Grapes are not only tasty, but also a very healthy berry. The culture is quite whimsical regarding climatic conditions, especially with the onset of spring, since it is weakened after hibernation. Various pathogenic / pathogenic microorganisms have a detrimental effect on the growth and formation of berries. To effectively combat them, growers and summer residents use iron vitriol and its analogues.

What is iron sulfate: general information

Iron sulfate, also known as ferrous sulfate, is one of the most effective compounds that are designed to combat plant diseases and pests. Its benefits are due not only to the suppression of microorganisms, but also to the saturation of the plant with iron. As a result, the bushes are gaining strength and can independently fight the disease. Unfortunately, not all novice agronomists use this composition, but in vain.

Note:in addition to performance, iron vitriol is also available. Its cost is low.

Iron vitriol looks like small green crystals, which is why it is often called green vitriol. For humans, this composition is absolutely harmless. But, despite this, during irrigation of plants it is strongly recommended to use personal protective equipment - glasses, a respirator and rubber gloves. Mature grape bushes need regular irrigation with ferrous sulfate. Thanks to this, it is possible to get rid of lichens and moss, to prevent the development of scab, and also to normalize the processes taking place in the respiratory system of grapes.

Iron vitriol for grapes: benefits

  • The substance stimulates the production of chlorophyll by the plant, due to which the foliage on the trees begins to develop more rapidly, they acquire a rich green color.
  • Provides effective resistance to lichens, mosses and fungal spores.
  • The composition is used as a disinfectant, as well as to eliminate unpleasant odors in cesspools.
  • Added to whitewashing when processing bushes trunks. It has been found that such treatment can compensate for iron deficiency.
Chlorosis of grapes, treatment

If you regularly process grapes with ferrous sulfate, you will be able to achieve the following results:

  • The leaves grow in size and take on a healthy, attractive appearance.
  • On the lateral part of the vine, lateral processes begin to form actively.
  • The bark becomes more elastic.
  • The beneficial effect of the composition on the plant affects the abundance of fruiting. The berries are larger and healthier and more attractive.

Important:it is contraindicated to combine iron vitriol with slaked lime. For these purposes, it is recommended to use copper sulfate.

Rules for the preparation of iron sulfate for processing grapes

How to get rid of wild grapes on the site

Iron vitriol for grapes in early spring is very necessary, therefore, for the first time, the plant must be processed soon after the end of winter. The first spring spraying is carried out before the formation of the first buds.In horticulture and viticulture, the second planned treatment does not occur in the summer, but in the fall, when it is time to prepare for the upcoming wintering. It is necessary to process all grape varieties without exception, otherwise it will not be possible to avoid the disease, and during cold weather the vines can freeze.

Important:it is recommended to spray grapes in spring with iron vitriol with an active substance concentration of no more than 0.5%. For dilution, you will need to observe the following proportions: 50 g of the substance and 10 liters of water at room temperature.

Fungicides for grapes

Correct feeding in autumn is carried out closer to November. At this time, you need to carefully monitor the weather conditions, the first frosts should not be yet. It is necessary to dilute the substance in a completely different way than in the spring.

  • For processing young plants, you must use a 3% solution of vitriol. For 10 liters of water at room temperature, there should be 0.3 kg of fertilizer.
  • Spraying of adult grapes, which has been bearing fruit for more than 1 year, is carried out with a solution of 5% vitriol. For 10 liters of water - 0.5 kg of substance.

All proportions must be strictly observed, otherwise the processing will have a detrimental effect on the state of the culture.

Iron chelate for grapes

By spraying the plants on his backyard, the gardener provides protection from pest attacks and the development of diseases. This is due to the fact that after the composition has dried, leaves, branches, etc. covered with a protective thin film. Thanks to this, the plant does not become infected with fungal and infectious pathologies.

Treatment with iron sulfate in autumn provides excellent protection against cold weather in winter. The formed film warms the plant.

Important:plants treated with vitriol wake up a few weeks later, this is normal.

Late bud opening is due to the presence of a film that always forms after treatment.

When is it better to process: autumn or spring

Many agronomists are convinced that, thanks to the autumn feeding, the plant will not only survive the winter frosts, but also strengthen the vine. Weather conditions are unpredictable and a drop in temperature of 1-2 degrees can destroy the grape bush. It is also worth paying attention to the fact that many diseases may not appear in the fall, but with the onset of spring they will deal a crushing blow to the culture. Soon after waking up, it is dangerous to heal the plant because it is weakened after hibernation. In the vast majority of cases, there is only one outcome - the plant dies.

The development of the bush depends on the conditions in which it overwintered.

Important! No shelter can protect a plant from the attacks of fungal and viral infections. At the first thaw, pathogens begin to destroy the bushes.

Processing can be carried out only after harvesting, all foliage falling off and pruning. All preparatory procedures for wintering must be carried out in a comprehensive manner: pruning, fertilizing under the root collar, irrigation with vitriol and shelter for the winter.

Fertilizers are best applied to the soil in a complex manner, and irrigation should be done strictly in accordance with the age of the shrub. After drying, the bush acquires a dark color, due to which it is possible to timely identify the places affected by the fungus or infection.

Irrigation of grapes

How to properly breed iron vitriol for irrigating grapes:

  • After removing the shelter for irrigation in the spring - 0.5-1% solution of vitriol.
  • To combat disease-causing organisms such as oidium, mildew, etc. - 4-5%.
  • In the fight against lichen and moss - 3%.
  • As a foliar dressing of grapes - 0.1-0.2%.
  • For the treatment of chlorosis - 0.05%.
  • Before covering for the winter, autumn treatment - 3-5%.

Despite the wide variety of chemicals designed to strengthen, prevent and treat diseases, ferrous sulfate still occupies one of the leading places.

Precautions, advantages and disadvantages

The substance belongs to the 3rd hazard class, i.e. low-hazard to humans. It does not spontaneously ignite, does not explode. When a large amount enters the human body, general poisoning, upset of the digestive system and irritation of the skin and mucous membranes are observed. Urgent medical attention is required.

Irrigation must be carried out in calm weather, in personal protective equipment.

Stored in hermetically sealed packaging for an unlimited amount of time. It is advisable to use the open one as soon as possible, protect from dampness.

Advantages of the drug:

  • Non-toxic to humans, plants and animals (in moderate doses).
  • Replenishes iron deficiency.
  • High efficiency against fungi is noted.
  • Long shelf life.
  • Relatively low cost of the drug.

Despite the many advantages, the drug still has a small list of disadvantages.

  • With a decrease in concentration, it does not work.
  • Processing time limits.
  • The formed film is easily washed off by rain.
  • An overestimated concentration of the active substance can leave burns on plants.
  • Efficiency against viral and bacterial diseases is low.

Iron vitriol is a very effective micronutrient fertilizer, which is effective in the prevention and treatment of various diseases and pest attacks. Plants can be saturated by irrigation or by digging into the soil in autumn and spring.

Iron vitriol is justifiably included in the list of the most demanded drugs. When used correctly, it provides good and consistent results. Before use, be sure to read the instructions for use.
