Cultivation of land with copper sulphate before planting: application and how to breed

Copper sulfate is known to gardeners as a good antiseptic and antifungal agent. It is available and cheap, effective, despite the fact that this is far from a new drug. Consider the cultivation of the land with copper sulphate before planting, why it is carried out, how to prepare a solution. How to treat them with soil and plants in the garden, vegetables, as well as greenhouses. How to stay safe.

Why do we need to cultivate the land with copper sulfate

The substance is used to disinfect soil and tree bark from various infections and fungi. In addition, copper enters the soil - an element necessary for the development of plants. Especially useful is the introduction of copper in peatlands, where there is a shortage of copper.

Treatment in early spring or mid-autumn allows control of overwintering pests and overwintering pathogens. Cleansing the soil of spores and bacteria helps to reduce the number of root rot pathogens and other diseases that are carried in the ground.

Traditionally, a solution of vitriol is used to disinfect the internal structures of greenhouses from diseases accumulated over the season and pests hiding in them.

Preparation of working solution

There are 2 varieties of copper sulfate solution for processing: 3% and 1%. The first is used for processing trees and soil, the second - for processing green plants. To obtain a 3% concentration, it is necessary to dilute 300 g of powder in 10 liters; to obtain a liquid of 1% concentration, dilute 100 g per 10 liters. To spill the soil, prepare a solution of 5 g of powder per 10 liters of water.

Water for dissolving the powder is recommended to take warm, but not hotter than 50 °C. It is not necessary to dissolve the entire volume of the powder in water at once, you can dilute it first in a small amount, and then add water. To prepare and store the drug, you need to take non-metallic dishes, a plastic or enameled bucket will do.

How to cultivate the land with copper sulfate

In different cases, a fungicidal agent with an unequal concentration is used. The way they are used is also different.

For soil

A solution of a fungicidal agent is shed on the soil in the beds in the fall, after a complete harvest and plant residues. Application in the garden will be as follows: you need to dig up the beds, as usual, break up the clods and level, moisten the soil from the watering can, spending on each square. m. 10 l funds.

For the garden

3% solution is used for spraying tree trunks and branches. It is carried out in early spring, when the buds have not yet blossomed. Do not spray on green leaves, a burn is possible. If spraying is carried out later than necessary, it will no longer be useful, the pests will have time to get out from under the bark and spread over the plant. Reapply in autumn when the leaves fall from the trees, but before the cold sets in.

Vegetables

Disinfection of plants with a solution of vitriol is carried out at the initial signs of the disease. Use a weak 1% solution. Plants are wetted from a sprayer until their leaves are wet.

For greenhouse

Sprinkling of the greenhouse is done before the start of cultivation or at the end of the season, in the course of preparing the structure for winter. The greenhouse is cleared of vegetation residues, repaired, gaps are closed and damages are repaired. Wash glass, film or polycarbonate with water and dry.In places where mold is found, it is cleaned and smeared with a concentrated solution of vitriol. Wooden structures and wall surfaces are treated with a 3% solution.

How to stay safe

Copper sulfate, when it comes into contact with the skin in dry and liquid form, leads to irritation. To minimize contact with the drug, gloves should be worn on the hands when preparing the solution and when spraying. Wear tight clothing, goggles and a respirator. Carry out disinfection at a temperature of 5-20 °C. After finishing work, wash your hands with soap and water, rinse your mouth, rinse the solution from your skin.

Do not pour the remaining solution on the ground near water sources. It is forbidden to use a more concentrated liquid than necessary for use, otherwise you can burn the leaves and young stems - the plants will either slow down growth or die.

Copper sulfate is a reliable disinfectant for treating trees and shrubs from wintering pests. Destroys pathogens in the soil and on the surfaces of household structures: greenhouses, cellars, sheds. It is widely used both in private households and in the agricultural industry as one of the powerful, simple and effective fungicides.
