Molluscicides are chemical agents that help eliminate mollusks, including snails and slugs. These pests can cause significant damage to crops and gardens and can also carry dangerous diseases. Several synonyms are available that describe different types of molluscicides. For example, ferrous phosphate is a popular anti-slug ingredient and is often listed on product labels as a derivative of molluscicide. Ferric phosphate is another type of molluscicide that is useful for controlling snails and slugs. Other synonyms for molluscicide include slug bait and snail killer. Ultimately, the choice of molluscicide type will depend on the target species and the application method.
