Features of Tebuconazole
1. Broad Spectrum of Activity: Tebuconazole can be widely used to control various diseases, including damping-off, anthracnose, leaf spot, root rot, black star disease, brown spot disease, sclerotinia, fusarium, black smut, silver smut, powdery mildew, stripe rust, leaf rust, large spot, small spot, gray mold, and many others.
2. Good Systemic Activity: Tebuconazole has excellent systemic properties. After application, it absorbs through the roots, stems, and leaves, and it can be transmitted to any part of the plant.
3. Long Residual Activity: Due to its good systemic properties, tebuconazole can be used for both spraying and seed treatment. Once absorbed by the crops, it remains in the plant for an extended period to continuously kill pathogens. The residual activity lasts 15 to 20 days for foliar applications, over 80 days for seed treatment, and can exceed 100 days when soil-applied.
4. Regulation of Crop Growth: As a triazole fungicide, tebuconazole suppresses the division and elongation of plant cells. When used at the recommended dose, it can control vegetative growth, promote reproductive growth, and enhance the transport of nutrients into the fruit. This leads to increased content of sugars, proteins, and other solid materials in the fruit, improved seed fullness, higher thousand-grain weight, and better fruit quality.
5. Protective, Therapeutic, and Eradicative Actions: Tebuconazole works by inhibiting ergosterol in the cell membranes of pathogens, which suppresses mycelial growth and spore formation, effectively killing the pathogens. It offers comprehensive prevention, treatment, and eradication of diseases.
6. Good Compatibility: Tebuconazole can mix with various agents, including prochloraz, propineb, thiram, difenoconazole, and azoxystrobin. This compatibility results in notable synergistic effects, expanding the spectrum of activity, preventing the development of resistance, and enhancing the efficacy against diseases.
7. Diverse Application Methods: Tebuconazole can be applied through foliar spraying, seed treatment, soil application, and root drenching for therapeutic purposes.

Application
For wheat, when using tebuconazole, it is recommended to apply the 43% tebuconazole suspension for disease prevention at a minimum dilution of 1,000 times (15 ml per 1 bucket of water). For treating diseases such as leaf blight and rust, a dilution of at least 500 times (30 ml per bucket of water) is necessary to ensure effectiveness. (When mixing with other agents, consider reducing the dosage.)
For peanuts, during the seedling stage, it is recommended to spray the 43% tebuconazole suspension at a dilution of 1,000 to 1,500 times to prevent leaf spot disease. A higher dosage of tebuconazole during this stage may inhibit seedling growth. In the mid to late growth stages, it is advisable to use a dilution of 750 to 1,000 times for preventing leaf spot disease. For treating leaf spot disease in the mid to late stages, a dilution of 500 to 750 times (20-30 ml per bucket of water) is recommended.
For fruit trees, the dosage of tebuconazole should be lower than that for field crops. A lower dosage can effectively prevent leaf spot disease, rust, and powdery mildew. For preventive measures when no disease is present, apply the 43% tebuconazole suspension at a dilution of 4,000 to 5,000 times. For treating leaf spot disease and similar issues, it is advisable to use the 43% tebuconazole at a dilution of 2,500 to 3,000 times.
For seed treatment with tebuconazole, there has been a significant increase in usage in recent years. Since tebuconazole can inhibit root development, special care must be taken during use. It is generally recommended to use 10 ml of the 6% tebuconazole seed coating suspension per 25-30 kg of seeds, effectively preventing leaf spot disease in peanuts and damping-off in wheat.
