People who grow plants in a garden or vegetable garden are familiar with this. effective drug... In most cases, when diseases occur or for prevention, inexperienced farmers prefer various kinds of chemicals and.
But application ferrous sulfate brings a lot more positive results than modern methods fight. At the same time, the effect of the insecticide is less harmful to fruit crops than when using other means.
, designed to fight diseases provoking a fungus, as well as the appearance of moss growths on tree trunks and lichens. The chemical is produced in the form of small granules of a pale green or light green shade with a gray admixture, and is also sold in the form of a loose powder. The product in any form dissolves easily in liquid. The composition of the fungicide consists of a salt (53%), which was formed upon contact of sulfuric acid combined with crystalline hydrate and ferrous iron.
The composition of the fungicide consists of a salt (53%), which was formed upon contact of sulfuric acid combined with crystalline hydrate and ferrous iron.
Insecticide treatment in the first spring months slows down bud opening and inhibits the awakening of the whole plant. Such a process has both positive results under certain weather conditions and a negative effect.
Iron sulfate is often used as a fertilizer, as well as a substance for disinfecting greens and bark of fruit crops. In addition, the drug is used as an insecticide. The diluted consistency of iron sulfate appears from elevated level ... This negatively affects green foliage, if the fungicide is sprayed on young leaf blades, it can cause burns.
Therefore, the procedure for influencing trees and shrubs is carried out only in early spring, until the beginning of the growing season of plants. In addition to the first spring month, the event is allowed to be held in the fall - after the harvest and the complete fall of the foliage.
The first reason why culture is exposed fungal disease - fallen leaves. If it is not removed, spores of fungi begin to develop inside its accumulation, which provoke the disease. Foliage harvested at the wrong time can transfer from the ground to the trunk and branches dangerous diseases... It is recommended both in spring and autumn to disinfect not only the ground part of the plants, but also the soil under them.
It is best to carry out spraying activities in the fall.
Gardeners purchase ferrous sulfate II for use in the following situations:
- For treatment against tree diseases for the spring and autumn period.
- To eliminate pests from branches and bark, as well as their larvae, and eggs laid for the future.
- For watering the plot - many farmers use chemical agent for fertilizing the territory, due to the fact that the drug contributes to the saturation of the soil with iron. Such feeding has a beneficial effect on increasing the growth of plantings.
- While digging the soil, introducing the drug along with humus into the soil.
- For neutralizing scab or black cancer.
- For therapy (real and false), coccomycosis, or gray rot.
- For treatment different colors, including from spotting.
- For preventive measures on.
- For processing sections after pruning, so that pathogenic bacteria or pests do not join the plant.
Iron vitriol is not intended for processing indoor flowers. It is used exclusively to influence fruit cropsposted in open ground... Thus, the insecticide has a wide spectrum of action. It is used not only to eliminate disease-causing bacteria, but also as a growth stimulant into the earth.
So that the drug, instead of good, does not cause even more harm, it is required to precisely maintain the required concentration of the solution. To do this, you need to accurately follow the dosage for diluting the essence.
The following norms are distinguished for the correct effect on various fruit crops:
- To eliminate moss or lichens on the bark of trees, a liquid is used, with a 5% concentration of the drug - 600 g. iron sulfate powder per 10 liters. liquids.
- A solution of ferrous sulfate for pears, requires 4% of the fungicide composition - up to 500 gr. granules of fungicide on a bucket of liquid. In this case, the water consumption should not exceed 10 liters. per 100 m2.
- Stone fruits (,) are irrigated with a 3% solution: 0.3 g is diluted per 10 liters of liquid (a bucket of water). powder. Spraying is carried out in the fall before preparing for winter (shelter), after the foliage has completely fallen off along the bare shoots.
- Disinfection of cellars from various fungal diseases requires a highly concentrated essence - 500 gr. insecticide on a bucket of water.
- As a preventive measure, irrigation is performed with a 1% solution. This requires no more than 150 grams. granules of the drug diluted by 15 liters. liquids.
Other shrubs with a delicate leaf structure need to be further reduced in concentration. This is to avoid burns on the leaves. The spraying event takes place on a warm, windless day. It is best to implement the procedure either in the morning before sunrise, or late in the evening, when the rays of the sun disappeared beyond the horizon.
If the sun is not expected on the scheduled day, and the weather is cloudy, then spraying is performed if there is an exact confidence in the absence of rain in the near future. Otherwise, if precipitation falls, the whole procedure will be in vain.
Thus, while carrying out work to combat diseases and pests, one should be guided by the main rule - not to harm the plant. Therefore, it is better to dilute the required amount of essence with a minimum dosage than to increase the rate and burn the entire foliage to the plant.
Iron sulfate is not as dangerous as copper sulfate. He has level 3 danger. This suggests that the drug is not able to spontaneously ignite or explode without human help.
It is not necessary to wear a protective gown and gloves when handling the substance. The main thing. It is required to ensure that the substance does not get on the mucous membrane of the eyes or oral cavity... In case of contact with any amount of highly concentrated 5% substance on skin person, urgently needs to wash his hands under large quantity running water using laundry soap.
For chemical substances it is recommended to allocate storage space in the garage or utility room... It is believed to use the drug better in autumnthan in the first months of spring. This is due to the fact that foliage has already flown from the trees and shrubs and it cannot be burned, which happens in spring, if the procedure is too late.

Find out from the article how and for what iron sulfate is used in gardening. Read how to prepare a solution of vitriol to fertilize plants.
Ferrous sulfate - by appearance similar to copper sulfate, only differs from it in color. Iron vitriol has a bluish green tint. This salt is obtained by the reaction of the interaction of iron (II) and sulfuric acid. This fungicide has the ability to act only on the surface of plants, without penetrating into its cells. Further details.
Iron vitriol: instructions for use in the garden
The high acidity of the substance causes burns on plant leaves. That is why gardeners recommend using the product in early spring or late autumn, when the leaves fall. In addition, so that fungal infections do not remain below, on the ground, do not forget to process the soil near the plants. Just before the process, remove the fallen leaves around the tree trunks.
The substance is used for:
- Development retardation on fruit trees powdery mildew
- Getting rid of false growing
- Fight against gray mold
- Treatments anthracnose, coccomycosis, clasterosporium diseaseetc.
How to prepare plant treatment solution (concentration):
- To destroy lichens on fruit trees a solution of ferrous sulfate with a concentration of 5-6% is used
- To get rid of fungal diseases, prepare a mixture of 3-4% concentration
IMPORTANT: For processing garden plants calm, dry, cloudy weather is suitable.
Iron vitriol as plant fertilizer
So that the shoots of shrubs and trees do not die off, the leaves do not turn yellow ahead of time, the flowers have a bright color, they use iron vitriol. Thanks to such a substance, garden crops receive the necessary trace element (iron) for their growth and development. A solution of ferrous sulfate can be watered on crops, or the agent is added to manure (100 g of vitriol per 10 kg of compost).
Ferrous sulfate - fertilizer for the garden Iron vitriol: use in viticulture for processing and feeding grapes
Using this tool to vine possible only when there are no leaves on the grapes, that is, in autumn or spring. It is enough to carry out one treatment per year. If you used ferrous sulfate in the spring, then in the fall it is no longer necessary to spray.
Ferrous sulfate solution creates a thin film on the plants after spraying. This ability of this substance use experienced gardeners... In the fall, they process the grapes. The film that forms on the plants protects them from light frosts. Do not be alarmed if in the spring your grapes bloom a little later than the untreated bushes. Two weeks delay is not critical.
IMPORTANT: Treat very young grape bushes with a 1% solution of vitriol, and spray rooted plants with thicker bark with a 3% solution.
Processing apple trees in early spring with iron sulfate
Ferrous sulfate treatment should be carried out when there is no frost outside and the air temperature is set within 5-7 ° C. For this process, 3% ferrous sulfate solution.
This substance contributes not only destruction of various fungal microorganismsand also feeds apple tree important element — iron... Spraying a mixture of water with ferrous sulfate powder itself is also useful in that apple tree growth is stimulated, and happens increased absorption of carbon dioxide... This process has a positive effect on the formation of such needed by plants substances like chlorophyll.
Processing currants with iron vitriol in spring
All garden crops need constant care, only pruned, fertilized and processed plants will please their owner excellent harvest... In early spring, gardeners should start seasonal work.
You should start by trimming dry branches. Then it is necessary to dig in the plant in a circle and fertilize with manure mixed with ferrous sulfate powder (for 10 kg of fertilizer, 100 g of ferrous sulfate).
After these works, the processing of currant branches is done from all kinds of insect pests and fungal diseases. For such procedures, a 1-3% solution of iron sulfate is suitable.
Processing strawberries with iron vitriol in autumn
Many people love this fruit berry. But to grow it you need to make every effort. Strawberries are especially susceptible to fungal infections. These include:
- Powdery mildew
- Gray rot
- Late blight rot
- Mottling
- Late blight wilting
Iron sulfate is an effective means of preventing these plant diseases. It must be applied after the harvest has been harvested. First, feed the strawberries with slurry with the addition of ferrous sulfate. Tear off the leaves, remove the weeds. Treat the bushes of the plant with a 0.3% solution of ferrous sulfate. For the winter from severe frosts cover the strawberries with lutrasil.
Chlorosis treatment on tomatoes with iron sulfate
Tomatoes are sensitive to iron deficiency. Even if the soil contains a normal amount of this substance, chlorosis can still appear in young tomatoes. Outwardly, it is not difficult to determine the disease. Faded appear on the leaves of the plant yellow spots between the veins. And the young leaves become completely yellow, dry.
To eliminate the problem, use a 0.1% iron chelate solution.
Recipe:

One of the most popular means of pest control is ferrous sulfate, the use of this agent in gardening in autumn is no less active than in spring.
Iron vitriol has a crystalline appearance, not transparent, odorless, in chemistry it is defined as ferrous sulfate or ferrous sulfate. With it, you can improve the condition of old trees, as well as increase the fertility of young ones. Usually used diluted in water, but for different types plants need a different concentration.
In what cases is iron sulfate used?
Gardeners often resort to using 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 gets on 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, but also the soil are treated with a solution.
Iron sulfate is also used as whitewashing of plant trunks in preventive and disinfection measures. To do this, you need to dilute 100 g of ferrous sulfate in 1 liter pure water.
Concentration of solutions
There is no single instruction for breeding ferrous sulfate. Experienced gardeners distinguish between different concentrations of solution for different types 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, apples, 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 autumn period as a preventive measure, it is performed 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.
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 increased sensitivity of crops to iron deficiency. To feed the plants, it is necessary to dilute 50 g of ferrous sulfate in 10 liters of water, treat the trunk and soil every 4-5 days until the leaves appear green.
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.
Precautionary measures
Do not confuse ferrous sulfate with copper sulfate, which is more dangerous for the human body. Iron vitriol 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.
Methods of using ferrous sulfate in the garden for processing trees and shrubs.
Iron vitriol is a well-known remedy used by experienced gardeners. Newbies tend to favor pesticides and chemicals as more effective and more reliable. In fact, iron vitriol is not inferior in effectiveness to fashionable drugs, but much safer.
Iron vitriol, use in gardening in spring: instruction
Our grandfathers used this salt very often, as there were not enough chemicals. At the same time, ferrous sulfate is completely safe, unlike pesticides.
How to prepare a 3% solution of ferrous sulfate for spraying trees and plants?
This solution is used to treat tree trunks and shrubs. Processing is carried out after no leaves remain on the trees. That is, in spring and autumn. It can be processed with a brush or sprayer. An excellent tool copes with moss and lichens.
Instructions for the preparation of a 3% solution of ferrous sulfate:
- Take liter jar and fill it with water. It is best to use a measuring glass. You need 1000 ml of water.
- Pour 30 g of ferrous sulfate into the water. If you don't have a scale, throw in about a tablespoon of salt.
- Stir the mixture thoroughly until the crystals are completely dissolved. The liquid will turn orange.
Chlorosis of tomatoes is a common ailment that often occurs when uncontrolled processing of seedlings with potassium permanganate. In addition, deficiency of glands can appear due to poor soil. In this case, the leaves of the seedlings turn yellow and green streaks are visible. To make sure that the culture lacks iron, run a brush dipped in 0.1% ferrous sulfate solution over the leaf. In a day, he will turn green.
Instructions for using ferrous sulfate against chlorosis on tomatoes:
- Take a liter warm water and dissolve in it ½ teaspoon citric acid... Enter a heaping teaspoon of ferrous sulfate. When the crystals of acid and salt dissolve, you can start processing.
- For this, the leaves of the seedlings are sprayed from a spray bottle. So, the iron will work within 24 hours.
- You can water the plants, but iron is absorbed through the roots only after 3 days.
Processing and feeding grapes with iron vitriol in spring: proportions
The processing of grapes with iron sulfate is carried out in autumn and spring. Moreover, the concentration of the solution is different.
Grape processing instructions:
- Dissolve 50 g of ferrous sulfate in 10 liters of water. Processing is carried out in early spring, when there are still no buds and young leaves. Leaf treatment can harm the plant.
- After dissolving the crystals, the vine is sprayed. Liquid can be applied with a brush.
- In the fall, the solution should be stronger. Processing is carried out after harvesting and pruning the grapes.
- Dissolve 300 g of iron salt in 10 l and treat the shoots in the same way.
Processing currants in spring with vitriol will get rid of moss, aphids and lichens.
Ferrous sulfate will help get rid of powdery mildew, gray rot and mites. Spraying of strawberries is carried out in autumn and spring. Two treatments per year are enough.
Instructions:
- Dissolve 300 g of ferrous sulfate in a bucket of water
- Put the solution into a spray bottle and spray the leaves
- Pour the rest of the liquid under the stems
The main advantage of ferrous sulfate is that it not only eliminates pests, but also saturates the plant with iron. Thanks to this, it is possible to strengthen the plant and improve the yield.
Instructions:
- Ferrous sulfate is used in combination with urea. As a result, you will get a highly effective drug against pests and feeding the apple tree.
- Urea solution is used for treatment with the addition of ferrous sulfate at the first spring spraying even before the appearance of the kidneys.
- A weak solution (50 g per 10 l of water) is used to treat the tree a week after flowering.
Iron vitriol - inexpensive and effective remedy from aphids, rot, lichens and moss. It allows you to fight chlorosis.
VIDEO: Iron vitriol in the garden
And pests are impossible. Though modern market proposes a wide range of means for pest control, not all of them are effective, and some quite expensive.
Therefore, many experienced gardeners recommend using long-proven, well-known and budget resources, one of these is iron vitriol . In horticulture, ferrous sulfate is widely used, it is used both for prevention and for the purpose of eliminating many plant diseases, including fungal ones, as well as as protection against insect pests.
What is ferrous sulfate: composition and properties
Iron vitriol, iron sulfate or ferrous sulfate is a salt that is obtained by reacting sulfuric acid and ferrous iron.
At normal room air temperature, the substance looks like turquoise or greenish-yellow small crystals (pentahydrate). The amount of active substances in such crystals is 53%.
When iron sulfate is used
Iron sulfate solution is highly acidic, which is why it can cause burns if sprayed on green leaves. Therefore, the treatment of the garden with iron sulfate must be carried out early or after the leaves fall, in the fall.
In both spring and autumn, the main cause of infection with fungal diseases is the remains of leaves and branches on the surface. Therefore, in the spring, they carry out not only the processing of trees, but also the surface of the earth around them.
In autumn it will be much more effective to collect and burn fallen leaves and plant debris, as well as to dig in trunk circlesbefore you spray the trees.
In horticulture, vitriol is traditionally used in such cases:
- for preventive treatment of cellar walls and vegetable storage areas;
- for treating wounds and processing cuts in trees;
- for treating trees and berry crops against mosses, lichen, scab, etc.;
- for the treatment of spotting;
- for processing ;
- to combat insect pests;
- for the treatment of this and, as well as, coccomycosis,.
Compatibility with other drugs
Ferrous sulfate should not be mixed in the same solution with organophosphate insecticides ("", etc.), as well as with other drugs that decompose in an alkaline environment. Do not mix iron sulfate with lime.
Instructions for use: concentration and consumption rates of ferrous sulfate
It is worth remembering that young trees have significantly thinner bark than adults, so they can only be processed once, in the spring. Adult plants are treated twice: in spring and autumn.
For various purposes, there are certain dosages that must be followed to achieve maximum effect.
Fight against fungal diseases
For the treatment of fungal diseases, a weaker solution of iron sulfate is used, at the rate of 30 g per 10 liters of water. Spraying must be carried out 2-3 times, every 7 days.
Chlorosis
Ferrous sulfate treatment helps fight chlorosis, which can occur in plants due to lack of fertilizers or iron deficiency. To prepare a solution to combat chlorosis, 50 g of ferrous sulfate must be dissolved in 10 liters of water.
Spraying is carried out every 4-5 days until the green color of the leaves is restored. In order to carry out preventive spraying, a lower concentration will be required: 10 g of ferrous sulfate per 10 liters of water.
Against mosses and lichens
Ferrous sulfate will also help get rid of lichens and mosses, which quite often affect old trees. Dosage for processing fruit trees from mosses and lichens: 300 g of ferrous sulfate per 10 liters of water. Pome trees need more concentration - 500 g of ferrous sulfate per 10 liters of water.
Disinfection of trees with ferrous sulfate
For the treatment of wounds, cracks, places where branches are cut, 100 g of ferrous sulfate must be diluted in 10 liters of water and the damaged tissue of trees must be treated with the resulting solution.
Spraying berry crops
Iron vitriol for the protection of berry crops, currants, etc., is used at a dosage of 3%. Spraying is carried out with a solution obtained at the rate of 300 g of iron sulfate per 10 liters of water before starting.
Iron vitriol for sprinkling grapes
Iron vitriol is the main protector for grapes, as it has one peculiarity: it delays bud opening by about a week. 
Therefore, if you treat the culture with a 3-4% solution of ferrous sulfate before the beginning of the growing season, this will help to survive the period of spring frosts and temperature changes. it especially true for grapes, if you carry out its processing 5-7 days after removing the winter shelter.
For the treatment of grapes with iron vitriol, the following dosages are recommended:
- For spring processing after removing the winter shelter - 0.5-1%
- For the destruction of microorganisms and pests such as mildew, oidium, grape pollen, etc. - 4-5%
- From moss and lichen - 3%.
- To combat chlorosis - 0.05%.
- For processing in the fall, before shelter for the winter - 3-5%.
Did you know? In addition to all of the above, with the help of iron sulfate, you can eliminate unpleasant odors in gardens and vegetable gardens due to summer
