Metaldehyde 99% TC Liquid is a highly concentrated technical-grade molluscicide presented in a stable liquid form. It is primarily used for the formulation of molluscicide products to control terrestrial slugs and snails, particularly in agricultural, horticultural, and ornamental crop applications. Metaldehyde works by disrupting the mucus production system in slugs and snails, leading to dehydration and death.
Its liquid technical concentrate form offers improved solubility for manufacturing various formulations such as liquid baits, granular baits (after further processing), and ready-to-use sprays. Metaldehyde is particularly popular for use in crops such as vegetables, cereals, ornamental plants, and fruit crops where slugs and snails cause significant damage.

Metaldehyde is a contact and stomach poison for slugs and snails. It affects their mucous cells, causing excessive mucus secretion, leading to dehydration. It also impairs motor control and feeding activity. Death typically occurs within 1 to 2 days after ingestion. The active is highly effective even at low doses and under variable environmental conditions.
Agricultural Use:
Protects crops such as lettuce, strawberries, cabbage, maize, and oilseed rape from slug/snail damage
Horticultural Use:
Applied in flower beds, nurseries, and ornamental plant environments
