Instructions for use of copper sulphate from phytophthora


The plans of each gardener is measures to prevent plants from fungal diseases. One of the most affordable tools used for treatments is copper sulphate. The effectiveness of its use, instructions and rules for preparing a working solution from phytophthora will be discussed in this article.

In what cases resort to copper sulphate?

For many decades to a row, copper sulfate does not lose its relevance in gardening works. It is used as a crop protection against fungal infections:

  • scab;
  • white spot;
  • ascohitosis;
  • monilioz;
  • downy mildew;
  • phytophtora and other diseases.

In addition to prophylactic purposes, the tool is used for foliar dressings. Often, plants growing on acidified, sandy or peat soils are deficient in copper. 1-2 treatments are enough to compensate for the lack of trace elements in the soil.

Pre-sowing works usually begin with soil disinfection. Alternatively, in this case, use a solution of copper sulfate. Also, the tool acts as an antiseptic for wooden structures. Spraying the tree prevents the formation of mold or mildew. Gardeners often resort to such a method for arranging greenhouses or other garden structures.

It is better to use the fungicide in spring and summer. It is not recommended to use it before winter, in order not to overpower the soil with copper ions.

Advantages and disadvantages of using

The main advantage of copper sulfate is that the active substances of the agent remain after spraying on the surface of the plant, without being absorbed into the greens and fruits. Thanks to this, it is possible to get a crop that is safe for people's health. Among other benefits:

To prepare the working solution, it is necessary to dissolve the blue crystals in water. The product in an amount of 50 grams is diluted first in a small amount of liquid, then, after thorough mixing, the total volume is brought to 5 liters. Properties of active substances persist throughout the day. The dissolved vitriol is not subject to long-term storage, therefore it is recommended to prepare a new portion immediately before use.

When working with copper sulphate it is necessary to wear gloves and goggles to protect the skin and mucosa from direct contact with the solution. When carrying out processing it is impossible to use water and food, and also to smoke. In case of contact with the open areas of the skin or mucous membrane, it is recommended to immediately wash the affected area with plenty of water.

Insecticide belongs to the 3rd hazard class, which indicates a low level of toxicity when used in small quantities. Therefore, when preparing the working solution, one should adhere to the indicated dosage so that the fruits do not accumulate toxins in themselves.

An insecticide is a chemical, therefore when using it in the household, you should follow some rules:

Alexey Petrovich, 53 years old.I have been growing tomatoes for several years in a row without facing the problem of phytophtoras. I use copper sulphate at least 3 times per season. The first time I disinfect the seeds, the second time 1 l per well before planting the seedlings, the third time before flowering as a foliar application.

Anastasia, 36 years old. I water the soil with a solution of copper sulphate before each planting, but the tomatoes are still affected by blight. Means I cook correctly, I adhere to the rules of watering. Maybe something else missed or copper sulfate is not so effective?

Timur, 46 years old. Copper sulfate in the farm - the first assistant. In the greenhouse, all disinfection is performed with a blue liquid, the earth is also disinfected with it. Yes, and seeds stand before sowing in a weak solution. Tomatoes are obtained one-on-one, with no signs of late blight.

Vladlen Vitalyevich, 51 year. Copper sulfate has been used for gardening for more than 30 years. I have never purchased chemicals based on chemicals due to mistrust and unwillingness to poison the fruits. And I disinfect the soil for seedlings and beds before planting with copper solution, and work on the greenhouse in the spring. The best assistant is hard to find. With phytophthora tomatoes copes as wonderfully as with other tasks. Recommend!

Sophia, 49 years old. I was completely terrified when, after the rain, I discovered brown specks on ripening tomatoes. I didn’t want to remain without a crop, I asked for help from my country house neighbor. She advised to treat twice the bed with a solution of copper sulphate. The tool perfectly coped with the problem. In the household, as it turned out, the copper-containing drug is an indispensable thing.

When using several varieties of insecticides at once, it should be remembered that copper sulphate incompatible with alkaline decomposable preparations (for example, organophosphates).
