Myclobutanil is a triazole chemical used as a fungicide. It is a steroid demethylation inhibitor, specifically inhibiting ergosterol biosynthesis. 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. Myclobutanil is banned in Canada, Colorado, Washington, and Oregon for the production of medical and recreational marijuana; however, despite the Canadian ban, myclobutanil has been discovered in medical marijuana produced by at least one government licensed grower. In Michigan, the current state action limit for myclobutanil is 200 ppb in cannabis products.
