  • Applications

    Propoxur (CAS 114-26-1) is a carbamate insecticide used across several sectors. In agriculture, it is applied to protect crops by targeting pests on fruits, vegetables, and cereals. In household and urban pest management, it is formulated into residual sprays or baits to control cockroaches, ants, and other nuisance insects. For stored products, propoxur-based formulations help prevent damage to grains and processed commodities during storage by reducing insect infestation. In veterinary applications, it is present in certain products for flea and tick control on pets and in some veterinary formulations, though usage is subject to local regulations and formulation limits.
