Myclobutanil is a triazole chemical used as a fungicide.[1] It is a steroid demethylation inhibitor, specifically inhibiting ergosterol biosynthesis.[citation needed] Ergosterol is a critical component of fungal cell membranes. When heated myclobutanil decomposes to produce corrosive and/or toxic fumes, including carbon monoxide, carbon dioxide, hydrogen chloride, hydrogen cyanide, and nitrogen oxides.[2][3] Myclobutanil is banned in Canada, Colorado, Washington, and Oregon for the production of marijuana.[4]
