Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Mevinphos is an organophosphate insecticide that acts as an acetylcholinesterase inhibitor to control insects in a wide range of crops. It is most commonly used for the control of chewing and sucking insects, as well as spider mites.
Manufacture[edit]
Mevinphos is produced by the reaction of trimethyl phosphite with chloroacetoacetate.[1]
