  • Applications

    Ethoprophos (CAS 13194-48-4) is an organophosphate pesticide used primarily in agriculture as a soil-applied nematicide and insecticide targeting root pests. Real-world applications include pre-plant soil treatment or incorporation into soil in granular or drench formulations to protect root systems from soilborne nematodes and root-dwelling insect pests across crops such as potatoes, vegetables, cereals, and fruit crops; it is used in both field and protected cultivation (greenhouses); it is commonly applied in soil-treatment programs to manage soil pests and nematodes at the root zone, subject to formulation specifics and local regulations.
