Copper is a micronutrient necessary for plants. The basic biochemical function of copper is participation in ferment reactions as an activator or forming part of copper containing enzymes. The quantity of copper in plants varies from 0.0001 up to 0.05% (in dry content) and depends on the kind of plant and the content of copper in soil. In plants copper is a part of some enzymes-oxidase and fibre cyanine.

In agriculture copper sulphate is used for various purposes. First of all, it is the oldest and the most effective fungicide — a means of protection of fruiters, bushes, grapevines and other plants from various fungal diseases.

Solutions of copper sulphate are used for spraying seeds before sowing for killing mycelial fungi on seeds.

Copper is the major micronutrient in plants. In life and development of plants copper as a micronutrient, is involved in synthesis of fibres, fats and vitamins, participates in photosynthesis and breath, raises immunity of plants to fungal diseases. Moreover, it raises frost resistance of many agricultural crops.

Copper deficiency is observed with excess of phosphorus, i.e. with excessive application of phosphoric fertilizers. As copper deficiency appears on rich manured soils or with excessive application of manure, there is a linkage of ions of copper with manure substances.

With copper deficiency the plant worsens or in general becomes fruitless, loses leaves, they curl, and the plant withers.

Copper deficient cereals become infected with so-called processing disease, fruit — exanthema. Copper micro fertilizers are applied as a preventive treatment against these diseases.

Recommendations on application

Copper sulphate is applied by spraying fruit trees and bushes against various diseases before buds open, and also for disinfection of wounds of fruiters:
  • apple-tree, pear, quince, grapevines — 100 gr. of copper sulphate per 10 litres of water;
  • apricot, peach, plum, cherry, sweet cherry, currant — 50-200 gr. per 10 litres of water;
  • Fruits (disinfection of wounds) — 100 gr. per 10 litres of water;
  • Treatment of walls and ceilings as a mordant before whitewashing — 600 gr. per 10 litres of water.
Before application of the solution it is necessary to mix and filter it. Spraying should be carried out in dry windless weather, in the morning or evening. Copper sulphate can be used as the means of scaring off hares. Take 30 gr. Naphthalene, 350 gr. laundry soap, 40 gr. Turpentine, 200 gr. vegetable oil, 10 gr. of copper sulphate and 1 litre of water.

Atáthe European exhibition ináMadrid copper sulphate ofáour enterprise has been awarded with aáprize for the best quality ináEurope.
Chemical products on the basis of copper sulphate are used for prevention of algae growth in swimming pools. These products do not influence the development of microorganisms, such as bacteria and viruses in water of swimming pools. To protect users of pools, chemical products on the basis of copper sulphate should be used with disinfectants.
