Today, the use of fungicides in agriculture has become a necessity. Due to the large number of fungal diseases, farmers have to fight for crops with pests, as well as plant diseases. The most affordable and effective drug is Bordeaux mixture.
To prepare this drug, ordinary building lime and
copper sulfate are used. 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 release of the product is packaging weighing 600 and 900 grams.
The use of Bordeaux mixture is associated with the preparation of the same liquid by dilution with water. The resulting solution is used to treat fruit trees (against scab, spotting), grapes (fight against mildew).
Spraying plants using Bordeaux mixture begin to produce in 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 gauze to prevent clogging of the atomizer.
It is possible to use the product during the vegetation of plants. 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 Bordeaux mixture is sold in two sachets: blue
(copper sulfate) and white (lime). Both packages must be carefully opened and poured into different containers (not metal). Add a small amount of warm water to 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 room temperature water. Cooked sulphate slowly, with a thin stream, poured into lime. Both solutions should be cold at the time of connection.
In order to check if the Bordeaux mixture is ready, the instruction suggests mixing the resulting solution with a metal object. If copper deposits on the metal, it is necessary to increase the concentration of lime in the solution.
When growing a large number of vegetables, it is impossible to do without such a remedy as the Bordeaux mixture. For cucumbers, it is necessary to prepare a drug with a reduced concentration of the active substance (0.5-0.75%). Thanks to this, after processing the plants during the growing season, you can eat the resulting fruits.
Thus, the correct use of Bordeaux mixture will help get rid of fungal diseases and preserve plants. In this case, you must remember that the proportion must be respected, preparing a 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 resulting solution using the test indicators that are in the kit. Neglect of these rules will deprive you of the long-awaited harvest.
