosive. When working with iron sulfate, special protection of a person is not required, but care must be taken that the solution does not touch the mucous membranes of the eyes and mouth. If the concentrated solution gets on the skin, it should be immediately washed off with plenty of soap and water.

It is forbidden to store near food and tableware. Thus, there are more advantages in using ferrous sulfate for treating trees in autumn than in spring.This is due to the fact that in the fall there are no leaves that the iron sulfate burns. A bare tree can be processed without fear of harming it. It is also very convenient to use before wintering, providing disinfection of the plant.

Each owner of a summer house or private house needs to prepare for the winter period. Your future arrangement of affairs in the spring depends on this preparation. By treating the garden in the fall from various diseases and pests, you direct your efforts at most to cleaning from pests and to fighting harmful insects, various microorganisms that excite all kinds of diseases, rodents and the influence of weather conditions.

Autumn processing of trees is carried out in order to combat fungal and bacterial diseases, as well as some pests. This event is considered preventive. Various infections that have survived from the fall will reactivate with the onset of warm days, so caring gardeners are carefully studying how to treat the garden in autumn with urea and iron sulfate from diseases and pests.

The substance is classified as low-hazard (3rd class). Does not burn, does not explode.

Ingestion of a large amount of the drug causes a general toxic effect, indigestion, irritation of the skin and mucous membranes. An ambulance is required.

With competent agricultural work, problems do not arise. Spraying is carried out in calm weather, in protective clothing, in a “Petal” respirator, and in gloves. Avoid sedimentation of particles in the respiratory tract, as well as on the eyes, skin and mucous membranes. In case of contact, rinse with water.

Advantages and disadvantages of the drug

I have been growing roses on my site for a long time. Today I want to tell you how to properly process the plant, what preparations you need to use.

Let's get acquainted with all the features of this fungicidal agent, find out what advantages it has, as well as its disadvantages.

Minuses:

Strict processing time limits.
The protective effect is no more than a half moon.
The substance is easily washed off by rain.
Does not help against bacterial and viral diseases.
An overestimated concentration can destroy (burn) the plant.
Low concentration is useless.

Positive points:

Low cost of the drug.
Long shelf life.

No toxicity (in permitted doses) for plants, humans, and the environment has been identified.

Iron vitriol is deservedly included in the list of demanded drugs. With proper use, it gives excellent performance in terms of cost / effectiveness ratio, protects plantings from diseases and fungi.

How to spray bushes and trees in autumn

Roses are demanding on growing conditions. They need constant anxious care, as they are often exposed to diseases and pests. At the first signs of disease, it is necessary to take action, since the spread of disease from sick to healthy plants occurs very quickly.

The rosary may die. The main prevention of spread is the exact adherence to the cultivation technology. Only in this case, you can get beautiful and healthy buds.

Autumn spraying should be done just before the onset of winter, when all the leaves have already fallen off. Earlier processing can lead to negative consequences, such as burning leaves and untimely dropping.

Among gardeners, the most popular treatment of plants after harvest is 1% Bordeaux liquid.This tool helps to destroy dangerous fungi - pathogens of scab, powdery mildew, rot and other diseases. All fruit trees, berry bushes (including strawberries), as well as perennial ornamental crops are thoroughly sprayed with a special pressure cylinder or spray bottle.

After leaf fall, but no later than the end of October, the crown of bushes and trees and the soil under them are sprayed with a solution of urea (carbamide). This is an excellent prevention of scab and spotting.

Copper sulfate: tips for preparation and use

Eradicating treatment in early spring is necessary for both fruit and ornamental plants. The processing of the garden in spring with copper sulfate or yellow sulfate is carried out during the period called the "green cone" - the buds have already burst and the green color of the foliage is visible. When the leaves unfold, the green cone phase will end.

The duration of the green cone phase depends on the temperature. If warm sunny weather is established (> 20C), plants actively accumulate heat and moisture, the phase passes very quickly. It is better to do the processing a little earlier than to be late.

There are many recipes for different treatments for garden plants in the spring. It is more convenient to carry out 1 treatment that eradicates "in the bud" all diseases and many pests of the garden.

Consider 2 effective ways to treat the garden from pests and diseases.

Iron vitriol is an antiseptic, fungicidal agent that allows you to fight rot, mold, fungal diseases of plants. This preparation is the only fertilizer containing iron in the form available to plants. With an insufficient intake of such a trace element, premature yellowing and dying off of young shoots occurs.

If the plantings are old and they are worried about such problems as the presence of moss and lichen, then the autumn treatment of the garden with iron sulfate with a concentration of 5-7% will help get rid of them. The main difference between the autumn treatment with iron vitriol from the treatment with Bordeaux liquid is that the addition of lime is prohibited.

The effect of the treatment with iron sulfate is much less than that of the previous methods, but there are also advantages - the saturation of trees with iron, and a distinctive effect on oxidation processes.

For the prevention and treatment of certain plant diseases, it is used together with other chemical agents for the complex therapy of plantations. Insecticides can be added to the solution to repel unwanted harmful insects.

Autumn spraying with copper sulfate pursues preventive goals. By the time the buds begin to bloom, the trees will already be protected from disease. A solution of copper sulfate will help prevent fruit rot, powdery mildew and scab.

The drug is considered a fungicide for combating diseases of berry, fruit (pome and stone fruit), ornamental crops. It is a good prophylactic agent against various types of fungal diseases on plants. The concentration of copper sulfate is selected depending on the type of plant. So, for spraying apple and pear trees, as well as quince, it is necessary to make a concentration at the rate of 100 g of the drug per 10 liters of water.

And for stone fruit crops, such as plums, cherries, cherries, as well as peaches and apricots, a different concentration is used - 50-75 g per 10 liters of water. The same concentration is used for spraying berry bushes. Spraying with copper sulfate is best done in the fall, since in the spring a highly concentrated solution will harm young foliage. But this can be done not earlier than November, since a chemical burn is possible when processing the leaves.

Treatment of the garden in autumn with urea

Before processing roses before winter, it is necessary to carry out a number of measures that are necessary so that the plant can survive the winter and bloom next year and delight every site of a self-respecting florist with its beauty. This article focuses on the step-by-step care and treatment of these beautiful flowers to help growers do everything right.

Every summer, the queen of the garden is overgrown with new shoots. It is important that they mature before the onset of frost. If the rose is attacked by a disease, then the leaves are affected and fall, and this is fraught with the fact that photosynthesis will be disrupted. As a result, the bush will not receive enough nutrition, the shoots will not become woody and will freeze in winter. In addition, diseased fallen leaves will become a source of infection the next year if not removed.

To preserve the shoots of climbing roses, it is necessary to fight diseases, otherwise they will not ripen and freeze

In order not to grieve about the roses that died from an infectious burn and about chlorosis in the summer, it is necessary to treat them with iron sulfate before hilling and sheltering the bushes for the winter.

Chlorosis of roses occurs due to iron deficiency

Preparation of a three percent solution of ferrous sulfate:

Dissolve 300 g of ferrous sulfate in 1 liter of soft or rain water. Use only non-metallic cookware.
Pour the solution into a plastic bucket with 9 liters of water in a thin stream, stir.

Note that iron will precipitate in hard water. The bush itself and the ground under it are sprayed. After treatment with this fungicide, the leaves will turn black, this is normal. But it is guaranteed that not a single pathogen will survive until spring. But ideally, all tops should be trimmed and burned before spraying.

Iron vitriol is an old proven remedy that is safe for plants

For rose diseases, I alternately use the fungicides Skor and Ridomil Gold. Thus, it is possible to stop the spread of fungi. For prophylaxis, at the end of June I spray both roses and tomatoes with HOM. It is very convenient if you prepare 10 liters of solution, enough for both.

At first, I covered roses for the winter without treatments with iron vitriol. I noticed that even under a ventilated shelter - lutrasil, the bushes suffer from mold and an infectious burn. Therefore, I believe that it is imperative to spray roses with iron sulfate before frost.

Autumn diseases of roses are suppressed by spraying with fungicides and potassium-phosphorus dressings. If only a few leaves are affected, folk remedies will do. For beginners, so as not to get confused, it is better to use HOM for prevention and treatment. Winter health of thorny pets is guaranteed by treatment with iron vitriol. It burns out any fungi and spores.

It is a highly efficient granulation fertilizer containing in an assimilable form the nutrient nitrogen necessary for plant growth and development. Its mass fraction in fertilizer is 46%. Urea is the most popular spraying agent. It can be used both in autumn and spring. In the autumn, the concentration is taken at the rate of 500-700 grams per 10 liters of water.

When working with urea in the fall, remember:

urea are organic fertilizers, but their composition is determined by mineral nitrogen-containing components;
it is a fast-acting concentrate, the properties of which are maintained for a long period;
fertilizer quickly erodes, therefore it requires irrigation of the soil itself, including greenhouse and greenhouse;
the connection is effective in waterlogged areas;
biologically active soil retains more nitrogen than alkaline or neutral soil media;
nitrogen-containing dressings are more effective and safe for the garden in the autumn, when the foliage does not burn when the concentration is disturbed;
urea slows down the growing season, delaying flowering from spring frosts that are fatal for the ovary.This will have a fruitful effect on the preservation of early ripe varieties of plum, peach and apricot, and the fruit trees themselves preserve the buds that are being formed;
after spraying in the fall, garden pests die, and various diseases of garden crops are eliminated;
after connecting to the ground, carbamide turns into ammonium carbonate;
nitrogen-containing compounds do not accept compounds with chalk, lime and simple superphosphates;
urea helps to get rid of old stumps, provokes their rapid decay;
autumn treatment of the garden with nitrogen concentrate protects garden plants from early frosts.

In the arsenal of the farmer there is a proven, reliable preparation - iron vitriol. It is still in demand despite the emergence of many new chemicals. Reasons for popularity: wide range of applications, low toxicity, affordable price. What kind of drug it is, how to dilute it and then process the garden, we will tell you further.

What is the difference between autumn rose care?

Spring and summer care for roses is aimed at the active growth and development of plants. Autumn care, on the contrary, provides for the inhibition of their vegetation. Why is this necessary? Roses in the fall change their state somewhat:

Stem lignification occurs;
Shoots and buds slow down development;
The root accumulates nutrition and strengthens;
All metabolic processes slow down.

This is how nature prepares rose bushes for frost. How to properly care for roses in the fall? Let's figure it out.

Composition and release form of ferrous sulfate

Iron vitriol is otherwise called ferrous sulfate. From a chemical point of view, it is a salt, ferrous sulfate. It looks like small crystals (sometimes powder) of greenish color with a bluish (turquoise) or yellowish tint.

Copper sulfate (crystals of a deep blue color) is not an analogue or substitute for iron, each has its own recipe and tasks.

Iron vitriol is sold in garden and hardware stores, retail packaging is usually 200 or 250 g. Mass fraction of the useful substance (sulfate) - 53% (grade 1) or 47% (grade 2); in terms of pure iron - 20%.
