Chlordane Uptake from Soil by Root Crops 12

The incorporation of chlordane at a rate of 6 lb AI/acre into a sandy loam soil (12% clay) resulted in residues in beets, carrots, parsnips, potatoes and rutabagas of 0.03, 0.26, 0.24, 0.04, and 0.01 ppm, respectively. In these crops grown in another sandy loam soil (28% clay) the respective residues were 0.01, 0.07, 0.12, 0.15, and 0.01 ppm chlordane. The qualitative composition of the soil and crop residues as evaluated by the peak patterns of gas chromatograms did not change greatly during the 16-month period following chlordane application.
