  • Applications

    Chlorpropham (CAS 101-21-3) is primarily used as a sprout suppressant in stored potatoes and other tubers to extend shelf life by inhibiting sprouting; it is also employed as a herbicide in certain crop protection programs to control weeds; it serves as a chemical intermediate in the synthesis of other carbamate pesticides; in horticulture and greenhouse settings it has been evaluated as a plant growth regulator to limit shoot growth; formulations include encapsulated or vapor-delivery systems for storage applications.
