Tebuconazole is a highly efficient, broad-spectrum, systemic triazole fungicide widely used in agricultural disease control. Below is its detailed product information:

1. Basic Information

  • Chinese Name: 戊唑醇
  • English Name: Tebuconazole
  • CAS No.:80443-41-0
  • Molecular Formula:C₁₆H₂₂ClN₃O
  • Molecular Weight:307.82

2. Physicochemical Properties

  • Appearance:Colorless crystal
  • Melting Point:102.4℃
  • Density:1.14g/cm³
  • Solubility
    • 32mg/L in water at 20℃
    • 200g/L in dichloromethane

    • <0.1g/L in hexane

3. Mode of Action

Tebuconazole inhibits the biosynthesis of ergosterol in pathogenic fungi, preventing cell membrane formation. This mechanism enables it to provide protective, curative, and eradicative effects against various diseases.

4. Applications

It controls numerous diseases across diverse crops:

 

  • Cereals: Rust, powdery mildew, net blotch, root rot, scab, smut, etc.
  • Fruit Trees: Banana leaf spot, citrus scab, apple powdery mildew, pear scab, grape powdery mildew, etc.
  • Other Crops: Sclerotinia stem rot in rapeseed, etc.

5. Formulations

    • Moderate toxicity to fish (96h LC₅₀: 8.7mg/L for goldfish, 6.4mg/L for rainbow trout)
    • Safe for bees when used as directed.

7. Precautions for Use

  • Seed Dressing:Do not exceed 6g of tebuconazole per 100kg of wheat or corn seeds to avoid reducing germination rate and speed.
  • Feed Prohibition:Treated seeds must not be used as feed.
  • Sowing Timing:Avoid use in fields sown too late, as low temperatures after sowing may impair seed emergence.
