  • Applications

    Dimethoate (CAS 60-51-5) is an organophosphate insecticide used in agriculture to protect crops such as fruits, vegetables, cereals, and ornamentals from a range of pests. It is formulated for field and greenhouse use as emulsifiable concentrates, wettable powders, and granules, supporting applications on orchard crops and in protected horticulture. It is commonly included in integrated pest management programs across production systems, with usage subject to local regulations and formulation limits.
