  • Applications

    Metaldehyde (CAS 108-62-3) is primarily used as the active molluscicide in bait formulations to control slugs and snails in agriculture and horticulture; it also appears in consumer garden pest-control products (slug pellets) for home use, and is employed by professional pest-control services for crop protection and turf management in landscapes and urban green spaces, with use governed by local regulations and formulation limits.
