Tebuthiuron 80% WDG

Tebuthiuron 80% WDG – Soil-Residual Herbicide for Total Vegetation Control

Tebuthiuron 80% WDG a persistent urea herbicide formulated as a water-dispersible granule, designed for long-term suppression of broadleaf weeds, grasses, and woody plants in non-crop areas (industrial sites, railways) and select crops (sugarcane, pineapples). As a photosynthesis inhibitor (PSII, HRAC Group 5), it provides 1–2 years of residual control through root uptake and soil mobility, making it ideal for low-maintenance vegetation management .

Afzalliklar va cheklovlar

Afzalliklar:
✅ Long-Term Control: 12–24 months suppression after single application.
✅ Tejamkor: Reduces mechanical clearing by 80% in trials.
✅ Qarshilikni boshqarish: Glifosatga chidamli begona o'tlarga qarshi samarali.

Cheklovlar:
⚠️ Non-Target Damage: Root zone migration kills adjacent vegetation.
⚠️ Qat'iylik: Residual activity limits land reuse (wait 24+ months for sensitive crops).

A: Activated charcoal (1–2% w/w) or microbial remediation (Pseudomonas spp.) over 6–12 months .

Q: Alternatives for eco-sensitive areas?
Javob: ga o'tish indaziflam (lower persistence) or mechanical/thermal weeding.

⚠️ Compliance Notice:
Bu mahsulot highly regulated due to environmental persistence. Always:

  1. Conduct soil percolation tests before application.

  2. Consult local groundwater vulnerability maps.

  3. Saqlash detailed application records for auditing.
