Beschreibung
Difenoconazole is a kind of triazole-type fungicide. It is a broad-spectrum triazole fungicide. It takes effect through acting as the inhibitor of sterol 14α-demethylase, blocking the biosynthesis of sterol. Through inhibiting the sterol biosynthesis process, it inhibits the mycelia growth and germination of pathogens by spores, ultimately suppressing the proliferation of fungi. Difenoconazole has been extensively used in a wide range of crops in many countries due to its ability to control various fungal diseases. It is also one of the most important and widely-used pesticides for disease control in rice.
Verwenden
Difenoconazole is a fungicide with broad-range activity, protecting
yield and quality by foliar application or seed treatment. It provides
long-lasting and curative activity against Ascomycetes, Basidiomycetes
and Deuteromycetes. It is used against disease complexes in grapes, pome
fruit, stone fruit, potatoes, sugar beet, oilseed rape, banana, ornamentals
and various vegetable crops. It is also used as a seed treatment against a
range of pathogens in wheat and barley.
Definition
ChEBI: A member of the class of dioxolanes that is 1,3-dioxolane substituted at position 2 by 2-chloro-4-(4-chlorophenoxy)phenyl and 1,2,4-triazol-1-ylmethyl groups. A broad spectrum fungicide with novel broad-range activity used as a spray or seed treatment. It
is moderately toxic to humans, mammals, birds and most aquatic organisms.
Landwirtschaftliche Anwendung
Fungicide: For suppression of fungi diseases in crops and seeds.

Stoffwechselwegen
There is limited published information on the metabolism of difenoconazole.
It is slowly dissipated in soils, and metabolism in plants involves
rupture of the triazole linkage or oxidation of the phenyl ring followed by
conjugation.
