Pyroxasulfone 98% TC | Long-Lasting Pre-Emergent Herbicide Technical Concentrate
Residual Weed Control for Soybean, Corn & Cereals | Low Application Rate Formula
Product Description
Pyroxasulfone 98% TC is a premium pre-emergent herbicide that provides long-lasting control of annual grasses and broadleaf weeds. It works as a VLCFA inhibitor, disrupting cell division in germinating weeds for high effectiveness across various cropping systems. With 98% purity, this formulation delivers reliable performance while supporting sustainable farming practices.
Key Features & Benefits
1. Long-Lasting Control
Delivers up to 12 weeks of residual activity, creating a soil barrier that prevents weed emergence during critical crop establishment.
2. Broad-Spectrum Effectiveness
Controls key annual weeds including Digitaria spp. (crabgrass), Echinochloa crus-galli (barnyardgrass), Amaranthus spp. (pigweed), and Chenopodium album (lambsquarters).
3. Crop Safety
Causes minimal plant damage in tolerant crops when applied at recommended rates, improving crop establishment and yield potential.
4. Effective Soil Distribution
Features optimal solubility (3.2 mg/L at 20°C) and moderate soil adsorption (Koc=300-500), ensuring even distribution throughout the root zone for consistent weed control.
Applications
Target Crops
Field Crops: Maize, Soybean, Wheat

Usage Instructions
Application Guidelines
Rate: 100–250 g/ha (adjust based on soil texture, organic matter content, and target weeds).
Timing: Apply pre-plant or pre-emergence; incorporate mechanically or via irrigation (≤5 cm depth).
Method: Ground sprayer with 200–400 L/ha spray volume.
Compatibility: Stable with most common herbicides (e.g., Atrazine, Metolachlor); conduct jar tests before mixing.
Critical Recommendations
Apply to moist soil for optimal activation.
Avoid use in coarse-textured soils with <1% organic matter.
Safety & Environmental Information
Handling & Storage
PPE Requirements: Nitrile gloves, goggles, respirator (NIOSH-approved).
Storage: Keep in original container at 10–25°C; protect from direct sunlight and moisture.
Shelf Life: 36 months when sealed; 6 months after opening.
Environmental Stewardship
Aquatic Safety: Highly toxic to aquatic invertebrates (LC50 <0.1 mg/L). Maintain 30-meter buffer zones from water bodies.
Pollinator Protection: Low bee toxicity (LD50 >100 μg/bee); apply when bees are not foraging.
Soil Health: Half-life = 30–90 days (aerobic); avoid consecutive applications to prevent buildup.
Regulatory Compliance
EPA Registration: Approved under FIFRA §3.
REACH: Fully registered (EC No. 700-958-8).
Disclaimer: Always read and follow local label instructions. Not registered in all jurisdictions; confirm local regulatory status before use.
