Iron vitriol for grapes: how to breed for processing in summer, autumn and spring

Growing grapes requires knowledge regarding the protection of the plant from disease. Only preventive measures taken in time can lead to the full development of the vine, successful and abundant fruiting. The timely feeding of the berry crop also plays an important role. Gardeners need to use iron sulphate for grapes in agricultural technology. The drug is important as a means of preventing and treating major diseases of the fruit crop.

What is this?

Ferrous sulfate is called a solution of ferrous sulfate. Iron sulphate is odorless and consists of transparent crystals of a bluish-green color. Substance differs:

good solubility in water;
low toxicity;
oxidation by air;
low decomposition at high temperatures.

In industrial production, iron sulfate is obtained as a by-product when iron sheets or wire are etched with sulfuric acid to remove scale.

You can prepare a substance yourself by acting on scrap iron with a dilute solution of sulfuric acid.

The use of iron sulfate is extensive. In addition to agriculture, it is necessary as a medicine for patients with iron deficiency anemia. It also serves as a means for dyeing fabrics, producing ink.

Iron vitriol is produced in the form of a crystalline powder, in bags weighing 150 grams.

Mechanism of action

Since ferrous sulfate crystals are obtained by the action of sulfuric acid on iron, they are used when necessary:

replenish the number of atoms of an important substance in plant tissues;
fertilize the soil;
destroy pathogens;
take action to combat chlorosis.

The crystals contain so much iron that if it is lacking, it can be replenished with 1-2 spraying procedures with a solution.

Given the low toxicity of the substance, it is used only for preventive purposes in the fall. Treated plants will be protected from fungal infections. But vitriol has little effect on insect pests, stronger means are needed. Therefore, copper sulphate, which has stronger disinfectant properties, is useful here.

What are the benefits for grapes

For work in the vineyard, it is necessary to use a solution of iron sulfate. Due to the lack of iron, problems begin in the vine. They are determined by the lag of shoots in growth, yellowing and falling of leaves. There is nothing to dream about the harvest when the vine is in such a state. Only treatment with iron sulphate will save.

For diseases: mildew, bacterial cancer, spotted necrosis - spraying with iron sulfate will also help. They heal wounds on the vine, since the restoration of the structure of the woody layer under the action of vitriol solution is faster.

In the northern regions, you can artificially delay bud break by treating the shoots with ferrous sulfate. Then frosts, which are most dangerous in spring, will not harm the vine.

Experienced gardeners know the effect of a solution of ferrous sulfate as the main remedy that protects against winter cold. The drug helps to stimulate the reproduction of the berry crop.

The tool has many advantages. In addition to a wide range of effects, it is also noted that it has low toxicity. Delicately affecting plants, without penetrating deep into tissues, the drug has a beneficial effect on the growth and fruiting of grapes.

It just needs to be properly bred so as not to burn the vine.

The substance goes well with citric acid. The prepared mixture effectively copes with non-infectious chlorosis. But vitriol is not mixed with lime, since there will be no benefit from such a composition.

Uses

The use of iron sulfate in the vineyard is quite extensive:

Washing the vine shoots will scare away the ants. Pests always damage the vine along with aphids. After spring whitewashing, you can forget about these insects.
Prevention of grape chlorosis is carried out by the method of soil treatment with a solution of ferrous sulfate. Spraying the vines is carried out before the buds open and the first leaves appear, which will avoid a problem during flowering and fruiting.
Processing with ferrous sulfate will save you from the formation of mosses, lichens, and various damages on the shoots of grapes.
Pour the grape bushes under the root with a mixture of 1 tablespoon of citric acid and 2 tea ferrous sulfate, taken in 3 liters of cold boiled water. It is also necessary to feed the leaves of the berry culture with such a composition in order to improve the he alth of the vine. It is important to use the product immediately after preparation, once every 10 days.

Used root dressing of grapes annually, but the concentration of the solution is different in young and adult plants.

Procedure for making ferrous sulfate

Depending on the purpose of processing grapes, the proportions for preparing a solution of ferrous sulfate are different:

Iron in the composition of the powder is necessary for plants in the spring, after the snow melts. Prepare a concentrated solution. 15 grams of the substance is poured into a bucket of soft settled water. After mixing, water the soil on the plantation.
In order to destroy the larvae of pests and spores of pathogenic fungi, you will need to prepare a mixture of 150 grams of the substance by dissolving the powder in 10 liters of water.
The non-standard part of the vine is treated in April with a 3% solution of ferrous sulfate. Only such a concentration of the substance will lead to the destruction of growths in the form of mosses and lichens.
1% iron sulfate remedy is used as a prophylactic after pruning the vine. By whitewashing the stems of grapes, they contribute to the formation of a protective film on them. It will become an obstacle to the penetration of fungi and insect larvae into the plant.

Dilute ferrous sulfate crystals only in soft water. Before the procedure, crystals are poured into rain or well-settled water. Thanks to the ability of vitriol to dissolve quickly, the product will be ready in 20 minutes.

How to use it correctly

Most often, a solution of ferrous sulfate is used during the period, as soon as the snow melts, and the kidneys will still be in a dormant state. In the spring, with the help of a solution, you can:

fertilize the soil in the vineyard;
protect the crop from pests;
disinfect damage on shoots;
to save plantings from mosses, lichens.

Don't cultivate the soil unless it shows signs of iron deficiency.

Insecticidal treatment is carried out with a solution of 0.5-1%. Bred as the instructions say. A strong concentration of the drug will lead to burns of the vine. In the same way, a remedy is prepared to prevent chlorosis in a fruit crop. Water under the root with a mixture. For foliar treatment, a 3% solution of ferrous sulfate is taken.

The same mixture is used to treat places where growths in the form of lichen or moss have appeared. After a few hours, they are scraped off mechanically.

In places where there are wounds, cracks and other damage, carry out with a soft brush, applying a 1% aqueous solution of ferrous sulfate.

Effective processing and in the fall before the shelter of the vine for the winter. It is necessary to prepare the solution more concentrated, from 3 to 5%. After such a procedure, the vine laid for the winter will not grow moldy, it will survive the winter cold well.

In the summer do not use iron sulphate to treat the vineyard, as it causes leaf burns. You can only apply watering with a weak solution of ferrous sulfate when signs of chlorosis are found on the plant.

Common Mistakes

Like any chemical preparation, iron sulfate must be used correctly.

If you violate the instructions for preparing the solution, irreparable things can happen. Plants are threatened with death when the concentration of ferrous sulfate is above the norm.But when using small doses during treatment, the proper result from prevention or treatment should not be expected.

Spraying the buds that are still sleeping can stop their development. This is suitable for regions where spring frosts often return and kill the vine. In the southern regions, after such processing, the development of the kidneys will stop, and the harvest will not be received on time.

Iron vitriol does not cure bacterial infections. It is not worth wasting time on processing, but it is better to replace the drug with copper sulphate, which is more effective against pathogenic microorganisms.

The acidic composition of ferrous sulfate does not allow it to be combined with products based on zinc, copper, magnesium. All alkaline preparations are not used with ferrous sulfate. And laundry soap in solutions is not used. In combination with alkalis, there will be no sense in processing with iron sulphate.It is better to alternate spraying with different preparations, observing a break of 2 weeks.

To process the vines, they take a spray gun or sprayer, protecting parts of the body from contact with the working fluid. On the face - a respirator, hands - in rubber gloves.

Pets should not be near the vineyard during the disinfection process.Wash hands with warm soapy water after applying ferrous sulfate solution.

Given the instability of the drug, carry out disinfection with the drug in quiet cloudy weather. Rains can wash the substance off the vines, and then preventive measures will have to be taken up again.
