Influence of exogenous organic matter in the mobility of diazinon in soils

The mobility of diazinon (O,O-diethyl-O-2-isopropyl-6-methylpyrimidin-4-yl phosphorothioate) in soil columns modified with three organic amendments and with hexadecyltrimethylammonium bromide was studied. Based on the percolation curves and residual pesticide partitioning in the columns, all four am...

Summary:The mobility of diazinon (O,O-diethyl-O-2-isopropyl-6-methylpyrimidin-4-yl phosphorothioate) in soil columns modified with three organic amendments and with hexadecyltrimethylammonium bromide was studied. Based on the percolation curves and residual pesticide partitioning in the columns, all four amendments reduced leaching of the pesticide from soil. The effect was found to be related to the nature and carbon content of the amendments, the presence of soluble fractions in them and the soil texture.
