NOMENCLATURE
Common name flutriafol (BSI, ANSI, draft E-ISO, (m) draft F-ISO)
IUPAC name (RS)-2,4'-difluoro-a-(1H-1,2,4-triazol-1-ylmethyl)benzhydryl alcohol
Chemical Abstracts name (?-a-(2-fluorophenyl)-a-(4-fluorophenyl)-1H-1,2,4-triazole-1-ethanol


Flutriafol APPLICATIONS
Biochemistry Inhibits ergosterol biosynthesis (steroid demethylation inhibitor), causing fungal cell wall collapse and inhibition of hyphal growth. Mode of action Contact and systemic fungicide with eradicant and protective action. Absorbed by the foliage, with translocation acropetally in the xylem. Uses Control of a broad spectrum of leaf and ear diseases (including Erysiphe graminis, Rhynchosporium secalis, and Septoria, Puccinia, and Helminthosporium spp.) in cereals, at 125 g a.i./ha. Also used in non-mercurial seed treatment formulations to control the major soil-borne and seed -borne diseases of cereals. Formulation types SC. Selected tradenames: 'Impact' (Cheminova); mixtures: 'Vincit' (+ imazalil+ thiabendazole) (Cheminova)

OTHER TRADENAMES
'Cicero' (Cheminova); 'Pointer' (Cheminova) mixtures: 'Early Impact' (+ carbendazim) (Cheminova); 'Ferrax' (+ ethirimol+ thiabendazole) (seed) (Syngenta, Cheminova); 'Halo' (+ chlorothalonil) (Syngenta, Cheminova); 'Impact Excel' (+ chlorothalonil) (Syngenta, Cheminova); 'Pacer' (+ carbendazim) (Cheminova); 'Palette' (+ carbendazim) (Cheminova); 'PP 375' (+ chlorothalonil) (Syngenta, Cheminova); 'Prospa' (+ chlorothalonil) (Syngenta, Cheminova)
