Tebuconazole is widely used as a fungicide in agriculture to protect crops from fungal infections. It is effective against a broad spectrum of fungal diseases, including powdery mildew, rusts, and leaf spot diseases, in crops such as cereals, fruits, vegetables, and ornamental plants. The chemical is applied as a foliar spray, seed treatment, or soil treatment, depending on the crop and the type of fungal infection. Its systemic action allows it to be absorbed by the plant and distributed throughout its tissues, providing long-lasting protection. Additionally, tebuconazole is used in wood preservation to prevent fungal decay in timber and other wood products. Its ability to inhibit ergosterol biosynthesis in fungi makes it a key component in maintaining crop yield and quality, as well as extending the lifespan of wood materials.
