Wheat seedlings grown in Lakeland sandy loam soils treated with dieldrin‐ 14 C and DDT‐ 14 C absorbed and translocated 14 C residues to the shoots. Based upon 14 C, dieldrin residues in wheat increased in direct proportion to soil application rate. 14 C concentration in wheat was approximately 18% of the soil dieldrin‐ 14 C content, whereas the range of 14 C from DDT‐ 14 C was from 3 to 10% of the treated soils. Soybeans, grown to maturity in endrin‐ 14 C treated Lakeland and Hagerstown soils, absorbed and translocated endrin‐ 14 C to the hay and seeds. Absorption from the Lakeland soil was twice that from the Hagerstowns oil. However, seed residues were essentially the same. 14 C equivalent of endrin in the seed was 0.12 ppm. Endrin residues in soybean shoots increased linearly with time. Radioactivity from extracted soybean hay was identical to that of authentic endrin‐ l4 C, when measured qualitatively by thin‐layer chromatography.
