Residues of Aldrin, Chlordane, Endrin, and Heptachlor in Peanuts Grown in Treated Soil1

Dieldrin Translocation and Accumulation in Corn1

“…Dieldrin has been detected in . the green vines, hulls, and nut meats of peanuts grown on aldrin treated soil (1,9) and throughout pumpkin plants grown in a silt loam soil containing 2 ppm of dieldrin (5). The fruit, seeds and rinds contained higter dieldrin concentrations than the pulp.…”

Residues in three peanut varieties grown in dieldrin treated soil

“…The persistence of this and other organochlorine insecticides in agricultural soils is well known (Wilkinson et al, 1964) and crop residues from this source will continue to appear. Morgan et al (1967) reported that 0.02 to 0.08 ppm of dieldrin remained in soil 15 mo following soil treatment with aldrin at 2 kg per hectare. Whole peanuts grown in the same soil contained 0.03 to 0.09 ppm of dieldrin residue.…”
