CAS 447399-55-5: Pyroxasulfone

Description: Pyroxasulfone is a selective herbicide primarily used in agriculture for the control of annual grasses and certain broadleaf weeds. It belongs to the class of sulfonylureas and functions by inhibiting the enzyme acetolactate synthase (ALS), which is crucial for the synthesis of branched-chain amino acids in plants. This mechanism of action makes it effective in pre-emergence applications, preventing weed seed germination and growth. Pyroxasulfone is characterized by its relatively low toxicity to mammals and its environmental stability, which allows for effective weed management with minimal impact on non-target organisms. It is typically formulated as a granular or liquid product and is often used in combination with other herbicides to enhance its efficacy and broaden the spectrum of weed control. Additionally, its application is subject to specific guidelines to minimize potential environmental risks, particularly concerning water sources and non-target plant species. Overall, pyroxasulfone represents a valuable tool in integrated weed management strategies in various crop systems.
