Documented applications: Uses: Used for control of snails in seed crops, turf, ornamentals, berries, citrus, vegetables, and other crops, [Reference #1] Used for synthesis in the chemical industry, as odor agent, and as pesticide, [IUCLID] Used as molluscicide, solid fuel for small heaters (alcohol replacement), and fire starter, [Reference #2], Farming (Pesticides) [Category: Industry], For metaldehyde (USEPA, OPP Pesticide Code: 053001) ACTIVE products with label matches., SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses., Metaldehyde is a molluscicide used to control snails and slugs on a wide variety of sites, including turf, and vegetables., In compressed form as a fuel instead of alcohol, molluscicide., Polymer, Metaldehyde is used as a pesticide against slugs, snails, and other gastropods, it is also used in tablets as a solid fuel for small heaters, and as fire-starter. (L1782), Use Classification: Molluscicides, Environmental transformation -> Pesticides (parent, predecessor), Household Products: Information on 12 consumer products that contain Metaldehyde [BSI:ISO] in the following categories is provided:, • Pesticides, Information on 4 consumer products that contain Metaldehyde in the following categories is provided:, Methods of Manufacturing: Metaldehyde is obtained in addition to large amounts of paraldehyde during polymerization of acetaldehyde in the presence of HBr and alkaline earth metal bromides, such as CaBr2, at temperatures below 0 °C. However, yields are scarcely higher than 8%. Yields of 14 - 20% have been reported when working in the presence of 7 - 15% of an aliphatic or cyclic ether at 0 - 20 °C. Insoluble metaldehyde is filtered out. Acetaldehyde is then distilled from the filtrate following depolymerization of the paraldehyde and is returned to the polymerization. Recycling of the large amounts of acetaldehyde results in losses that increase the process costs., Prepd by polymerization of acetaldehyde in presence of hydrochloric acid, sulfuric acid @ low temp: Kekule, Zincke, Ann 162, 125 (1872), in presence of pyridine and hydrogen bromide: Wilder, US patent 2, 426, 961 (1947 to Publicker Ind)., Formulations, Preparations: Corry's Slug, Snail & Insect Killer, Get-A-Bug Snail, Slug & Insect Killer : Active ingredients 2.0%Metaldehyde, 5.0% Carbaryl, Bug-Geta Snail & Slug Pellets: Active ingredient 3.25% Metaldehyde, Durham Metaldehyde Granules 3.5: Active ingredient 3.5% Metaldehyde, Corry's Liquid Slug & Snail Control, Deadline Bullets, Deadline M-PS Mini-Pellets!, Metaldehyde 4 Bait, Metarex 4% Snail And Slug Bait: Active ingredient 4.0% Metaldehyde, For more Formulations, Preparations (Complete) data for Metaldehyde (29 total), please visit the HSDB record page., U.S. Production: Production volumes for non-confidential chemicals reported under the Inventory Update Rule.
