Pyroxasulfone is a pre-emergence herbicide widely used in modern agriculture to control a broad spectrum of grass and broadleaf weeds in crops such as maize, wheat, soybean, and cereals. It offers long-lasting soil residual activity and provides farmers with early-season weed control, ensuring optimal crop establishment and higher yield potential.
Pyroxasulfone inhibits very long chain fatty acid (VLCFA) biosynthesis, which is essential for cell division and growth in weeds.
By disrupting root and shoot development in emerging weeds, it prevents weed establishment at early stages.
Systemic in soil: absorbed by roots of germinating weeds, ensuring long-lasting residual control.
Most effective when applied pre-emergence or early post-emergence before weed growth becomes competitive.
✔ Broad-spectrum weed control – effective against annual grasses and key broadleaf weeds.
✔ Long residual activity – maintains weed suppression for several weeks, reducing the need for multiple applications.
✔ Crop safety – selective for most cereals and soybean when applied at recommended rates.
✔ Low application rate – economical and environmentally friendly.
✔ Flexible application methods – suitable for soil incorporation, pre-plant, or pre-emergence spray programs.
Apply only to prepared fields or clean soil surfaces before crop emergence.
Avoid application under drought, flooding, or extreme stress conditions.
Prevent drift or runoff into sensitive crops or water bodies.
Use personal protective equipment (PPE) during handling and application.
Always follow local crop label guidelines and regulatory instructions.
Q1: Which crops is Pyroxasulfone safe for?
A: Mainly maize, wheat, soybean, and most cereals when applied according to label instructions.
Q2: What weeds does Pyroxasulfone control?
A: Annual grasses such as foxtail, barnyardgrass, ryegrass, and some broadleaf weeds.
Q3: When should it be applied?
A: Pre-emergence or early post-emergence for optimal soil residual activity.
Q4: How quickly does it work?
A: Weed germination and early growth inhibition can be observed within 1–2 weeks.
Q5: Can it be tank-mixed with other herbicides?
A: Yes, compatible with certain broad-spectrum herbicides for extended weed control.
