Appointment of fungicides and their varieties

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.

Impact principle 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..
