Used primarily as a selective herbicide to control broadleaf weeds and some grasses in crops like sugar beets, Chloridazon works by inhibiting photosynthesis in susceptible plants. It is applied pre- and post-emergence, providing effective weed management during critical growth stages. Due to its mobility in soil, it can leach into groundwater, raising environmental concerns, which has led to restrictions or bans in certain regions. Despite this, it remains useful in integrated weed control programs where resistance management and crop rotation are practiced.
