3% Bordeaux mixture has proven itself to be an inexpensive and effective remedy against fungal infections.
An expert of the online publication Belnovosti, agronomist, landscape designer Anastasia Kovrizhnykh told how to prepare the preparation at home.
To begin with, you will need to stock up on two 5-liter buckets made of plastic (iron containers are prohibited).
Pour 2 liters of hot water into one of them and dissolve 300 g of copper sulfate in it. Fill the other with 3 liters of cold water and add 400 g of lime.
Now add cold water to each of the buckets so that the volume of both solutions reaches 5 liters.
The lime suspension must be thoroughly mixed and then filtered through a cloth.
The only thing left to do is combine the solutions. To do this, while stirring the lime milk, pour the copper sulfate solution into it in a thin stream.
Use the resulting preparation to spray the garden. Trees should be treated before the buds open.
