Sodium 2,2-Dichloropropionate, commonly known as dalapon sodium, is a selective herbicide used for controlling annual and perennial grasses, as well as some broadleaf weeds, in crops such as corn, soybeans, cereals, turf, orchards, and non-crop areas including aquatic sites. It functions as a systemic herbicide that is absorbed by roots and shoots, inhibiting cell division and protein synthesis in susceptible plants, leading to disrupted growth and weed death. Applied pre- or post-emergence via soil or foliar methods, it provides effective weed management while offering relative safety to many broadleaf crops when used at recommended rates. Its environmental degradation is relatively rapid under aerobic conditions, supporting sustainable agricultural practices, and it is also utilized in research for developing advanced weed control solutions.
