Processing apple trees with iron vitriol

For the full development of garden trees and a good harvest, they are sprayed with antiseptic compounds. For this purpose, iron sulfate is used; you can buy it in a special store. It is important to know how to use the drug correctly so as not to harm the garden.

Correct treatment of apple trees with ferrous sulfate makes it possible to fight various diseases of fruit trees. This drug is active used in gardening... This tool destroys moths, ticks, scab, helps from other pests.

Iron vitriol is an iron sulfate, it is afraid of aphids, bugs. The powder prevents the appearance of fungal diseases. It destroys mosses, lichens, covering the trunks. Helps deal with powdery mildew and fruit rot. With its help, apple trees are treated for black cancer.

This tool is gardeners actively used when spraying grapes, but also in the area where apple trees grow, its use is appropriate... Iron sulfate, in addition to destroying pests, also serves as a supplier of iron. Thanks to him, the soil in garden plots is saturated with this useful trace element. For preventive purposes, apple orchards are recommended to be treated with iron sulfate in dry weather, when there is no wind.

Green spaces must be processed before the kidneys awaken. This is due to the fact that the drug is capable of burning young leaves and buds, which is fraught with the loss of part of the crop. The demand for ferrous sulfate is explained by its effectiveness and affordable cost. If lichens, fungal diseases appear on the apple trees, the trees have been attacked by insect pests, this remedy will help. It is indispensable in the fight against pathologies on the surface of the trunks, in the elimination of iron deficiency in the soil.

It is important to know that increased acidity is inherent in ferrous sulfate, in contact with green foliage, it leaves burns on it... For this reason, garden plantings are not treated with iron sulfate in summer and late spring. This should be done before the appearance or after the leaves fall. In most cases, it is during this period that fungal foci are formed. The fungus feeds on plant debris on the surface of trees and the surrounding soil. In such cases, it is necessary to treat with a disinfectant mixture not only green spaces, but also the adjacent soil.

Ferrous sulfate is also used to whitewash tree trunks. It is an effective disinfectant and is recommended for prophylactic purposes. To prepare whitewash, 100 g of powder is diluted in 1 liter of liquid. The drug should be sprayed in protective equipment, gloves and a respirator should be used. Otherwise, there is a risk of skin irritation, mucosal damage. Having sprayed apple trees with 1% composition of ferrous sulfate, the soil around the trees should be watered with the same solution.

Iron sulfate, used as a disinfectant, has both pros and cons.

The positive aspects of using this drug include:

• a wide range of actions;
• democratic price;
• effectiveness in the fight against fungal diseases;
• low toxicity.

The disadvantages of iron sulfate include:

• insufficiently high efficiency in the fight against harmful insects (to get rid of them completely, additional funds will be required);
• the ability to use only before and after the foliage is shed (the drug damages young shoots and leaves);
• rapid washing off with rain (the product starts working 2 hours after application, but it takes a day to achieve the maximum effect), if it is wet outside, the trees will have to be sprayed many times.

To eliminate bacterial diseases of trees, it is better to use other drugs. If the concentration is insufficient, ferrous sulfate will not help cure the fungus either. Another disadvantage of iron sulfate is associated with its rapid oxidation. Converting to ferric iron, it loses its fungicidal qualities. The protective effect lasts for about 2 weeks. Treatment of apple trees with iron sulfate in the spring slows down the swelling of the buds and the awakening of plants. Depending on the weather conditions, this can be regarded as both an advantage and a disadvantage. The delay is from 1 week to 10 days.

The main thing in preparing a solution for processing fruit trees is proportions. It is necessary to properly prepare the mixture in order to achieve maximum results from its application. To spray apple trees, dissolve 300 g of iron powder in 10 liters of liquid. This is how a 4% solution is obtained, it can be used not only for processing apple orchards, but also other pome trees.

The mixture can have a higher concentration - 5-6%. In this case, 500-600 g of the drug is taken for 10 liters of water. To combat harmful insects, a 5% solution is prepared. The treatment is recommended to be carried out in the fall after the leaves have flown. This will destroy the insects hibernating in the bark. For prophylaxis, a 1% mixture is used. This solution can be used to treat damaged areas.

With iron sulfate, apple trees are fed with a lack of this trace element in the soil both in the spring and in the autumn season. The lack of iron is indicated by the chlorosis of young foliage while maintaining its old color. To feed green spaces in 10 liters of water, it is necessary to dilute 50 g of powder. This mixture is applied to the trunk and soil every 4 days until green leaves appear.

To process apple trees with iron sulfate, you need to choose the right time. It could be autumn or spring processing. If the procedure is carried out in the spring, do it before the buds open. In autumn - after the leaf fall ends.

Preventive spraying in spring includes spraying the drug over the crown of apple trees. Unblown buds are also sprayed. It is optimal that the air temperature during the day was at least +3 degrees. 250 g of quicklime is dissolved in 10 liters of liquid (the water must be cold) and the same amount of ferrous sulfate in 2.5 liters of warm water. The lime substance must be filtered and mixed with a solution of ferrous sulfate. Plants are thoroughly sprayed with this mixture.

Autumn spraying is a preventive procedure. The amount of harvest next year depends on the correctness of the processing. Spraying a chemical in the fall does not replace or replace gardening in the spring. If you use iron sulfate incorrectly, it will have a bad effect on the state of green spaces. On the eve of processing, you should carefully read the instructions for the drug, to avoid mistakes when applying it.
