But in order for the use of iron sulfate to bring the maximum benefit to the grapes, you need to know how to use it correctly. This will avoid serious mistakes.
Other names for ferrous sulfate – ferrous sulfate, ferrous sulfate
Is it possible to process grapes with iron sulphate
The agent is a crystallized substance with a blue or greenish tint. It contains the trace element iron about 47-53%.
With this tool, it is not only possible, but also necessary to process grapes. After all, it is distinguished by fungicidal and antiseptic properties and at the same time does not cause addiction in pathogenic microflora. This makes it possible to treat the vineyard with iron sulphate several times a season.
Beneficial features:
- suitable for the treatment and prevention of diseases;
- eliminates iron deficiency, which prevents the development of chlorosis;
- strengthens the immune system;
- increases resistance to temperature changes;
- does not accumulate in fruits, soil;
- safe for humans, beneficial insects, animals;
- not phytotoxic.
Why spray grapes with iron sulfate
Regular use of this tool when growing grapes helps to solve many problems. It is suitable for feeding, treatment of wounds and cracks, protection against diseases and spring return frosts, as well as for the control of lichens and moss. But in each case there are some features of its application.
Additional fertilizing
With a lack of iron in the soil, grapes suffer from chlorosis. It is manifested by a light shade of foliage, on which dark veins are clearly visible. In this case, the process of photosynthesis is disrupted, which negatively affects the development of culture. If the disease is not treated, then you should not count on a good harvest.
Iron sulfate helps to fix the problem. But in order to increase the absorption of the missing component by the plant, it is necessary to convert it into a chelate form. In this case, experienced gardeners recommend taking 3 liters of warm water into a container and adding 1 tsp to it. citric acid and 1 tbsp. l. ferrous sulfate, mix thoroughly. After that, water the grapes with a solution.
Against diseases and pests
This tool helps to successfully fight fungal diseases of the culture. In this case, it is recommended to use a highly concentrated solution of 5%. Processing can be carried out before the start of the growing season or at its end.
Iron sulfate is effective against:
- alternariosis;
- clusterosoporiosis;
- black cancer;
- anthracnose;
- coccomycosis;
- scab;
- septoriosis;
- gray rot;
- late blight;
- oidium.
Also, this tool helps to deal with wintering crop pests. For this, it is recommended to use a solution of increased concentration. Spray the vine should be before bud break.

Disinfection of wounds and cracks
After pruning, as well as during temperature changes on the shoots of the plant, the integrity of the bark cover is violated. This increases the likelihood of penetration into open wounds of pathogenic microorganisms. The use of iron sulfate in this case allows you to create a protective film that will help prevent this.
To do this, use a 1% solution of the product. It should be applied with a brush to thoroughly treat problem areas.
Treatment of grape cuttings with iron sulphate
Iron sulphate is also beneficial in the processing of cuttings. Before planting the bushes, it is recommended to spray the upper part of the shoots with a solution of this agent at a concentration of 0,5-1%. This treatment allows you to slow down the process of bud break for two weeks. During this time, the cuttings will be able to form young roots. This allows you to increase the percentage of survival of seedlings and their immunity.
Also, gardeners use this feature of the product to protect the crop from spring return frosts. If there is a threat of a sharp temperature drop, it is recommended to spray the vine in advance. This will prevent kidney damage.
From mosses and lichens
When mosses and lichens appear on the vine, it is also recommended to use iron sulfate. In this case, a 3-5% solution should be applied in early spring or late autumn. Such treatment contributes to the death of growths within three hours after its implementation.
Iron sulfate cannot be combined with lime and copper sulfate
How to dilute iron sulfate for processing grapes
To use iron sulfate for processing grapes, you must first dilute it with warm water in the correct dosage. Depending on the purpose of the application, the concentration of the working fluid may be different.
It is necessary to dilute iron vitriol for processing grapes immediately before use, since the finished product retains activity for no more than six hours.
You can prepare the working fluid in plastic or glassware to prevent a chemical reaction. This product has a high acid content. So that their treatment does not cause burns on the plant, every gardener must know how to properly breed it.
Possible applications:
- 1% solution. To prepare it, you need to dilute 100 g of the component initially in a small amount of water. And then bring the total amount of liquid to 10 liters.
- 3% solution. To prepare a working fluid in such a concentration, it is necessary to dissolve 300 g of the component in 1 liter of water, and then bring its total volume to 10 liters. After this, the product must be thoroughly stirred and insisted for half an hour.
- 5% solution. To prepare the working fluid, dilute 2 g of the substance in 500 liters of warm water, mix thoroughly. Then bring the volume of liquid to 10 liters and leave for 30 minutes.
It is very important to strictly observe the required dosage. Exceeding the concentration of the working solution causes burns of leaves, buds, shoots.
When to spray grapes with iron sulfate
You can use this tool in early spring or late autumn. It is important that the plant has not yet entered the growing season or finished it. Therefore, it is necessary to take into account some features of the processing.
Spraying grapes with iron sulphate in spring
The use of this remedy in early spring is recommended for the treatment and prevention of diseases, protection from frost, inhibition of the development of mosses and lichens, elimination of iron deficiency that causes chlorosis, and protection of the crop from pests.
It is possible to carry out spraying of the vine with this agent at a temperature of + 3-7 ° С
When using ferrous sulfate as a fungicide and insecticide, a solution with a concentration of 3-5% should be used. The resulting product should be treated with a vine in dry calm weather. The solution must be sprayed evenly on the shoots, so that after it dries, a protective film forms on the surface of the bark, which inhibits the growth of fungi and sporulation, as well as the development of pest larvae.
To prevent the development of chlorosis and damage to the kidneys from frost, a solution of ferrous sulfate should be used at a concentration of 0,5-1%. In the first case, you need to not only spray the bark, but also water the plant.
Autumn processing of grapes with iron sulphate before shelter
Processing grapes in the fall is necessary to prepare them for wintering. The procedure helps to increase the immunity of the culture, and also destroys wintering pathogens and pest larvae.
It is recommended to use iron vitriol in autumn after leaf fall, when the grape shoots are completely bare. But at the same time, it is important that the air temperature does not fall to 0 ° C and below. Experienced gardeners recommend processing at the end of October, at the beginning of November, depending on the climatic conditions of the region.
For spraying grapes with ferrous sulfate in the fall, a solution should be prepared in the proportion of 300-500 g per 10 liters of water. At the same time, the concentration for young seedlings should be lower than for adult plants.
Ferrous vitriol is washed away by rain
accident prevention
If iron sulfate is used in accordance with the instructions for use, then it does not pose a danger to human health. However, standard precautions must be followed.
Before preparing a working solution and spraying crops, you need to wear gloves, a mask and goggles, as well as clothes and shoes that cover open areas of the body as much as possible. In case of contact with the skin and mucous membranes, rinse with running water. During the treatment it is forbidden to drink, smoke, eat.
The drug can harm human health if it enters the food tract, which causes poisoning. In this case, you need to take an absorbent and consult a doctor.
Common mistakes
When using iron sulfate, some novice gardeners ignore the rules for its use. As a result, instead of benefit, the remedy harms the culture. This not only negatively affects the yield of grapes, but can also cause its death.
Frequent mistakes:
- Ignoring processing deadlines. You can not spray the grapes with a product after bud break, during the flowering period. This causes burns.
- If it is necessary to use the drug in the summer, the solution should be applied only to the affected areas of the vine.
- Phosphorus-containing agents and other preparations for plant protection can be used only two weeks after treatment with iron sulphate.
- It is necessary to strictly adhere to the dosage indicated in the instructions. Its excess harms the plant and weakens it, and a low concentration is useless.
- It is necessary to spray the grapes in autumn with the preparation only when plant residues on the soil are removed, otherwise the procedure will not give the desired result.
Conclusion
Iron vitriol for grapes is beneficial if used correctly. Therefore, before using the drug, you need to read the instructions. Only in this case, the effectiveness of the product will be maximum, which guarantees a good harvest at the end of the season.
