Tebuthiuron 80% WDG

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

Tebuthiuron 80% WDG bir 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 .
