Introduction: Metaldehyde is a molluscicide used to attract and kill slugs and snails. It is used in a variety of vegetable and ornamental crops in the field or greenhouse, on fruit trees, small-fruit plants, or in avocado or citrus orchards, berry plants and banana plants. It is applied to the soil around plants. Care should be taken not to contaminate edible parts of the plant. It is used in the form of granules, sprays and dusts, or mixed with bran as a bait. It works primarily in the stomach by producing toxic effects after it is ingested by the pest. Metaldehyde is available in pelleted baits.

ENVIRONMENTAL FATE

Breakdown in soil and groundwater: Metaldehyde is of low persistence in the soil environment, with a half-life on the order of several days. It is weakly sorbed by soil organic matter and clay particles, and is soluble in water. Due to its low persistence, it is not a significant risk to groundwater. Breakdown in water: Metaldehyde undergoes rapid hydrolysis to acetaldehyde, and should be of low perstistence in the aquatic environment. Breakdown in vegetation: Many types of flowers lose their color when they come in contact with metaldehyde dust or spray. 

Usage: Metaldehyde is applied as a molluscicide bait for controlling slugs and snails in a very wide range of agricultural and horticultural crops, and by members of the public to control slugs and snails in their gardens and allotments.

Application: Mode of action Molluscicide with contact and stomach action. Metaldehyde-poisoned slugs secrete large quantities of slime, desiccate and die. Their mucus cells are irreversibly destroyed. Uses Metaldehyde is a molluscicide used in a variety of vegetable and ornamental crops in the field or greenhouse, on fruit trees, small-fruit plants, or in avocado or citrus orchards, berry plants, and banana plants. It is used to attract and kill slugs and snails. It is applied in the form of granules, sprays, and dusts, or pelleted or grain bait, typically to the ground around the plants or crops. It works primarily in the stomach by producing toxic effects after it is ingested by the pest.
