Copper sulfate (copper sulfate or copper sulfate) is an inorganic non-volatile compound. The substance has long been very actively used in construction and horticulture to protect plants. Also, the drug finds therapeutic use.

Description and hazard class of copper sulfate

A water-soluble powdery crystalline substance of a characteristic blue-blue color. The active component is represented by copper sulfate, the amount of which is 0.98 kg. A solution of the drug is used to protect and treat fungal lesions on fruit stands. Processing of vegetable and flowering crops, including roses, is also performed. The protective effect lasts for a month.

The mechanism of action is the reaction of copper ions and lipoprotein or enzyme complexes of a fungal or bacterial damaging factor. The result of the action is the appearance of irreversible changes in the protoplasm and nonspecific denaturation of protein compounds. Hazard class - 3Therefore, the drug is moderately dangerous. Proper preparation is carried out in accordance with the instructions supplied by the manufacturer of the drug.

Instructions for use of copper sulfate

A popular fungicidal agent is highly soluble in water and is widely used in the processing of any garden and garden plants, as well as in indoor floriculture. Spraying helps to cope with the lesions presented:

  • alternariosis;
  • ascochitosis;
  • moniliosis;
  • scab;
  • grape mildew;
  • spotting;
  • Septoria
  • downy mildew;

  • late blight.

Properties of copper sulfate

Copper sulfate-based solutions at the same time serve as a good foliar top dressing for many garden crops. ABOUTcopper deficiency in acidic sand and peat soils is especially noticeable. It can be used for disinfecting soil in protected and open ground. It is not recommended to use copper sulfate in the fall, due to the high risk of soil over-saturation with copper ions.

Features of the preparation of the solution

In the process of intensive stirring, the volume of water is added to 10 liters. The instruction does not involve the use of metal utensils.. To make a high-quality and most effective solution at the final stage, filtering is carried out.

Technology and terms of processing garden and garden plants

Dates and processing rules vary depending on varietal and botanical features of a garden or garden plant:

  • protection and treatment of apple, pear and quince in case of scab, phylosticosis and other common spotting, as well as moniliosis and drying, is carried out in a bucket of warm water 100 g of the drug. The first treatment in the early spring with a flow of 2-5 liters per fruit tree. You can re-hold the event a couple of weeks before the harvest;

  • protection and treatment of apricot, peach, plum, cherry and cherry in case of damage by clasterosporosis, coccomycosis and other common spots, moniliosis and curly leaves, carried out in a bucket of warm water 50-75 g of powder. The first treatment in the early spring with a flow rate of 2-3 liters per plant;
  • protection and treatment of gooseberries and currants in case of defeat by anthracnosis, septoria and other spotting is carried out in a bucket of warm water 50-75 g of powder. The first treatment in the early spring with a flow rate of one and a half liters per bush;
  • spraying seed potato tubers to protect against late blight before planting with a solution based on 2.0 g of the drug and 10 l of water.

Indoor flowering and ornamental foliage plants in complex prevention are treated with a solution consisting of a teaspoon of copper sulfate and a couple of liters of room temperature water. Watering under the root or spraying the aerial parts of the culture is carried out. Vegetables are sprayed with a 0.5% solution based on copper sulfate and urea.

How is spraying with copper sulfate roses

The use of copper sulfate is carried out with great care, so as not to harm the rose bushes. Spraying is carried out before the phase of active flowering of rose bushes, only at the vegetation stage. To process the aerial part against the defeat of black spotting and powdery mildew you need a 0.5% solution.

The use of copper sulfate, regardless of the season, is performed in the morning or in the evening, at air temperature in the range of 5-30aboutC, only in dry and calm weather. Before disinfecting garden or room rose seedlings, it is imperative to remove all bacterial cancerous growths on the root system, after which the roots are immersed in a solution based on copper sulfate for three minutes and then thoroughly washed in clean water. For foliar feeding of vegetative ornamental plants, the standard dosage is 1.5-2.0 g of copper sulphate per 10 liters of warm water.

What is the danger of copper sulfate for plants

Recently, Burgundy liquid based on copper sulfate and soda ash diluted in water has been especially popular. This version of the solution has similar Bordeaux mixture properties and qualitative characteristics. But, burgundy liquid has a stronger effect not only on pathogens, but also living plant tissuesTherefore, it can provoke burns on young foliage. To avoid burns, it is necessary to use a weaker 1% solution for spraying garden plants and garden crops.

Proper preparation of the liquid minimizes the risk of harm to garden plants, and also allows you to cover them with a special protective film. A mixture is applied similarly to Bordeaux fluid. Among other things, seed dressing allowedI and disinfection of the root system of seedlings before planting them in a permanent place.
