The use of fungicides makes it possible to protect plants in the garden and garden from bacteria and fungi. Many of the tools that were used before are still being used. Consider the composition, pros and cons of ferrous sulfate, purpose and methods of application. What are its differences from copper sulfate, the compatibility of the product, how to store and substitute fungicides.

What it is

Ferrous sulfate also has other chemical names: ferrous sulfate or ferrous sulfate. It looks like a small size crystals of blue with green color, with a metallic taste, there is no smell. Chemical formula - FeSO4. Crystals dissolve well in water; for better dissolution, they must be diluted in heated water.

Advantages and disadvantages

Iron vitriol has the following advantages:

  • has a strong disinfectant effect;
  • preventive and curative agent;
  • has a detrimental effect on pests;
  • can be used as a fertilizer, as it contains a lot of iron in elemental form;
  • the substance does not penetrate into plant tissues, therefore it does not accumulate in them, it is safe for greens and fruits;
  • affordable and cheap.

Cons of Ferrous Sulfate:

  • the solution is easily washed off with watering and rain;
  • can be used on dormant plants when there are no leaves on them;
  • has some toxicity to humans.

So that the drug does not reduce its effectiveness, it is important to follow the rules for working with it, for example, do not process trees before rain.

What is iron vitriol needed for in gardening

They treat trees and bushes from infectious damage and pests.

From disease

Vitriol is used for infections, lichens and mosses on fruit, shrubs and vines. Prevents infection and heals damage, so they are treated with cuts of branches after pruning, cracks in the bark, hollows.

Iron sulfate has one more effect on plants: it can delay bud opening for about a week, this property can be used to postpone bud opening during the frost period. Trees and grapes in this case are sprayed with a 3-4% solution.

Used to cultivate iron deficient land. The element in the substance is in a form that plants absorb very well.

From pests

Iron sulfate is also used in the garden against pests that winter, hiding under the bark and in the soil of the trunk circles. The bark is also processed in spring or autumn. Often it is mixed with lime, which enhances the fungicidal effect and improves the adhesion of the solution to the bark. The same solution can be used to disinfect wooden elements of buildings, walls of cellars, utility rooms, cattle sheds and sheds for animals.

What is the difference from copper sulfate?

Iron and copper sulfate, although they are salts of sulfuric acid, contain different elements - iron and copper, so their effect on plants is different. But they also have a lot in common - sulfates are used primarily as antifungal agents for treating plants during the dormant period. They can be fertilizers for feeding plants with iron and copper. Each has its own purpose, it will not work to replace one with another as fertilizer.

How to use ferrous sulfate correctly

According to the instructions for use, solutions of different concentrations are used:

  • 3% (300 g per 10 l) - for treating stone fruits from fungi in the fall, before wintering;
  • 4-5% (400-500 g per 10 l) - for pome fruits;
  • 5-6% - for the treatment of trunks and branches from lichens and mosses, cellars from mold.

Expert opinion

Zarechny Maxim Valerievich

Agronomist with 12 years of experience. Our best summer cottage expert.

The fungicidal effect lasts at least 2 weeks after fungal treatment. Treating lichens and mosses may need to be done 1 or 2 more times to reliably eradicate them. During the growing season, green leaves are not treated - there is a high probability that burns will form on them.

The plants are fed with a 1-1.5% solution with signs of iron starvation. The solution is applied by the usual watering method, in spring and summer. For spraying on the leaves, prepare a solution of 0.5%. After foliar application, iron quickly penetrates into the plant, so this method can be used to quickly resolve the issue of element deficiency in the soil. Spraying with iron can be carried out not only for trees, but also for annual crops. Vitriol can be added to compost to enrich it with iron (100 g per 10 kg mass).

Precautions

When preparing the solution, you need to use non-metallic dishes, ordinary buckets will not work. Metal and vitriol react with each other, the solution becomes unusable, the walls of the bucket deteriorate.

Iron sulfate belongs to the 3rd class for humans in terms of toxicity. To work in the garden with iron sulfate, you need to wear gloves on your hands so that the skin is not damaged by powder or solution. Eyes must be protected with goggles and a respirator must be worn. If the liquid does get on the skin, it must be washed off with clean water. Failure to do so may result in severe skin irritation.

With the penetration of aerosol into the respiratory system, liquid into the stomach, poisoning is possible. The effect of the substance is expressed in irritation of the mucous membranes, signs of intoxication, diarrhea. If such symptoms are observed, gastric lavage should be carried out quickly: drink medical charcoal and 1 liter of water. If after this the condition has not stabilized, you should consult a doctor.

Compatibility with other drugs

Iron vitriol should not be mixed in a solution with FOS and agro-agents that decompose under the action of alkalis. Therefore, in spring and autumn, it must be used separately from fungicidal preparations, do not mix them in the same solution. If necessary, treatment with another fungicide must be maintained at an interval of 2 weeks.

In other cases, if vitriol needs to be used in a tank mixture, you should know that theoretically it has good miscibility, but in each case, you should first check the chemical compatibility of the substances. It is necessary to conduct a test: take both drugs in a small amount and combine the solutions in a separate container. If they don't interact, they can be mixed and used.

Terms and conditions of storage

Vitriol can absorb water, so it must be protected from dampness. Store only in tightly closed, undamaged packages so that moisture and air and sunlight do not penetrate the substance. If the conditions are met, the drug can be stored indefinitely. If the packaging is damaged and moisture penetrates, the powder is saturated with water, cakes and partially loses its valuable properties.

The vitriol should not come into contact with food products, animal feed, medicines and household products. It is impossible that iron sulfate could be found by children or animals. Any pesticides and fertilizers can be stacked with vitriol, they do not affect the fungicide and do not change its properties.

Analogs

As a fungicide with a similar effect, you can take copper sulfate or Bordeaux mixture, as well as ready-made preparations "Horus", "Clean Trunk".

As a fertilizer, instead of vitriol, you can use iron-containing preparations, for example, iron chelate, as well as complex micronutrient fertilizers containing this element.

Iron sulfate is a substance that is often used for spring and autumn treatments of orchards and vineyards from a number of fungal infections. Moreover, it finds application both in agriculture and in private. The drug acts quickly and effectively, prevents or treats fungi, destroys mosses and lichens.

It can also be used as an iron-containing fertilizer, especially if it is necessary to quickly restore the amount of an element in the soil. In this case, you can apply the solution under the root or by spraying on the leaf. The normalization of iron levels allows plants to develop steadily, increases yields, and improves the quality of fruits. It does not accumulate in the fruits themselves, so they remain usable. The tool is not expensive, it is stored for a long time, you can buy it at any hardware store.
