FIERRO® 50 SC is a fungicide based on two active ingredients, one is Pyrimethanil, belonging to the chemical group of anilinopyrimidines that has good translaminar activity. It works by preventing the extension of the germ tube, thus stopping its penetration into the epidermal cells of the host. Added to this is a triazole (difenoconazole), which is an inhibitor of the synthesis of ergosterol, a component of fungal cell membranes, which inhibits the development of the germ tube and mycelial growth.
