説明
Triadimenol is a metabolite of triadimefon , a broad-spectrum chiral triazole fungicide, that is formed by reduction of a carbonyl group to the corresponding alcohol. It is teratogenic, inducing cranial nerve and ganglia abnormalities in a rat post-implantation whole embryo culture model when used at concentrations ranging from 12.5 to 125 μM. In vivo, triadimenol induces embryotoxicity in rats and rabbits when administered orally at doses of 100 and 40 mg/kg, respectively. Embryonic exposure to triadimenol (3-3,000 μg/L) induces embryonic mortality as well as decreases fertility and increases the number of female offspring in medaka fish (O. latipes).

使用
Triadimenol is used for the control of powdery mildews, rusts
and Rhynchosporium in cereals, and also as a seed treatment to control
bunt, smut and other cereal diseases. It is also used on vines, hops, coffee,
tomatoes, vegetables, fruit, tobacco, sugar cane, ornamentals and other
crops, mainly against powdery mildews, rusts and various leaf spot
diseases.

定義
ChEBI: A member of the class of triazoles that is 3,3-dimethyl-1-(1,2,4-triazol-1-yl)butane-1,2-diol substituted at position O1 by a 4-chlorophenyl group. A fungicide for cereals, beet and brassicas used to control a range of diseases including powdery mildew, ru
ts, bunts and smuts.

农业用途
Fungicide: Triadimenol is used to control seed-and soil-borne
diseases and to provide early season control of foliar
diseases. It is applied to seeds of barley, corn, oats, rye,
sorghum and wheat and also to fruits, vegetables and ornamentals. Registered for use in EU countries

代謝経路
When triadimenol is irradiated by UV light in methanol
solution, two major degradation products are identified
as 1-(4-chlorophenoxy)-3,3-dimethylbutan-2-one and
1-phenoxy-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-
2-ol. When a spray deposit on apple leaves is
exposed outdoors to natural sunlight, the only product
detected is the butanone metabolite. The butanone
metabolite has very low fungicidal activity against
apple powdery mildew, whereas the butanol metabolite
gives some control of infection.
