For normal growth and development of plants, you need to monitor their health. inkstone it is often used not only for treatment, but also for disinfection of plants. What kind of substance it is and how to use it in this or that case can be read below in the article.
What is ferrous sulfate?
Ferrous sulfate
Before you study the use of a substance in horticulture, you must first find out what it is. Ferrous sulfate is ferrous sulfate. It is obtained by the reaction of the interaction of ferrous iron and sulfuric acid. Iron vitriol is a blue-green crystal that dissolves very easily in water.
Unlike copper sulfate having blue crystals, vitriol has blue-green crystals. It is by color that these two drugs are distinguished on the market when they are purchased or immediately before use.

The use of ferrous sulfate in gardening is very diverse. So, for what purposes is the drug suitable?
- For the treatment of fungal diseases on shrubs and trees.
- For the treatment of vineyards against powdery mildew, anthracnose and gray rot.
- To combat rose blotchiness.
- For disinfection of places where pagon and twigs are cut on shrubs and trees.
Iron vitriol is one of the few drugs that are completely safe for plants. It is of contact action, which means that the substance penetrates into the intercellular structure of the plant without accumulating in it.
- For the destruction of pests.
- For processing storage facilities for vegetables, fruits, disinfection of boxes, garden tools.
- For the destruction of lichens and mosses.
- As fertilizer on the site.
Dilution of ferrous sulfate
You need to use any drug according to the instructions. Iron vitriol is no exception. If diluted incorrectly, the plant may die or deteriorate. So, how to dilute the drug correctly?
- The dilution container must be completely clean. If previously it was used for chemicals, then you need to wash it thoroughly.
- The container is suitable for plastic or glass. Metal containers cannot be applied, because they will simply deteriorate.
- The solution is mixed slowly and thoroughly. It also does not hurt to let it brew so that the crystals dissolve well, and then mix again.
- Any manipulations are carried out strictly with gloves.
Pest control
In order for iron vitriol to help in solving the problem, and not harm, it must be used in correct dosage... So, in the case of pest control and their larvae, it is necessary to spray trees (shrubs) and near-stem circles in the spring, before the buds bloom.
Young shrubs and trees are treated with copper sulfate only once a year.
You need to use a solution at a concentration of 5%. In other words, 500 g of sulfate is taken for 10 liters of water. Such processing is carried out 2 times a year - once in the spring and the second in the fall.
How to deal with lichens and mosses?
Lichen control
Iron sulfate is a powerful remedy for lichens and mosses that can damage bushes and trees in your garden. How to take off to fight? Shrubs and stone fruit trees in this case, they are treated with a 3% solution of ferrous sulfate, and pome fruits - 5%. Spraying is carried out 2 times with a break of 2 weeks, first in spring and then in autumn. During these two times, moss and lichen completely fall from the bark.
If lichen and moss very often infect crops, it is worth regularly whitening the plants with a special mixture in autumn or spring. It is made from a 5% solution of ferrous sulfate and a small amount of ash. Damaged branches are also whitened with this mixture to disinfect them.
The use of ferrous sulfate
Iron sulfate is treated by many fungal diseases... This uses a concentration of 3%. For plants, a preparation is prepared according to this recipe: 10 liters of water, 300 g of ferrous sulfate. After mixing, you need to carry out 2-3 treatments with a break a week.
Chlorosis, a dangerous disease, is also treated by spraying with iron sulfate. To prepare the solution, you need to mix 10 liters of water and 50 g of vitriol. Processing is carried out several times with a break of 5-7 days. It is important that the leaves of the plant regain their natural, green color. In the case when chlorosis regularly affects plants, it is worth carrying out preventive spraying weekly. For this, a weak solution is used - 10 g / 10 liters of water.
How do you handle grapes?
For grapes, iron is a very important mineral, so this particular culture needs regular processing with iron vitriol. It is introduced either by spraying or under the root during watering. So before processing grapes, you need to decide what it is for.
Foliar dressing allows you to treat the culture from diseases or to maintain its strength at certain points of development.
- In early spring, a 1% solution is used to strengthen the vine.
- In the case of combating fungal diseases, it is worth treating the culture with a 4-5% solution.
- Autumn processing involves spraying with 3-5% liquid.
Interesting!
If in early spring treat the vine with ferrous sulfate, the buds will bloom a week later. Thanks to this simple method, freezing can be avoided during spring return frosts.
Root feeding is carried out together with watering. It is used when the vine lacks iron. 10-15 g of ferrous sulfate are poured into a 10 liter bucket, stirred and poured into the root zone.
How to handle trees and shrubs?
Spraying trees
In the spring, before the start of the growing season of trees, as well as in the fall, after the end of the growing season, it is recommended to treat the plants with a 3% solution of ferrous sulfate. For shrubs, a concentration of 1% is used. Such spraying protects the crop from diseases and maintains its strength.
In addition, if the tree was cut, it is advisable to also process all the cuts with iron sulfate. For 10 liters of water, 100 g of ferrous sulfate is used. Sections are lubricated with a substance and left to dry.
Fertilizer Chelate
Not every gardener knows what can be made from iron sulphate good fertilizer- chelate. Its peculiarity is to stimulate photosynthesis in plants. It is done as follows. 3 liters of water is boiled, then cooled and diluted with 1 tablespoon citric acid... After that, you can add 2 teaspoons of ferrous sulfate. The color of the resulting mass should be light orange. Fertilizer is used no later than 2 hours after preparation, several times throughout the season.
Iron vitriol is very useful and has a lot different applications... This tool can become best helper gardener, if used correctly, remember how to breed and always maintain concentration.
Iron vitriol (ferrous sulfate) is 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 vitriol 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 making Bordeaux mixture.
Advantages
On sale you can find great amount preparations to protect the garden from fungus and pests. They all differ in composition and mechanism of action. Compared to analogues, ferrous sulfate has several advantages:
- affordable price;
- the ability to apply for different types crops in the garden and vegetable 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 inside plant cells and cannot accumulate in their greens or fruits.
However, there are also a few disadvantages to consider when purchasing it. This substance has a short duration 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 greens.
When to process?
Iron sulfate treatments are well tolerated by plants if carried out on schedule. Only 2 spraying is allowed per year, when there are no leaves on the trees yet. In contact with green parts, the drug causes chemical burns.
In the spring
The first processing of the garden is carried out in early spring, immediately after warming. By this time, the trees should not yet have young leaves or open 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 for insects and fungus.
Advice! For young trees, one spraying in early spring will be sufficient. For an adult garden, additional autumn processing is carried out.
In 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 hibernate in the bark of trees. This drug is effective in autumn. 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 ferrous 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 effect 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 area. 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 found both directly on plants and on their dry residues and on the soil surface. Regardless of the time of garden processing, it is worthwhile to first 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 up the soil in the near-trunk circle.
To work with iron sulfate, you need a spray bottle. In addition, you need to prepare containers for the preparation of the solution in advance. Granules are allowed to be diluted in a 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 dilute correctly
To prepare the solution, it is necessary to measure the right amount powder, place it in a container and pour warm water... Many gardeners recommend using no big amount hot water(for better dissolution of crystals), and then bring the liquid to the desired volume. Concentration active substance in solution will differ:
- 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 up 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 making mixtures. It is not compatible with lime, insecticides and other substances.
Safety engineering
Iron sulfate is classified as a low hazard substance. However, during the preparation of the working solution and spraying the garden, it is necessary to follow the safety rules:
- prepare working solutions exclusively in glass or plastic containers(metal is not used);
- wear thick rubber gloves to protect the skin of your hands;
- dilution of the drug and spraying are carried out exclusively with a respirator or with a protective bandage.
In case of accidental contact with the skin, the likelihood of chemical burns is low. However, it is worth rinsing the skin under running water and monitoring its reaction for several hours. Redness may form on the mucous membranes, but it quickly disappears if the drug is removed with water in time.
From pests and diseases
Iron vitriol is a fungicide, that is, the main purpose of its use is protection against fungal microflora. However, it also has little effect on insects and their larvae, bacterial infection and other pests.
Fruit trees
Fungus on trees is manifested by blackening of leaves or fruits, as well as the appearance of spots and formations on their surface different sizes... 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 fungus once a year, in early spring, and for adults, 2 planned treatments are required.
Solution for fruit trees and berry bushes prepares the same way. The only difference is that due to the thick bark of mature fruit trees, you will need to take dry matter in a higher concentration. It can help you 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 are treated not only with raspberry or currant bushes, but also roses and other shrubs. The drug is effective if it is sprayed over the area twice a year after preliminary cleaning. It acts against a number of diseases caused by a fungus:
- powdery mildew;
- anthracnose (often seen in gooseberries, raspberries, currants);
- white spot of leaves;
- columnar rust;
- black and gray rot.
The ferrous sulfate solution is popular for the treatment of vineyards. It is used at a concentration of 2-3% twice a year. With its help, it is possible to cure and prevent such fungal diseases of grapes as Mildew (downy mildew), powdery mildew, Alternaria, black, white and gray rot.
Processing features
It is necessary to carry out two planned treatments per year. Each of them has its own goals and characteristics. The spraying time depends on the schedule for waking up 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 signs of a fungal infection appear on them during the year, you will need additional processing in high concentration.
In the 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. In the fall, the fungus on the trees was destroyed, and during the winter it could not develop.
In autumn
A few weeks before the frost, the last gardening of the year is carried out. Autumn works include digging up the soil with the introduction of a stock of fertilizers, as well as mechanical cleaning and pest control.
The solution can be used in 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 the warming in the spring. It will quickly be washed off by rains and snow, but during frosts, the fungal flora will be inactive.
Conclusion
Iron vitriol is one of the most popular and budgetary fungicides for gardening. It acts against many types of fungal infections, while being safe for humans. The procedures are carried out according to a specific schedule, which depends on the temperature regime.
Iron sulfate is a fungicide used to combat moss, lichen and other plant diseases. It contains sulfuric acid in its composition, therefore, if used incorrectly, instead of benefit, it can harm the culture. To avoid negative consequences, you need to prepare the concentrate strictly according to the instructions. Trees and bushes are treated only before bud break or after leaves fall, except for those cases when the concentration of the substance in the solution is minimal. The tool belongs to toxic drugs, therefore it is used in the garden, in the fresh air.
- anthracnose;
- gray rot;
- alternaria;
- coccomycosis;
- scab;
- clusterosoporia;
- powdery mildew of a false form;
- oidium grapes;
- real powdery mildew.
- 1.3% solution is used to treat stone fruit crops such as apricots, plums, cherries, sweet cherries, cherry plums and others. Add 300 g of ferrous sulfate powder to 10 liters of water. Spray on bare bushes and trees before sheltering them for the winter.
- 2. 4% or 5% drug is used in the processing of pome varieties: apple, pear, chokeberry, quince, grapes. A ten-liter bucket requires about 400-500 g of ferrous sulfate. 10-15 liters of solution is enough for 100 sq. m.
- 3. To remove mosses and lichens from trees and garden tiles, use a more aggressive concentration: 5-6%. This solution also helps in killing mold in cellars and basements. Dissolve 500 or 600 g of the finished product in 10 liters of water.
- too strong a concentrate can destroy the deciduous part of the tree and bush;
- a solution of less than 1% is ineffective in the fight against diseases;
- rapid oxidation of the drug contributes to the loss of fungicidal properties;
- the period of protective action is rather short;
- there is a certain risk in spring processing.
- 1. During the digging of the garden in the spring and autumn, the agent is introduced together with the compost into the soil in proportions of 1: 100. The procedure helps to enrich the soil with iron, which is necessary for the development of the plant's root system.
- 2. For the treatment of wounds on the bark of trees, use a special solution prepared from 100 g of the drug per 1 liter of water. With the same concentration, you can whitewash the trunks in the fall before the onset of winter. Such a solution is also used to prevent the formation of mold, lichens, and moss.
- 3. To remove black crayfish and scab, a 7-8% solution is required. 600 g of ferrous sulfate salt is added to 8 liters of water. Dissolve the drug by stirring thoroughly. Spray trees in the fall, after harvest.
- 4. For currants and raspberries, prepare a solution by diluting 250 g of products in 10 liters of water. To combat copperhead, a 3% liquid is required.
- 5. Moss and lichens are removed with 5% vitriol and ash extraction. Cover the trunks of trees and bushes in late autumn, after they are completely exposed.

Description
Ferrous sulfate (or, in other words, ferrous sulfate) is a fungicide used to protect garden crops from fungal diseases, destroy lichens and mosses on trees and bushes. It is formed by the interaction of ferrous iron and sulfuric acid associated with water molecules - crystal hydrate. It is 53% salt in the form of granules or powder of light green or gray-green color. The substance is readily soluble in water.
The mechanism of action is contact. The plant treated with iron vitriol is protected for a period of about two weeks.
The product can be stored indefinitely, but the product easily absorbs moisture, so it is stored in a tightly closed glass or plastic container and in a dry place.
Indications for use
The drug has wide range actions and is used by gardeners to protect fruit and berry crops from many diseases:
Ferrous sulfate is practically not used in indoor plant growing. Trees and bushes are processed strictly in spring and autumn. They should be sprayed before bud break or after leaf fall. The branches must be completely bare.
Vitriol is not used as a fertilizer and is not used to treat leaf infections, since the agent burns the green mass due to its high acidity. A 3-5% solution has a fairly high pH: 3-5.
Consumption rates
In horticulture, different concentrations of vitriol are used:
In the absence of scales, you can determine the amount of the drug per eye. A 2% solution is prepared in this way: half a tablespoon of the product is taken per liter of water, as a result of which a bright orange liquid is obtained.
The fungicide delays bud opening by 5-6 days. Having treated the trees with a 3-4% solution, you can wait out the dangerous spring frosts. This is especially beneficial for grapes, as it is an extremely thermophilic plant. Early blooming buds can leave the gardener without a crop, since the grapes freeze when low temperatures.
disadvantages
Along with the advantages of ferrous sulfate, there are also disadvantages. Among them, the following are distinguished:
The substance is harmful to human body, therefore, you should remember about personal protective equipment.
Efficiency
Spring processing delays the development of culture, and this, depending on the weather, is considered both a plus and a minus.
The effectiveness of this agent as a fungicide is questionable, since surface spraying does not completely get rid of fungi. Spores remain behind the bark and in inaccessible places, which multiply after processing. Therefore, grapes and valuable varieties fruit trees it is better to process it with copper sulfate in the spring, and in the fall to give preference to ferrous sulfate.
It must be remembered that ferrous sulfate cannot be combined with certain agents, for example, insecticides containing phosphorus, or substances that decompose in an alkaline environment. Also, do not mix the drug with lime.
Toxicity
Ferrous sulfate has a 3rd class of hazard to humans. Also damages bees and insects.
The concentrate acquires phytotoxicity already at a dilution of 1%. The high acidity eats away at the thin cover of plants, while trees and bushes can withstand the action of a 6% solution. But if you increase the proportions, then they will die from the aggressive effects of the drug.
Processing methods
You can use the following instructions for use in horticulture:
Plants are treated with a brush or sprayer. To prepare a 3% solution of ferrous sulfate, you need to dilute 30 g of ferrous sulfate (1 tbsp. L.) In 1 liter of water. You should get liquid orange.
Fight chlorosis on tomatoes
With an overdose of potassium permanganate, chlorosis develops in tomatoes. Also, the disease occurs when growing tomatoes on depleted soil. Affected tomato leaves turn yellow. For processing, use a 0.1% solution of ferrous sulfate, which is applied with a brush on a leaf. After a day, the affected areas should turn green.
Indispensable helpers to gardeners in the fight for a healthy and bountiful harvest become fertilizers and fungicides. Along with modern expensive means, there is an undeservedly forgotten budget drug, iron vitriol, which has a destructive effect for numerous microorganisms, and at the same time heals plants. Being a contact substance, it does not accumulate in cells, carefully protecting from pests, saturates the soil with iron, bringing invaluable help to plants.
Iron plays one of the leading roles in oxidative and energy metabolism in cells, in the formation of chlorophyll, in the respiratory system of plants. The use of ferrous sulfate in horticulture on saline, calcareous soils, where iron is not absorbed by plants due to a pH of 7 or more, an excess of calcium, phosphorus, magnesium and other antagonists is necessary condition, since ferrous sulfate is the only concentrated source of iron that can give the plant a trace element in an easily accessible form.
In gardening, ferrous sulfate or 53% ferrous sulfate (crystalline greenish powder) has a wide range of possibilities. It is used mainly in the form of aqueous solutions for root and foliar feeding a certain concentration and in an unchanged form for composting.
Purposes of application and norms:
- Prevention of fungal diseases. Produced by spraying soil, trees and bushes (1-3% solution: 100-300 g / 10 l).
- Treatment of fungal diseases: scab, powdery mildew, spot, gray mold and others by repeated spraying, since the protective period lasts up to 10-14 days (3-5% solution: 300-500 g / 10 l).
- Prevention and treatment of non-infectious chlorosis - yellowing of leaves from a lack of iron: watering the soil with solutions of low concentration and multiple spraying of the leaves with a prepared composition with the addition of citric acid (iron chelate) until the color is restored (0.01-0.05% solution: 1-5 g / 3 l).
- Destruction of insect pests and their larvae: apple sucker, aphid, moth, cabbage scoop, leaf beetle, slugs and others by spraying the soil, bark of branches, trunks (500 g / 10 l).
- Getting rid of moss and lichens, the real punishment of shady, moist corners of the garden and old trees. Garden trees, shrubs are sprayed, paths, stones, the lawn is watered (400-500 g / 10 l).
- Disinfection of wounds, cracks in the bark and treatment of hollows in the trunks (100 g per 1 liter of water).
The interest of owners of household plots is caused by the property of ferrous sulfate to disinfect cesspools and places common use several times more effective than bleach without causing damage environment, odorless and cheaper than similar modern biological products.
Can be used to remove mold from concrete and wooden bases basements and cellars, decoration of wooden structures.
What plants can be fertilized with iron sulfate
Iron is necessary for all plants without exception for full growth and fruiting. Potatoes, cabbage, corn, tomatoes, grapes, legumes, fruit, citrus and ornamental plants.
Evidence of iron starvation (chlorosis) is the young leaves of the tops of the shoots that lighten to a lemon color. Older ones turn yellow-brown in the presence of bright green central and lateral veins, followed by drying, as well as deformed, undeveloped shoots and crumbling ovaries. It is possible to correct the situation by spraying the leaves with a 0.05-0.1% aqueous solution of ferrous sulfate (5-10 g of powder per 10 l of water) with a break of 5-7 days or with a chelated form of iron (with the addition of citric acid to the solution), where iron is more stable and assimilated by plants faster and more efficiently.
Such irrigation can also be carried out for preventive purposes, for example, chlorotic manifestations are possible on tomato bushes and with a sufficient amount of iron in the soil, but drought or high humidity at high temperatures, excess lime or ash with unnecessary feeding does not allow the bushes to assimilate it. Potato tubers treated before planting will be protected from scab. Adding 100 g of vitriol to the compost (10 kg) or per 1 m2 during digging will improve the structure of the soil and increase the yield.
In no case do not exceed the dosage of the substance - due to the increased acidity of ferrous sulfate, the leaves and stems will receive significant burns up to the death of the plant.
Instructions for use
Possessing a versatile effect, iron vitriol is used in different concentrations as a monopreparation or combined with citric acid or ascorbic acid (improvised iron chelate).
How to dilute the drug?
For the preparation of the solution, glass or plastic containers are used, since upon contact with metal, the effectiveness of the substance decreases.
Water is used only soft: rain or thawed. Gently pour out required amount powder into water and stir with a wooden or plastic spatula until the crystals are completely dissolved.
In the absence of scales, you can measure the required amount of vitriol using a teaspoon containing:
- 5 g of ferrous sulfate;
- 8 g citric acid.
A tablespoon - 20 g of ferrous sulfate, 80 ml glass, filled to the top, contains 100 g of vitriol.
Self-preparation of a solution close to iron chelate.
With citric acid:
- Dissolve 8 g of citric acid in 1 liter of soft water using a non-metallic spatula;
- add 5 g of ferrous sulfate.
Add another 2 liters of water to the resulting solution. When the ingredients are completely dissolved, an orange liquid is obtained with a concentration of 0.5% iron (II) sulfate. It is necessary to use the drug immediately.
With ascorbic acid.
For 3 liters of water:
- 5 g of ferrous sulfate;
- 10 g of ascorbic acid.
The mixture is prepared according to the principle of the first recipe. Important vitamin C must be clean, free of glucose and other additives. Considering the rapid oxidation of iron, use the composition immediately.
Such a chylate complex does not leave harmful compounds upon decomposition, it is used for the treatment and prevention of chlorosis, but when using solutions of pure iron sulfate, it is important to remember that violation of the instructions for the use of ferrous sulfate entails inevitable consequences: small doses will not have the expected effect, large doses will cause irreparable harm ...
How to spray and water?
Treatment of the garden with iron sulfate is carried out in calm dry weather, taking into account the weather forecast for the next few days, as it is unstable and washed away by rain. When the solution dries, a tightening film is formed, under which spores of fungi, larvae and eggs of insect pests die. This film is soluble, therefore, over time, it is washed off by dew and rain. For greater effect, re-treatment is required after 10-14 days. The area to be sprayed should cover the tops of trees, branches of bushes, and the soil below them.
Treatment of cracks, wounds, hollows, mossy areas and painting of trunks is done with a brush.
Do not mix whitewash with lime, karbofos, copper sulfate and similar substances - healing effect disappears, compounds dangerous for the plant appear.
Soil acidification, its saturation with iron can be combined with watering, the concentration of the solution is 5% (500 g / 10 l).
Nuances of processing in spring, autumn
Correct use of ferrous sulfate significantly increases fruiting and taste qualities fruit, healthy flowering ornamental plants and flowers.
The main condition for the safety of processing the garden with concentrated iron vitriol is spraying only dormant buds, that is, before the sap flow begins in the spring or until it stops completely in the fall.
Spring application stops the development of growth buds, creating a tightening film, for about 2 weeks, which allows vine(4%), fruit trees: stone fruit (3%), pome fruit (5%), rose bushes (3%) and other sensitive plants painlessly survive the cold period.
Spraying is carried out in early spring, after harvesting the remaining remnants of leaves, branches, grass. Pests and larvae that overwintered in cracks in the bark and soil will disappear, saturation of the soil with iron (3%) will save strawberries, raspberries, currants from worst enemy- spotting and other fungal infections. But iron sulfate will not save from bacterial diseases, unlike copper sulfate, with which it will be possible to process the garden only after 1.5-2 months. That's why experienced gardeners the garden is treated with iron sulfate in the fall, and in the spring they are sprayed with copper sulfate.
Trees are treated with iron vitriol in the fall on bare shoots, before the winter shelter of the bushes, after harvesting the leaves.
Compatibility with other dressings
In view of the acidity of ferrous sulfate (pH 3, 5), it is not recommended to mix it with alkaline reaction preparations, with solutions of calcium, boron, zinc, copper, magnesium. By attaching laundry soap for adhesion to the surface, its reaction must be neutral. Neglecting the recommendations, you can best case do not get the expected result in the worst harm to the plant.
Precautions for use
Iron vitriol belongs to the III hazard class, respectively, it is necessary to protect skin and mucous membranes of the eyes and respiratory tract from direct contact irritating effect: gloves, overalls, respirator, headgear.
Before using the substance, free the area from the presence of pets. After using the drug, wash the skin with soap and water.
In case of contact with the skin and mucous membranes of the eyes - rinse with plenty of running water, inside - take a sorbent, consult a doctor.
Iron vitriol is a popular drug among gardeners, which performs protective functions, saturates the soil with iron, allowing you to save money on new plant specimens.
Inkstone. An irreplaceable fertilizer. Instruction.Iron vitriol (or as it is also called ferrous sulfate) is one single fertilizer from many preparations for the garden and vegetable garden, which contains iron, which is necessary for the normal growth of many trees, shrubs, vegetable crops... Iron deficiency leads to a decrease in yield, poor fruit development, and poor plant growth. The use of iron sulfide will relieve the plant of chlorosis, which usually occurs due to improper and plentiful feeding... Vitriol is used to repel pests, and also has a good effect on getting rid of mosses and fungi.
This tool has a fairly wide range of uses. It is used in gardens, vegetable gardens, as well as at home for indoor plants.
Iron vitriol and its properties
· As a fertilizer for improved plant nutrition.
· Pest control.
· Solution for spraying plants.
· Chemical soil reclamation.
Elimination unpleasant odors in country toilets.
· Coloring of wood.
· Fungus of the walls.
· Whitewashing the basement.
This fertilizer is produced in powder form. turquoise that has no expiration date.
Iron vitriol application.
Plants are taken care of with this tool by foliar feeding. During the period of active growth, it is made one percent, after the fall of the foliage - five percent. After 2 weeks, the procedure is usually repeated. With the help of its application, not only the fruiting will increase, but also the neglected fruit trees... Two treatments per year, in spring and autumn, are enough to maintain stable plant growth and replenish iron. Moss and lichen, when applied over the summer, disappear, and the next year the bark becomes elastic.
Such processing is very effective for increasing the amount of the crop. During the spring and autumn digging you can add a preparation for soil dressing (about 100 grams per square meter).
How to dissolve iron vitriol depends on what it needs to be used for:
· 5 grams: top dressing by spraying.
· 30 grams per 10 liters: black spot on roses.
· 0.3 kg per 10 liters: processing of stone fruits and berries, wood coloring.
· 0.5 kg per 10 liters of water: whitewashing of walls, treatment of wood wounds, treatment against mosses, black grape cancer, whitewashing and disinfection of trees.
· 1.5 kg per 10 liters: fungus of the walls of the house.
As a fertilizer, it has tightening properties, as a result of which, after drying, a bud forms on the plant, this is especially good if the garden is located in an area where there are late frosts. With the help of vitriol, the buds appear a couple of weeks later, which makes it possible not to freeze the plant and strengthen the roots, thereby improving the development of the seedling.
It can only be stored undiluted. When working, you should follow the safety rules. The drug can only be diluted in glass or plastic containers. If the solution accidentally gets into the eyes, rinse them with running water to avoid burns to the cornea of the eye.
This agent is successfully used to rid plants of chlorosis, which occurs due to a lack of iron in fertilizers or an excess of lime or ash, as well as bacteria or viruses. A clear sign of chlorosis is yellowing and falling leaves, dying off of roots, and a sluggish state of the plant.
