On the green leaves, copper sulphate and preparations based on it are used accurately for treatment and prophylaxis until the spores from affected cultures are scattered to healthy plants.

Methods of using copper sulfate in horticulture

The most widely used means are as follows:

  • affordable, effective antiseptic;
  • fungicide for the pre-planting preparation of tubers, seeds, treatment of trees and shrubs;
  • a preparation for improving the quality of soil with a low concentration of humus and copper deficiency.

On soils with high sand content, on peat bogs and other areas where plants suffer from copper deficiency, the powdered preparation can be applied in the early spring and winter.

Copper vitriol is consumed at the rate of 1 gram per square meter, previously mixed with a small amount of substrate. On cultivated soils, the means, in order to avoid the accumulation of copper, are introduced at intervals of 4-5 years, in parallel, carrying out a crop rotation.

The use of copper sulfate in horticulture in spring is not limited to powder. The soil is decontaminated with a solution in a concentration of 5 grams of the substance per 10 liters of water. This measure helps to save annual crops from fusariosis, various kinds of rot, black leg.

At the height of vegetation, that is, in the middle of summer, if the plants show signs of chlorosis and oppression of growth, the ground beneath them is watered by a weak one, about 1 gram of copper sulfate per 10 liters of water, solution.
