The mobility of some organophosphorus sheep dip insecticides in soil

摘要

AbstractThe technique of soil thin‐layer chromatography has been adapted to permit the use of repeated or prolonged irrigation procedures so that the mobility characteristics of relatively non‐mobile insecticides may be studied. The procedure has been used to study the relative movement of organophosphorus insecticides such as chlorfenvinphos, trithion, delnav and dichlofenthion which are widely used as sheep d
