Myclobutanil is a conazole class fungicide widely used as an agrichemical. It is approved for use on fruit, vegetables and seed commodities in the EU and elsewhere to control fungi such as Ascomycetes, Fungi Imperfecti and, Basidiomycetes. Myclobutanil products are registered and authorized for use in all countries in which they are sold,
including, but not limited to: Australia, Canada, India, New Zealand, South Africa, the European
Union and the United States. Its mode of action is inhibition of the enzyme C14 demethylase which is involved
in the synthesis of ergosterol, a component of fungal cellular membranes.

The acute oral LD50 for mice is 1360 mg/kg, and ranges from 1.75 to 1.8 g/kg for rats.
Route of Administration:
Oral
HepG2 cell viability was assessed with the MTT assay after 24 h of exposure to myclobutanil at different
concentrations (range: 0.1–500 ppm). The fungicide reduced cell viability at all
concentrations tested. In particular, the cytotoxic effect was partial from 1 to 10 ppm, but from 100
to 500 ppm there was near total cell death. Indeed, myclobutanil reduced cell viability to <50% at
100 ppm and to <10% at 500 ppm.
