Mesurol

Mesurol is a brand name for products containing methiocarb, a carbamate pesticide used in agriculture and horticulture to protect crops by controlling slugs and snails and by deterring birds from treated areas. Formulations are typically granular baits spread around plant beds or on soil surfaces, and some products are marketed specifically as bird deterrents when applied to seeds, fruit, or crop surfaces.

The active ingredient methiocarb acts as a cholinesterase inhibitor, disrupting nerve transmission in exposed organisms. In mollusks such as slugs and snails, this leads to death after ingestion; as a bird deterrent, treated materials are less palatable, reducing crop damage.

Safety and regulatory considerations: Mesurol can be toxic to non-target species, including birds, mammals, and aquatic life, and must be used only according to the product label. Handling typically requires protective equipment and attention to storage and disposal instructions. Because of environmental and wildlife safety concerns, methiocarb-containing products are subject to regulatory controls that vary by country and region, with some jurisdictions restricting or phasing out their use and others allowing professional application under license.
