Chlorbenzuron is primarily used as an insect growth regulator in agricultural settings. It interferes with chitin synthesis in insects, preventing proper development of larvae and pupae. This makes it highly effective against a range of pests including mites, thrips, leafminers, and certain caterpillars. It is commonly applied in fruit orchards, vineyards, and vegetable crops to control pest populations without harming beneficial insects when used appropriately. Due to its mode of action, it is often included in integrated pest management (IPM) programs where resistance management and environmental safety are priorities. Chlorbenzuron is especially useful in controlling pests that have developed resistance to other classes of insecticides, such as organophosphates and pyrethroids. It is typically applied as a foliar spray and offers good residual activity, providing extended protection after application.
