Propiconazole

Propiconazole is a triazole fungicide, also known as a DMI, or demethylation inhibiting fungicide due to its binding with and inhibiting the 14-alpha demethylase enzyme from demethylating a precursor to ergosterol.

Without this demethylation step, the ergosterols are not incorporated into the growing fungal cell membranes, and cellular growth is stopped.

[citation needed] Propiconazole is used agriculturally as a systemic fungicide on turfgrasses grown for seed and aesthetic or athletic value, wheat, mushrooms, corn, wild rice, peanuts, almonds, sorghum, oats, pecans, apricots, peaches, nectarines, plums, prunes[2] and lemons.

[3] Propiconazole is a mixture[4] of four stereoisomers and was first developed in 1979 by Janssen Pharmaceutica.

[5] Propiconazole exhibits strong anti-feeding properties against the keratin-digesting Australian carpet beetle Anthrenocerus australis.
