Mobility Studies of 14C-Chlorpyrifos in Malaysian Oil Palm Soils

The mobility of 14C-chlorpyrifos using soil TLC was investigated in this study. It was found that chlorpyrifos was not mobile in clay, clay loam and peat soil. The mobility of 14C-chlorpyrifos and non-labelled chlorpyrifos was also tested with silica gel TLC using three types of developing solvent h...
