STUDIES OF THE MOBILITY OF PESTICIDES BY SOIL THIN LAYER CHROMATOGRAPHY

Abstract
The influence of certain additives on the mobility of pesticides was studied by means of a simplified technique. The variations in the Rf values of insecticides phosphamidon (Dimecron), DDVP, malathion, ziram and zineb, with changes in pH and organic matter and additions of CaCO3, cationic, anionic and nonionic surfactants to the soils are reported and explained on the basis of adsorption.
