Tebuconazole (25 EC) is an emulsifiable concentrate formulation of the systemic triazole fungicide Tebuconazole, containing 250 grams of active ingredient per liter. It is widely used in agriculture to control a broad spectrum of fungal diseases in many crops, including cereals, fruits, vegetables, oilseeds, and ornamentals.
Tebuconazole acts as a demethylation inhibitor (DMI) fungicide, disrupting sterol biosynthesis in fungal cell membranes.
