Bordeaux mixture - instructions for use and preparation
For treatment of cultures use a solution of "strength" 1 or 3%. It is prepared immediately before spraying, mixing the components in strict sequence:
- For a 1% solution, 150 g of lime in 5 liters of water are quenched.
- 5 liters of hot water are poured into a separate dish and 100 g of copper sulfate are dissolved in it. Allow it to cool to room temperature.
- Mix both solutions, slowly pouring vitriol into the milk of lime.
You can extinguish lime in an iron bowl. But vitriol needs to be dissolved only in glass or plastic containers. Otherwise, it will react and lose its properties.
The technology for preparing a 3% solution is the same, only more components are taken: for 400 g of lime, 300 g of copper sulfate. The amount of water remains the same, 5 liters each, which are finally mixed into a common solution.
With a stronger solution of Bordeaux mixture (3%), cultures are treated to treat already manifested diseases. In this case, you can spray them only in early spring, before bud break. Or in the fall, when the leaves fall. During the growing season, only a 1% solution is used for processing the green mass for treatment or prevention.
What is Bordeaux liquid
In stores, you can still find a liquid preparation in bottles called "Bordeaux liquid". This is a ready-made concentrate of both components, lime and copper sulfate - that is, the same Bordeaux mixture.
The drug just needs to be diluted with water:
- to obtain a 1% solution - 100 ml per 10 liters of water;
- preparation of a 3% solution - 250 ml per bucket of water.
