Used primarily as an insect growth regulator in agriculture and public health programs. It controls a wide range of insect pests by inhibiting chitin synthesis, which prevents proper formation of the exoskeleton during molting. Commonly applied in crop protection against lepidopteran pests such as caterpillars, as well as in forestry and horticulture. Also used in mosquito control programs to target larval stages in breeding sites, helping reduce vector-borne diseases like malaria and dengue. Its selective action makes it less toxic to non-target organisms, including beneficial insects and mammals, when used as directed.
