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."
