| Questions And Answer | Back Directory | [Description]
Tebuconazole is a trazole fungicide. It is taken up by plants and transported within tissues. It is used as a seed dressing, which works effectively against various smut and bunt diseases of cereals. As foliar spray tebuconazole controls numerous phathogens such as rust species, powdery mildew, and scale in various crops. It is also used to control pests including yellow leaf spot, black spot, net blotch, and Scelerotinia rot.
Tebuconazole can be applied to control above mentioned diseases on cereals (including wheat, barley, oat, rye), grapes, peanuts, vegetables (onions and peas), bananas, sugarcane.

Tebuconazole used as a seed dressing is effective against various
smut and bunt diseases of cereals. Used as a spray it controls numerous
pathogens in various crops: rust species, powdery mildew, Rhyncosporum
secalis, Sqtoria spp., Pyrenophora spp., Fusarium spp. in cereals,
Mycosphaerella spp. in bananas, Pucciniu spp. and Sclerufium roIfsii in
peanuts. | [Definition]
ChEBI: 1-(4-chlorophenyl)-4,4-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl)pentan-3-ol is a tertiary alcohol that is pentan-3-ol substituted by a 4-chlorophenyl, methyl, methyl, and a 1H-1,2,4-triazol-1-ylmethyl at positions 1, 4, 4 and 3 respectively. It is a member of monochlorobenzenes, a member of triazoles and a tertiary alcohol. | [Agricultural Uses]
Fungicide, Plant growth regulator: Used as a seed treatment against smuts and bunts
of cereals; as a foliar spray against diseases of cereal, peanuts,
oilseed rape, grapes, bananas, stone fruit, and pome
fruit. Registered for use in EU countries. Registered for
use in the U.S. | [Trade name]

Tebuconazole is degraded in soils and does not accumulate. In plants the
metabolites were mainly compounds containing triazole, and in mammals
tebuconazole was rapidly metabolised and excreted in urine and
faeces. | [storage]
Store at -20°C | [Degradation]
Tebuconazole is stable to elevated temperatures. Under sterile conditions
it is stable to hydrolysis in water. It is hydrolysed slowly with a DTS0 of
>1 year.
Only two products were formed by irradiation of a suspension of tebuconazole
in water with UV light (>280 nm). These were the hydrochloride
(3) and 1,2,4-triazole (2). The expected product in which chlorine was replaced by hydroxyl could not be isolated. In organic solvents a number
of products were formed. Several products (3, 4, 5, 6, 7, 8, 9, 12, 13, 14)
were isolated from benzene after 72 hours irradiation (>280 nm). In a
number of cases products isolated from photolysis in benzene were
formed by reactions in which the solvent participated and involved
addition of a benzene molecule (4, 9, 5, 6). On irradiation in methylene
chloride and methanol, 4-chloracetophenone (10) and acetophenone (11)
were also identified in addition to starting material and 1,2,4-triazole
(Wamhoff et al., 1994). |
