Systemic fungicide with preventive and curative action

Active ingredient: difenoconazole 250 g/l

Formulation: Emulsifable Concentrate (EC)

Mode of action:

Difenoconazole is a broad-spectrum fungicide that controls a wide variety of fungi – including members of the Ascomycetes, Basidiomycetes and Deuteromycetes families. It acts as a seed treatment, foliar spray and systemic fungicide. It is taken up through the surface of the infected plant and is translocated to all parts of the plant. It has a curative effect and a preventative effect. The mode of action of difenoconazole is that it is a sterol demethylation inhibitor which prevents the development of the fungus by inhibiting cell membrane ergosterol biosynthesis. It moves translaminarly, which allows it to be evenly distributed within the plant shortly after treatment. It is applied preventively and in early post-infection treatments, after the germination of the fungus on the plant surface, when it stops the infection. Difenoconazole has the longest period of curative application (up to 72 h after infection) of all triazoles.
