  • Applications

    Oxadiargyl (CAS 39807-15-3) is an herbicidal active ingredient used in agriculture to control weeds in registered crops. Typical applications include pre-emergence and early post-emergence weed control, formulated as emulsifiable concentrates (EC) or granules, and it may be tank-mixed with other herbicides to enhance efficacy. Use is governed by regional registrations and local regulations, with the aim of protecting crop yields and managing weed pressures across diverse cropping systems.
