Appointment of fungicides and their varieties
Fungicides are used to eliminate the source of fungal infection and further protect the cultivated plant. By the nature of the effect, two types of fungicides are distinguished: protective and therapeutic. They should be used when characteristic symptoms are detected, as well as for preventive purposes.
Principle of action and function
The active components of fungicides penetrate into plant cells and identify pathogenic microorganisms. Further, they prevent further cell division, inhibit metabolic processes and subsequently contribute to the elimination of split pathogen residues. Many drugs also form immunity in the culture against this kind of infections..
The best drugs
Among the wide range of existing products, several of the most effective fungicides for cucumbers can be distinguished.
