Another advantage of the product is its unlimited shelf life. The drug combines well with many pesticides. When used correctly, it demonstrates high efficiency.
To increase the adhesion of the solution to crop plants, it is worth adding a little skim milk with a concentration of 1% to the solution.

Are copper oxychloride and copper sulfate the same thing?
Vitriols are crystalline hydrates of sulfuric acid with divalent metals and have the formula CuSO4·5H2O. In this case, the formula of copper oxychloride is Cu3H8O7CuCl2. This means that the substances are completely different salts.
