  • Applications

    Dichlorvos (CAS 62-73-7) is an organophosphate insecticide used for pest control across agriculture and storage environments. It is applied to field crops and in greenhouses to manage lepidopteran and dipteran pests; it is also employed as a fumigant or residual spray for stored products such as grains, cereals, and dried fruits to protect against infestations. In many markets, DDVP formulations are used for structural or warehouse pest control to defend facilities against flying and stored-product pests. Where allowed by local regulations, it may appear in consumer or professional household pest-control products, with use limited by formulation and regulatory guidelines.
