Iron vitriol for coniferous trees. Ferrous vitriol - use in gardening in the spring for processing fruit trees, as a fertilizer for plants: instructions, breeding proportions. Iron vitriol: characteristics and use

Inexpensive, available remedy with a wide spectrum of action - this is how the owners characterize iron sulfate. The use of ferrous sulfate in horticulture is not only protection against pests: the solution is suitable for disinfecting cellars, cesspools, and mold control.

Many summer residents use ferrous sulfate solutions of various concentrations for autumn and spring processing. fruit trees. good effect gives the use of iron sulphate as a fertilizer. Lot useful information for summer residents - in this article.

Release form

inkstone – chemical compound, greenish powder blue color. The concentration of the active substance is 53%.

Ferrous sulfate II is actively used by gardeners to care for fruit crops, preventive measures, destruction harmful insects. For processing different surfaces the owners prepare a solution of a certain concentration. It is impossible to break the fortress of the composition: possible leaf burn, damage to the bark, at a low concentration, the effect of the procedure weakens.

You can buy iron sulfate in different packaging:

packages of 200 g - price from 10 to 15 rubles;
kraft bags 25, 40 and 50 kg - price from 21 to 37 rubles per kg;
for large farms, the price of a ton of ferrous sulfate is from 3,600 to 5,500 rubles.

Benefit and action

Ferrous sulfate - universal remedy. Unlike the more toxic one, the bluish-green crystalline substance is suitable not only for protecting the garden from pests and diseases, but also for other operations.

Summer residents use a solution of ferrous sulfate in the following cases:

for whitewashing fruit tree trunks in spring/autumn;
for the destruction of harmful insects, with a preventive purpose;
for the treatment of a dangerous disease - spotted roses;
as a remedy for the appearance of hollows and wounds on the bark of trees;
as a valuable fertilizer;
how to destroy house fungus;
for disinfection of walls of vegetable stores, cellars;
to protect grapes from diseases and pests;
for elimination bad smell from country toilets, cesspools;
against scab, mosses, lichens on horticultural crops Oh.

Concentration

How to breed iron sulfate? A positive processing result will be only if the strength of the solution is strictly observed:

treatment of chlorosis - concentration 0.05%;
fight against oidium, mildew - 4 or 5%;
autumn processing of grapes - from 3 to 5%;
fight against lichens, mosses - concentration 3%;
spring treatment of plants after removal protective coating– from 0.5 to 1%;
as a microfertilizer for grapes - from 0.1 to 0.2%, for foliar feeding potatoes, all types of cabbage, tomatoes, the concentration is higher - from 0.5 to 1%;
treatment of wounds, disinfection of hollows, whitewashing of trunks - 10%;
fertilizer for digging along with compost - a concentration of 10% (for 10 kg of organic matter, take 100 g of ferrous sulfate);
treatment of raspberry bushes, currants - the concentration of the solution is 2.5%;
during the growing season, the solution is not stronger than 1%, after dropping the leaves - 5%;
prevention of scab, black cancer, septoria - a strong remedy, the concentration of the solution is 5%;
destruction of house fungus - 15%, for whitewashing the walls of cellars, storages with grain, a 6% solution is needed;
fight with black spot on roses - a rather weak solution, the concentration is 0.3%.

On a note! In the spring, spraying is carried out in mid-April, when the air and soil warmed up, the pests woke up and had time to lay their eggs. Autumn processing begins after the foliage is shed. Interseasonal spraying is the prevention of the penetration of dangerous pests.

Advantages

Ferrous sulfate in the form of a crystalline powder has many advantages:

a wide range of activities;
protection of many horticultural crops, vine from diseases and pests;
the benefits of spring / autumn processing of the garden, greenhouses, gardens;
active fungicidal properties: destruction of the fungus on the walls of basements, granaries;
ease of preparation of the working solution: iron sulfate II must be dissolved in water, and the composition is ready for use;
long shelf life of crystals without loss useful properties;
iron is in the composition of sulfate in a form easily accessible to fruit trees, vegetables, shrubs;
with the right concentration of the solution - a rather delicate effect on plants;
the working solution is suitable for spraying vegetable, fruit, berry crops;
good disinfectant country toilet, cesspool;
iron sulfate is actively used for fertilizing various crops;
manufacturers offer different weights of packages and bags with ferrous sulfate for summer residents and large farms;
the cost of iron sulfate is quite acceptable compared to some types protective equipment and fertilizers.

disadvantages

Like any gardening agent, ferrous sulfate II has disadvantages:

for different types plants, disinfection, pest control, as a microfertilizer, for processing in autumn and spring, its own concentration of the working solution is required. An incorrect dosage of green-blue crystals per liter of water worsens the result, often provokes leaf damage or does not give a noticeable effect from the procedure;
water easily washes away particles of the substance, you need to wait until dry, windless, cloudy weather is established;
ferrous sulfate does not destroy pests wintering in the soil or tree bark. Late application of the solution harms the future crop and the tree itself.

Application in horticulture against pests

Ferrous sulfate solution effective remedy for the destruction of dangerous insects that damage fruit and berry and vegetable crops. With careful spraying of trees, almost half of the individuals of the apple sucker die, damaging many plants. Often, after spraying, not only adult insects die, but also larvae, eggs laid by pests.

Iron vitriol destroys:

codling moth;
leaf beetles;
sawflies.

On a note! The gardener must focus not only on the calendar, but also on the temperature of the air and soil. At early processing pests sleep on trees and soil, there are no egg-laying, time and money wasted in vain. With late spraying of pears, plums, apple trees, fruit trees may be damaged, and pests wintering in the bark will continue to winter.

Iron vitriol protects plants in the garden from many dangerous diseases:

downy and true powdery mildew;
black spot;
septoria;
scab;
gray rot;
spotty necrosis;
black cancer;
anthracnose;
clasterosporiasis.

Mosses and lichens rarely settle on fruit trees and shrubs treated with ferrous sulfate. When undesirable organisms appear on the trunks, a 3% concentration of ferrous sulfate solution will cleanse the plants of growths. When spraying, spray the product not only on plants, but also on the ground. Green leaves cannot be treated with an active compound: burns are possible.

iron sulphate as a fertilizer

The good availability of the active substance in the composition of ferrous sulfate explains the active use of vitriol solution for feeding many vegetable crops, fruit trees.

For foliar feeding, dissolve 5–10 g active agent in a small amount of water, bring the volume to 10 liters. This method is suitable for fertilizing tomatoes, potatoes, cabbage. A good option- combine 10 kg of compost with 100 g of vitriol crystals to fertilize plants in the garden.

Helpful Hints:

from iron sulfate it is easy to get quite expensive and effective remedy- iron chelate. For 10 liters of water you will need 2 tbsp. l. citric acid. After the crystals are completely dissolved, add ferrous sulfate - 1 tablespoon;
it is forbidden to mix bluish-green powder with lime. When iron and calcium come into contact, compounds are formed that plants in the garden do not absorb well. Perfect option- prepare a working solution in soft water.

Mold use

Ferrous sulfate is an inexpensive, effective remedy for eliminating granaries, basements. The toxic effect is minimal, the mold leaves the treated surfaces well.

Application Features:

you will need a solution of vitriol of medium concentration: for 10 liters a little warm water take 100 g of bluish-green crystals;
for ease of application, pour a little clay into a bucket with a prepared product for a more viscous consistency;
walk along the walls of the cellar or granary with a brush, carefully process all areas;
the optimal time for mold prevention is autumn;
processing is carried out twice, after the procedure, ventilate the cellar well.

Mold control, prevention of fungal infections, spraying of plants should be carried out in protective clothing. Be sure to wear a respirator rubber gloves, protective plastic glasses, make sure that the liquid does not get on the hands or eye area. Iron vitriol is less toxic than copper sulfate, but care must be taken. If liquid comes into contact with eyes or skin, rinse immediately running water. In case of severe irritation, visit a dermatologist or optometrist.

People involved in growing plants in a garden or garden are intimately familiar with this effective drug. In most cases, when diseases occur or for prevention, inexperienced farmers prefer various kinds chemicals and.

But the use of iron sulfate brings a lot more positive results than modern methods struggle. At the same time, the impact of the insecticide causes less harm to fruit crops than when using other means.

, designed to fight diseases that provoke a fungus, as well as the occurrence 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 impurity, and is also sold in the form of a friable powder. The agent in any form is easily soluble in liquid.
The composition of the fungicide consists of a salt (53%), which was formed by the contact of sulfuric acid, combined with crystalline hydrate and ferrous iron.

Insecticide treatment in the first spring months provokes a slowdown in bud break and inhibits the awakening of the entire plant. Such a process has positive results under certain weather conditions, as well as a negative effect.

Iron sulfate is often used as a fertilizer, as well as a substance for disinfecting greenery and bark. fruit crops. In addition, the drug is used as an insecticide. The diluted consistency of iron sulphate acts with increased level. This negatively affects green foliage if the fungicide is sprayed on young leaf blades, - may cause burns.

Therefore, the procedure for influencing trees and shrubs is carried out only in early spring, before the start of the vegetation of plants. In addition to the first spring month, the event is allowed to be held in the fall - after the harvest and complete fall of the leaves.

The first reason why culture is exposed fungal disease- fallen leaves. If it is not removed, fungal spores begin to develop inside its clusters, which provoke the disease. Inopportunely collected foliage is able to 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 of 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 irrigation of the site - many farmers use a chemical agent to fertilize the territory, due to the fact that the drug contributes to the saturation of the soil with iron. Such top dressing has a beneficial effect on increasing the growth of plantings.
While digging the soil, introducing the drug along with humus into the soil.
To neutralize scab or black cancer.
For therapy (real and false), coccomycosis, or gray rot.
For treatment various colors, including 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 for influencing fruit crops placed in open field. Thus, the insecticide has a wide spectrum of action. It is used not only to eliminate pathogenic bacteria, but also as a growth stimulator inside the earth.

So that the drug does not cause even more harm instead of good, it is required to accurately maintain the required concentration of the solution. To do this, you need to accurately follow the dosage for diluting the essence.

The following standards are distinguished for the correct impact 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 gr. iron sulphate powder per 10 liters. liquids.
A solution of ferrous sulfate for pears, requires 4% of the composition of the fungicide - up to 500 gr. fungicide granules 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 done in the fall before preparing for winter (shelter), after the leaves have 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 carried out with a 1% solution. This requires no more than 150 gr. granules of the drug diluted by 15 liters. liquids.

Other shrubs with a delicate structure of the leaf blade need an even greater decrease in the concentration of the solution. This is necessary to avoid burns on the leaves. The spraying event is held 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 luminary disappeared beyond the horizon.

If the sun is not expected on the scheduled day, and the weather is cloudy, then spraying is carried out if there is an exact certainty that there will be no rain in the near future. Otherwise, if precipitation falls, the whole procedure will be in vain.

Thus, during the work to combat diseases and pests, one should be guided by the main rule - do not 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 leaf cover of the plant.

Iron sulfate is not as dangerous as copper sulfate. He has a 3rd level of danger. This suggests that the drug is not capable of self-ignition or explosion without human assistance.

During interaction with the substance, it is not necessary to wear a protective gown and gloves. The main thing. It is required to ensure that the substance does not get on the mucous membrane of the eyes or mouth. In the event that any amount of a highly concentrated 5% substance gets on the skin of a person, it is urgently necessary to wash your hands under large quantity running water with laundry soap.

For chemical substances it is recommended to allocate storage space in the garage or utility room. It is believed that the use of the drug better in autumn than in the first months of spring. This is due to the fact that foliage has already flown from trees and shrubs and it cannot be burned, which happens in the spring if the procedure is carried out late.

For normal growth and development of plants need to monitor their health. Iron sulfate is often used not only for treatment, but also for disinfection of plants. You can read about what kind of substance it is and how to use it in one case or another in the article below.

What is iron sulfate?

ferrous sulfate

Before studying the use of a substance in horticulture, you must first find out what it is. Iron sulfate is ferrous sulfate. It is obtained by the reaction of the interaction of ferrous iron and sulfuric acid. Iron sulphate is blue-green crystals that dissolve very easily in water.

Unlike copper sulfate, which has blue crystals, iron sulfate has blue-green crystals. It is by color that these two drugs are distinguished on the market at the time of purchase or immediately before use.

The use of iron sulfate in horticulture is the most diverse. So, for what purpose is the drug suitable?

For the treatment of fungal diseases on shrubs and trees.
For the treatment of vineyards from oidium, anthracnose and gray rot.
To combat spotting on roses.
For disinfection of pagon cuts and twigs on shrubs and trees.

Iron vitriol is one of the few drugs that are completely safe for plants. It has a 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 storages for vegetables, fruits, disinfection of boxes, garden tools.
For the destruction of lichens and mosses.
Like fertilizer in the field.

Dilutions of iron sulphate

Any drug should be used according to the instructions. Iron sulfate is no exception. If you dilute it incorrectly, the plant may die or deteriorate. So, how to dilute the drug correctly?

The breeding container must be absolutely clean. If previously used for chemicals then you need to wash it well.
The container is suitable for plastic or glass. Metal containers should not be used, because they will simply deteriorate.
The solution is stirred 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 sulfate to help in solving the problem, and not to harm, it must be used in the correct dosage. So, in the case of pest control and their larvae, it is necessary to spray the trees (shrubs) and near-stem circles in the spring, before the buds open.

Processing of young shrubs and trees is carried out blue vitriol only once a year.

It is necessary to use a solution at a concentration of 5%. In other words, 500 g of sulfate is taken per 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 strong remedy from lichens and mosses, which can lead to damage to bushes and trees in the garden. How do you take off the 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 off 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. Bleach this mixture and damaged twigs to disinfect them.

The use of iron sulphate

Iron vitriol treats many fungal diseases. In this case, a concentration of 3% is used. For plants, a preparation is prepared according to the following recipe: 10 liters of water, 300 g of iron sulfate. After mixing, you need to carry out 2-3 treatments with a break of a week.

The dangerous disease chlorosis is also treated by spraying with iron sulphate. 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 to process grapes?

For grapes, iron is a very important mineral, so this particular crop needs regular treatment with iron sulphate. It is applied either by spraying or under the root during irrigation. So before processing grapes, you need to decide what it is for.

Foliar top dressing allows you to treat the culture from diseases or maintain its strength at certain points in development.

In early spring a 1% solution is used to strengthen the vine.
In the case of fighting fungal diseases, it is worth treating the culture with a 4-5% solution.
Autumn processing involves spraying with 3-5% liquid.

Interesting!

If the vine is treated with iron sulfate in early spring, the buds will bloom a week later. Thanks to this simple method, you can avoid freezing during the spring return frosts.

Root top dressing is carried out along with watering. It is used when the vine lacks iron. 10-15 g of iron sulfate is 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 vegetation of the trees begins, and also 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 culture from diseases and maintains its strength.

In addition, if the tree has been cut, it is also desirable to treat all cut points with iron sulphate. For 10 liters of water, 100 g of ferrous sulfate is used. The cuts are smeared with the substance and left to dry.

Fertilizer Chelate

Not every gardener knows what can be made from iron sulfate good fertilizer- chelate. Its peculiarity is in stimulating photosynthesis in plants. It is done in the following way. Boil 3 liters of water, then cool and dilute 1 tablespoon of citric acid. After that, you can add 2 teaspoons of iron 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 many different applications. This tool can be the best assistant to the gardener, if you use it correctly, remember how to dilute and always maintain concentration.

To increase the yield of vegetables and fruit and berry trees gardeners have to regularly deal with pests and various diseases both in spring and autumn. Many use industrial chemicals that are harmful to the human body, but there are many safe and proven methods by our grandfathers, because there was no way before. chemicals. For example, iron sulfate. Its use is quite effective, and it is not at all harmful. Ease of use gives it another plus. It is an excellent fungicide. Application in horticulture is based on unique properties in the fight against bacteria, fungi, viruses and other sores of trees and bushes, which are not inferior to the properties of chemicals.

The easiest way to get a beautiful front lawn
Of course, you have seen the perfect lawn in the movies, on the alley, and perhaps on the neighbor's lawn. Those who have ever tried to grow a green area in their area will no doubt say that this is a huge job. The lawn requires careful planting, care, fertilization, watering. However, only inexperienced gardeners think so, professionals have long known about the innovative tool - liquid turf AquaGrazz.

Ferrous sulphate, as well as ferrous sulfate, are all different names for ordinary vitriol. It is a salt of sulfuric acid. Appearance- crystals of blue color with a slight greenish tint. Not to be confused with blue vitriol - it has large crystals blue. It is highly soluble in water. The areas of application are varied: chemical industry, metallurgy, energy, fungicide, reducing agent. The melting point reaches 400 degrees.

The chemical formula is Fe2SO4 x nH2O.

Quality standard: GOST 6981-94.

iron sulphate in agriculture mainly used for soil reclamation, pest control and various diseases trees and bushes, as a fertilizer (it is an excellent catalyst for the formation of chlorophyll). In addition, it is used in the manufacture building materials, in the production of batteries and many other industries.

Ferrous sulfate, although not combustible, is explosive. When working with it, safety precautions must be observed.

Thanks to its excellent reducing properties, it makes it possible to refine gold. This is the process of obtaining high-grade gold and other non-ferrous metals. Simply put, it helps to cleanse them of various impurities. This refining method can be carried out independently at home.

What is it used for in gardening?

Vitriol in horticulture is the most universal fertilizer, which is able to effectively restore old trees and increase productivity, fight various harmful insects and diseases of plants and trees. Perhaps there is not a single nasty thing that he could not cope with. It is considered a popular remedy among gardeners with extensive experience, but it is not used by beginners and amateurs, they prefer industrial chemicals. However, ferrous sulfate still remains the most affordable and proven remedy. This is one of the fertilizers that can give any plant iron in the most accessible form. In particular, iron is necessary for the root system to improve respiratory function. Especially old trees need such top dressing.

It is necessary to carefully nourish the soil with the help of vitriol. Dig up its crystals along with compost during the autumn digging. During the winter, the soil will be saturated with iron and will be able to give it to plants. Frequent lack of it occurs in bushes, and roses are highly dependent on the amount of iron in the soil. They demand careful care and more than other plants need this element. Iron sulphate is a great helper in the garden. They can be easily used at home.

Vitriol crystals contain about 50% iron trace elements. Currants and gooseberries simply cannot develop properly without this fertilizer. It has excellent fungicidal properties and is an assistant in the fight against plant diseases, and the treatment of grapes with this solution will save it from many diseases.

Iron vitriol, unlike copper, has a wider spectrum of action and is less toxic to humans. This element fights harmful insects, relieves fungal diseases, scab, lichens and other diseases. It can treat cuts and wounds of trees, and is widely used as a fertilizer. It is sold as a crystalline powder with an unlimited shelf life without losing its beneficial properties. It must be stored in a dry place.

Application methods

At correct use vitriol from iron at home significantly increases fruiting, pest control becomes more effective. Despite its availability and low cost, it is an indispensable tool for gardeners. After its application, scab damage decreases, disappears fruit rot, leaf spot of strawberries and raspberry bushes, anthracnose of currant bushes, rust completely disappears. With regular use, the affected tree bark becomes smooth, and pale leaves saturated with natural in green. Processing should be done both in spring and autumn.

Instruction

During autumn and spring digging, apply the mixture along with compost to the soil. 1 kg of this fertilizer per 100 kg of compost. This will help enrich the soil with iron, which is necessary for the respiration of the root system of plants. All fruit and berry trees need it.
To disinfect wounds on trees and shrubs, you need special solution. Iron crystals (100 grams) diluted in 1 liter of water. Treat all damage with this mixture. This solution is also suitable for whitewashing trees in autumn period. It is advisable to do this from mid-October to mid-November. This type of autumn processing will prevent the development of fungal diseases.
From scab and black crayfish, a 7-8% solution is used. Take an eight-liter bucket of water and dilute 600 grams of vitriol in it. Trees are carefully sprayed with this solution. This procedure is carried out in the fall after harvest. In early spring, until the buds have blossomed, make 1 treatment with a 1% solution.
For the usual treatment of shrubs, it is necessary to dilute 250 grams of vitriol in 10 liters of water and spray the plants. To fight apple sucker need a 3% solution.
Small islands of moss are harbingers of lichen. Such sores are treated with a mixture of 5% vitriol and ash extract. It is necessary to coat the trunks with this in the fall, when all the leaves have fallen. This method is considered the best for lichen and moss.

Also, solutions from vitriol can be used to process cellars and basements. Treating the walls with a weak solution will get rid of unpleasant odors and mold.

Not to be confused with blue vitriol! It is strictly forbidden to mix iron crystals with slaked lime. Treatment with such a solution can lead to disease and further death of fruit and berry plants and grapes.

Application in viticulture

Autumn processing should be carried out regularly. Doing this is easy. Again, vitriol will help with this. It disinfects branches, kills fungus and mold, destroys other harmful insects. This procedure is carried out late autumn after full leaf fall of grapes. 500 grams of iron powder is stirred until completely dissolved in water. Next, carefully spray each trunk of grapes.

When spraying, wear protective gloves and a mask - this will help protect your skin from unwanted contact with the solution. Although vitriol is not very harmful to humans, protection of the skin and respiratory tract is still necessary. This treatment is especially important if the garden is not young. Old trees and shrubs require more careful care, because over a long period of time, great amount diseases, the soil was depleted. Processing will help get rid of lichens, cytosporosis, moss, black cancer and tree scab.

To improve the quality of whitewash, add a little sulfate to the solution - this will be an excellent remedy for fungal diseases of grapes. Spring treatment with a weak solution will be a good prevention of iron deficiency. With regular and proper processing all your vines will get a beautiful and smooth bark, it will become more elastic. Already next spring the leaves will acquire a healthy color and become much larger in size. Accordingly, more shoots will grow, the yield will increase. The clusters will become larger, and the berries will look beautiful.

Precautionary measures

Iron powder is diluted only with water. To do this, you can only use containers made of plastic or glass. Under no circumstances should you use metal utensils. When working with powder and solution, safety precautions must be observed. Be sure to wear a respirator and rubber gloves. If the substance comes into contact with the skin, it should be washed with plenty of water. Although the powder is safe for humans, do not neglect protective equipment.

Using such an agent in the form of fertilizer or medicinal product for plants, you will be able to breathe into your garden new life extending the flowering period of crops.

Is the use of ferrous sulfate in horticulture justified at a time when the market is littered with a wide variety of chemicals for treating and fertilizing horticultural crops? This question is often asked by inexperienced summer residents, because manufacturers of modern drugs present their products as a miracle cure for pests, a panacea for plant diseases or super fertilizer. What harm chemicals can do to a garden, advertising, however, is silent. Often questioned and their effectiveness.

Show all

Beneficial features

Experienced gardeners prefer to use compositions based on time-tested substances, including ferrous sulfate, in the fight for the health of ornamental and fruit crops: the use of many of them does not pose a threat to the human body, plants or animals.

Ferrous sulfate can be used as:

fertilizer;
means for disinfection;
insecticide and fungicide.

Summer residents buy it:

for processing trees in spring and autumn;
destruction of harmful insects, their eggs and larvae;
fight against fungal infections of plants;
treatment of wounds on their trunks;
elimination of iron deficiency in soil and plants;
disinfection of premises for storage of crops.

You can list the diseases that iron sulfate solution protects horticultural crops from:

gray rot;
true and downy mildew;
scab of pears and apples;
grape oidium;
clasterosporiosis;
coccomycosis;
anthracnose;
alternariosis, etc.

It's no secret that toilets in many garden plots are arranged above cesspools. Eliminating the unpleasant odor from them is another function that ferrous sulfate copes with.

How to apply the remedy?

This is a substance with low toxicity, however, the treatment of plants, soil, cellars, etc. with ferrous sulfate should be carried out with precautions. Before spraying, put on:

goggles and a respirator (preferably a shield-mask that will protect the entire face from splashes);
headdress;
gloves;
tightly fastened overalls;
closed shoes.

Although ferrous sulfate is a relatively harmless chemical, it can still irritate the mucous membranes and skin. The substance is washed off with running water. If the burning sensation after rinsing does not go away, you should consult a doctor. After spraying with iron sulphate, you need to wash.

The use of ferrous sulfate in horticulture does not preclude the use of other drugs, but vitriol cannot be bred together:

with organophosphorus compounds (karbofos, etc.),
alkali-resistant substances;
lime.

Copper sulphate (copper sulfate) is mixed with the latter to obtain Bordeaux mixture. Ferrous sulfate, reacting with lime, forms compounds that plant cells cannot absorb, however, iron sulfate can sometimes be used as a component of an autumn protective whitewash for trunks (lime is not included in some whitewash compositions).

The gardener needs to be aware of the shortcomings of iron sulfate. He:

helpless against bacterial diseases;
can cause burns on leaves and young shoots;
valid for no more than 2 weeks;
does not penetrate deep into plant tissue.

Experts recommend treating plants, alternating spraying with ferrous sulfate with their treatment with copper sulphate (Oxyhom, Hom, Bordeaux mixture, etc.). In spring, it is preferable to use preparations based on copper, and in autumn - iron sulfate.

Why is this change desirable? spring processing trees with iron sulphate not only threatens to burn delicate plant tissues, but can also delay bud break. By the way, autumn processing horticultural crops are carried out after the release of plants from foliage.

About the concentration of solutions

So that the use of ferrous sulfate does not harm the plants, it is necessary to strictly observe the dosage of the components in the preparation of the drug. The most concentrated solutions are used to disinfect cellars. To combat lichen and moss on the bark, compounds of 5% concentration are used. The same compositions are processed paving slabs. A solution with a sulfate concentration of 4% is suitable for quince, grapes, pears, apple trees and other pome fruits. With the compositions of 3% concentration of vitriol, stone fruits can be processed:

cherry plum;
apricot;
cherry;
peaches;
plum;
cherry.

For more delicate shrubs, even less concentrated solutions are used. Water with a minimum amount of iron sulphate, in order to avoid burns, leaves and shoots affected by the disease or pests are sprayed.

Spraying with iron sulphate should be done on a calm day. The gardener will have to look at the weather forecast so as not to process the plants just before the rainfall: iron sulfate, which does not have penetrating power and is easily soluble, will simply be washed away by rainwater.

How to work with iron sulphate will more accurately tell the instructions that will be given below.

Iron sulphate against diseases

Considered a lack of composition, the ability to delay the start of the growing season, some summer residents, especially those involved in viticulture, turn it into dignity. The delay in bud break after spraying with iron sulphate is about a week. In the spring, they process bare branches or vines with it, which helps plants survive frosts without damage.

Grape processing

Grapes of covering varieties, for example, are sprayed 7-8 days after the vine is removed from the shelter. For processing, a 3-4% solution is used. In autumn, you can prepare a composition with a concentration of 5%. Spraying them is done after the foliage has fallen.

Vine growers use iron sulphate when planting a plant. They treat the aerial part of the cuttings with a 0.5% solution to stop its development, and the root part not covered by it begins to actively form. The cuttings sprayed in this way are more viable.

It is important for grapes that there is enough iron in the soil. To eliminate its deficiency, the land under the vineyard is fed with a solution with a vitriol concentration of 0.1-0.2% (1-2 g of the chemical per 1 liter of water). If chlorosis has developed as a result of Fe-deficiency of the soil, it is treated by spraying the leaves with a 0.5% mixture.

Iron vitriol can be useful for roses, more precisely for their treatment of black spot. Bushes are sprayed with a 0.3% mixture. The treatment will not save diseased leaves, but spotting on the rose will not return within 2-3 years after treatment. Spraying is carried out once a week until the plant recovers.

ferrous sulfate fertilizer

It is worth returning to the topic of iron deficiency in the soil. Its deficiency negatively affects the state of not only grapes, but also other crops, including vegetables. Due to iron deficiency, the foliage of plants turns yellow and falls off prematurely. Their shoots, flowers and fruits do not develop properly, and root system degrades. Most of all, Fe-deficiency affects the condition respiratory system stone fruit and pome crops: apple trees, cherries, etc. Roses and raspberry bushes suffer from it.

Iron vitriol in horticulture plays the role of restoring the balance of the element in the fertile layer. The substance can be introduced into it during autumn digging. The chemical is mixed with compost in a ratio of 1:100.

From iron sulfate, you can make a chelate - a fertilizer that stimulates photosynthesis. Homemade chelate will cost the gardener much cheaper than store-bought. At home, it is prepared in two ways:

1. In 3 liters of cold boiled water, dissolve 1 tbsp. l. citric acid. About 2 tsp are added to them. sulfate. After mixing the components, the solution will turn light orange.
2. 1 tsp ferrous sulfate is diluted in 0.5 liters of cold boiled water. 10 g of ascorbic acid are added to them (a pure preparation is used, without glucose, etc.). The resulting solution is diluted in 3 liters of water.

Boiling water before preparing the chelate is due to the need to soften it as much as possible.

Vitriol disinfection

Iron sulphate is used in horticulture to treat tree wounds, disinfect trunks and hollows.

In order for the vitriol to disinfect more effectively, before processing it is necessary to clean the trunk of lichen and moss, remove exfoliating sections of the bark from it. The procedure is carried out so as not to injure the healthy tissues of the tree trunk. Rough gloves or washcloths made of synthetic twine, scrapers or spatulas are used in the work. Remove dirt from cracks by carefully scraping them off. plastic strip or sharpened wood chips. Everything that was cleaned from the trunk must be collected and burned.

Iron vitriol must be diluted in concentration, appropriate kind processed plant. The solution is sprayed on the trunks and skeletal branches. After treatment with sulfate, the trunks are covered with whitewash, and the wounds and hollows are sealed. special formulations(for example, garden pitch). You can heal them with a 1% solution of ferrous sulfate.

Some gardeners do not like to remove moss and lichen mechanically. They spray the trees and wait for the colonies to die after being treated with the chemical. Spraying is carried out twice with a 14-day break.

Another way to deal with lichens is to whitewash the trunk with a 5% solution of vitriol in an aqueous extract. wood ash.The extract is prepared in the following proportions:

1 cup of ash pour 3 liters of boiling water;
insist in a closed container for 3 days;
filter;
add another 9 liters of water.

Together with plants, it is desirable to treat with sulfate and wooden structures plot - greenhouse frames, arbors, pergolas, garden beds, etc. A solution of 4% concentration is suitable for spraying them. garden paths moss is removed from the tiles by treating them three times within a month with a 5% mixture.

The harvest collected on the site is stored in cellars and cellars. In these areas, there is a high probability of the formation of fungus. Iron sulfate is one of the tools that destroy mold and prevent its appearance on wooden surfaces. It is desirable to process the cellars annually in the summer. They are washed with a solution with a 10% concentration of sulfate. Sometimes clay is added to the composition for disinfecting wood. In this case, it is better rubbed into the surface and also covers up cracks in the boards.

Ants fight

Whitewashing the lower part of the plant with a solution of ferrous sulfate will prevent ants from appearing on it. For the whole season, it will protect the tree from insects guarding aphids, which, under their supervision, will not fail to ruin both the plant and the crop.
