Long term persistence of parathion in soil

Abstract

PARATHION, an early organophosphorus insecticide introduced commercially in 1947, is, like most other compounds in this group, considered to be relatively non-persistent on plants and in soil. West1 reported its persistence to be 5-12 days on plants, and Lichtenstein2 showed that 97% of a soil application disappeared within three months. © 1971 Nature Publishing Group.
