Bordeaux liquid was invented at the end of the 19th century and is very popular in the fight against various kinds of pests and diseases in all areas of gardening for more than a century.

The use of Bordeaux liquid in horticulture helps in the treatment of perforation, molinosis and other diseases in stone fruit crops. It is an excellent prophylactic agent.

Bordeaux liquid of apple, quince, pear will relieve rot, scab, cancer and similar infections. For cherries, plums and apricots, this very remedy will also be salvation. It should be noted that these tree species are very sensitive, and an overdose of a product that contains copper will lead to the decay of the fruit.

How to use Bordeaux liquid?

Instructions for the use of boudros liquid in the garden are accessible and understandable even for a novice gardener.

It consists of two components:

• copper sulfate (scientifically called copper sulfate);
• quicklime.

It will not be difficult to cook it yourself. In addition to the named substances, it is necessary to have two buckets with a volume of 5 and 10 liters. The best options are plastic dishes, enameled or glass. This will eliminate a possible chemical reaction. It is not recommended to take an iron, zinc or aluminum bucket - in combination with copper, an undesirable reverse process will occur.

First, we prepare a lime solution in a ten-liter container:

1. Powder (the amount of grams depends on the concentration), pour hot water to extinguish lime (there should be a mushy mass);
2. After receiving the mixture, add here cold water(5 liters).

In the second container, we dilute the copper sulfate:

1. One hundred grams of powder is poured with the same amount of water as lime;
2. It is mixed and poured into the liquid of lime in a thin stream.

You need to pour vitriol into lime, but not vice versa. The concentration of the resulting mixture should be blue. It is checked for the amount of copper using litmus or any iron object.

There should be no red plaque on them, if there is one, then a little lime should be added. Red bloom means high copper content, and this contributes to the "burning" of the leaves.

The mixture is stored for no more than a day, the sooner the trees are sprayed with it, the better the result will be. If it is necessary to preserve the substance for two or three days, add 10 g of sugar and mix everything.

The concentration of the solution depending on the purpose of processing

The percentage of the solution depends on the purpose of its processing:

• A 1% solution is applied during the growing season. The number of sprays is not more than four. For its preparation, 150 g of lime and 100 g of copper are taken per 10 liters.
• 3% solution helps before kidney appears. It is used once a season. For the same amount of water as for a one percent solution, 400 g of lime and 300 g of vitriol are taken.

The classic combination in the solution is the ratio of 1% copper (vitriol) and the same lime.

To obtain a high-quality liquid, the components for its preparation are taken fresh. Drugs that have been in use for several years may not give the desired effect.

Consumption for the use of ready-made Bordeaux liquid in horticulture is calculated depending on the footage of the site. Trees and large shrubs require 15 liters per 100 sq. m, small bushes for the same volume of land take three times less solution.

The use of a stronger concentration is allowed only before bud break. After that, the strongest dosage should not exceed 3%.

Bordeaux liquid is not able to penetrate into trees, therefore it is intended only for the treatment of fungal infections.

On the different varieties trees as a separate dosage of the solution. For example, apple and pear trees are sprayed with 1% Bordeaux liquid six times during the growing season. Fruit can be eaten two weeks after processing.

In early spring, treatment of plants with Bordeaux liquid will relieve pome crops from scab, peaches from curliness, stone fruit trees will cure coccomycosis and moniliosis.

• do not mix the substance with soap;
