Preparation and use of the Bordeaux mixture

Today, the use of fungicides in agriculture has become a necessity. Because of the large number of fungal diseases, farmers have to fight for the crop with pests, as well as plant diseases. The most accessible and effective drug is the Bordeaux mixture.

For the preparation of this drug is used ordinary building lime and copper sulfate. The product is delivered to the market in cardboard boxes, and each package contains 5 paper indicators necessary for the preparation of the solution. The form of the product is a package with a mass of 600 and 900 grams.

The use of the Bordeaux mixture is associated with the preparation of the eponymous fluid by dilution with water. The resulting solution is used for the treatment of fruit trees (against scab, spotting), grapes (fighting mildew).

Spraying of plants using the Bordeaux mixture begins to produce in the early spring, before the leaves bloom. To do this, use a 3% solution of the drug. Before using the prepared solution, it is filtered with a gauze cloth - to avoid clogging of the nebulizer.

It is also possible to use the product during the growing season. In this case, prepare a 1% solution of the drug. The finished substance must be treated with the plant no later than an hour later.

The drug Bordeaux mixture is sold in two bags: blue (copper sulfate) and white (lime). Both packages should be carefully opened and poured into different containers (not metal ones). Add a small amount of warm water to the copper sulfate. Then add more liquid, bringing the solution to 5 liters.

In another container, a lime solution is prepared in the same way using water at room temperature. Prepared copper sulphate slowly, with a thin stream, pour into the lime. Both solutions must be cold by the time of the joint.

In order to check whether the Bordeaux mixture is ready, the instruction suggests mixing the resulting solution with a metal object. In the event that copper deposits on the metal, it is necessary to increase the concentration of lime in the solution.

When growing a large number of vegetables can not do without such a tool as the Bordeaux mixture. For cucumbers, it is necessary to prepare a drug with a lower concentration of active ingredient (0.5-0.75%). Thanks to this, after processing the plants during the growing season, you can eat the fruits obtained.

Thus, the correct use of the Bordeaux mixture will help get rid of fungal diseases and save plants. It should be remembered about the mandatory compliance with the proportion, preparing the solution for processing. Otherwise, the use of a highly concentrated preparation will lead to damage to the root system of the plant and its death. To avoid this, do not forget to check the acidity of the solution obtained with the test indicators that are included. Neglect of these rules will deprive you of the long-awaited harvest.
