Verwenden
Fenarimol is a broad spectrum pyrimidine carbinol fungicide with
protective, curative and eradicative activities against powdery mildew
(Erysiphe spp., Pudusphaera leucutricha, Uncinula necatur, Sphaerutheca spp.,
Leveillula spp.) and scab (Venturia spp.) in many crops. It also controls
powdery mildew (Sphaerutheca pannusa) in ornamentals and Fusarium
patch (Micruduccium niuale), Take-all patch (Laefisaria fuciformis), Dollar
spot (Sderutina humeucavpa) and red thread (Gaeumannumyces graminis) in
turf and amenity grasses.
Allgemeine Beschreibung
Pure white crystalline solid. Used as a fungicide. Irritates skin and mucous membranes.
Reaktivität anzeigen
Fenarimol produces toxic gases when heated to decomposition.
Sicherheitsprofil
Moderately toxic by
ingestion. Experimental reproductive
effects. Mutation data reported. When
heated to decomposition it emits toxic
fumes of Cland NOx.
Stoffwechselwegen
The primary dissipation mechanism of fenarimol in the environment
involves photolysis on plants/soil surfaces and water. More than 80
photoproducts have been observed, resulting from the reduction of the
pyrimidine ring, hydrolysis, ring migration and cleavage of the phenyl
and pyrimidine ring moieties. Under laboratory conditions in the dark,
fenarimol is relatively persistent in soil, but a more rapid dissipation was
observed under field conditions with DT
50 values of 18-140 days, attributed
to photolysis of fenarimol on the soil surface. Fenarimol degrades
in/on plant foliage/fruit surfaces mainly by photochemical processes.
In animals, fenarimol is metabolised extensively to yield hydroxylated,
cleavage and dechlorination products. The primary photolytic and
metabolic pathways of fenarimol are presented in Schemes 1 and 2.
