3883 Difenoconazole Difenoconazole is a broad spectrum fungicide that controls a wide variety of fungi – including members of the Aschomycetes, Basidomycetes 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. Difenoconazole can be applied to winter wheat, oilseed rape, Brussels sprouts, cabbage, broccoli/calabrese and cauliflower. It controls various fungi including Septoria tritici, Brown Rust, Light Leaf Spot, Leaf Spot, Pod Spot, Ring Spot and Stem canker. It also prevents Ear Discolouration in winter wheat. 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. 119446-68-3 86173 C19H17Cl2N3O3 White powder.
