Description and Uses
Myclobutanil is a broad-spectrum systemic foliar-applied
fungicide of the substituted triazole chemical class of
compounds, with protective, eradicative, and curative action. It
disrupts membrane function in fungi by inhibition of sterol
biosynthesis.
It is produced by the alkylation of 4-chlorophenylacetonitrile
with butyl chloride, followed by treatment with dibromomethane
and sodium hydroxide in dimethyl sulfoxide. The
resulting intermediate is then reacted with the potassium salt of
1,2,4-triazole in dimethyl formamide.
Commercially, myclobutanil is presented as different
formulations or preparations with concentrations up to 60%
active ingredient (a.i.). It is formulated as a wettable powder
(2–40% a.i.) or as an emulsifiable concentrate (1–25% a.i.),
granular (<1% a.i.), dust (5% a.i.), dry flowable (60% a.i.), and
ready to use (<1% a.i.) solutions to be used in agriculture or in
domestic activities by homeowners.
It is also used at lower concentrations in combination
with other agrochemicals such as pyretroids (permethrin),
fludioxonil, mefenoxam, azoxistrobin, mancozeb, sulfur, or
fluoxastrobin.
Myclobutanil is an fungicide used on a wide range of food crops. Myclobutanil inhibits the biosynthesis of ergosterol, a critical componet of fungal cell membranes.
