The imidazole and triazole fungicides inhibit cytochrome P450 14 alpha-lanosterol demethylase (P45014DM) implicated in the ergosterol biosynthesis pathway, which is specific to fungi and yeasts.

Antifungal activity is based on inhibition of fungal CYP51 (lanosterol 14alpha-demethylase), and estrogen biosynthesis reduction is due to azole inhibition of CYP19 (aromatase).
Most potent fungicides included prochloraz, flusilazole, and imazalil, and most potent medicinal antifungals were bifonazole, miconazole, and clotrimazole.

Plant J. 1995 May;7(5):761-70.

However, these transgenic calli were killed by mixtures of gamma-kt plus fungicide inhibitors of LAN14DM such as ketoconazole, itraconazole or flusilazole which alone were not effective.
