Fungicide acts in two ways: First, the protective fungicide, the second is the suction fungicide. Protective fungicides in the plant in vitro or body surface directly contact with pathogens, kill or inhibit pathogens, so that they can not enter the plant, so as to protect the plant from pathogens hazards. Such fungicides known as protective fungicides, its role in two ways: First, after spraying agents and pathogens contact directly kill pathogens, that is, "contact sterilization"; the other is the agent sprayed on the surface of the plant , When the pathogen falls on the plant body exposed to the drug and was poisoned, known as the "residual effect of bactericidal effect."
