Pyroxasulfone is a herbicide active ingredient used for pre-emergence weed control in a range of agricultural crops. It is classified as a Group 15 herbicide and works by inhibiting the synthesis of very-long-chain fatty acids, which are essential for plant growth. The herbicide primarily targets germinating weed seedlings before or shortly after they emerge from the soil.
Pyroxasulfone is used in crops including wheat, maize, soybean and cotton, depending on local product registrations. It helps control annual grasses and certain broadleaf weeds, including species that have developed resistance to other herbicides. In India, pyroxasulfone-based products are used in wheat and soybean cultivation, with applications and approved uses varying by product label and regulatory requirements.
Coverage of pyroxasulfone includes product launches, regulatory approvals, research findings and developments in weed management. News also examines its use in crop protection, herbicide resistance management and the wider agricultural inputs industry.
