  • Metaldehyde is an organic compound with the formula (CH3CHO)4.
  • It is commonly used as a pesticide against slugs, snails, and other gastropods.
  • It is the cyclic tetramer of acetaldehyde.
  • Metaldehyde is a white crystalline substance isomeric with, and obtained from, acetic aldehyde by polymerization, and reconvertible
    into the same.
  • Metaldehyde (C8H16O4) is not a complicated chemical. In its base form, it is a white crystalline powder that does not dissolve in water.
  • Metaldehyde is obtained in moderate yields by treatment of acetaldehyde with various acid catalysts, such as hydrogen bromide.
  • The reaction is reversible, upon heating to about 80 °C, metaldehyde reverts to acetaldehyde.
  • Metaldehyde exists as a mixture of stereoisomers, molecules that differ with respect to the relative orientation of the methyl groups
    on the 8-membered ring.
  • Metaldehyde is a selective pesticide used by farmers and gardeners to control slugs and snails in a wide variety of crops.
  • Metaldehyde-containing baits should be used with caution as they are toxic to dogs and cats.
  • Metaldehyde is also used as a camping fuel.
  • Metaldehyde is a molluscicide used to control snails and slugs on a wide variety of sites in agriculture and home gardens, including fruit and vegetable crops, ornamentals, lawns and turf.
  • Metaldehyde may be applied with ground equipment by professional applicators.
  • Domestic users can apply metaldehyde by hand to soil surfaces in and around home gardens.
  • There is limited removal of metaldehyde using standard pesticide removal techniques of ozone or granular activated carbon (GAC).
  • Metaldehyde is used in Washington table beet seed production.
  • The maximum level of metaldehyde in treated drinking water reported to DWI to date is 1.03 μg/l.
  • Farmers apply around 250 tonnes of metaldehyde (an active substance in slug pellets) to agricultural land every year. It helps to protect cereal, oil seed rape and other crops from slug damage.
  • More recently, other companies in the midlands, eastern, south east and south of England have detected metaldehyde in raw waters.
  • Metaldehyde is the active ingredient in most snail and slug baits, and has been in use in Australia for many years.
  • Metaldehyde is contained in slug pellets used by 80% of farmers applying a molluscicide as part of their control strategy for the UK’s most damaging pest. It is reported that slugs account for 70% of all crop pest problems.
  • Metaldehyde is a very important chemical in grass seed production in western Oregon.
