Abstract:On experimental plots of peppers, residues of DDT were considerably higher on the plants than on the fruit. Doubling of the dosage did not necessarily result in doubling of residue on either plants or fruit. At 1 pound per acre the immediate average amount of DDT residue on fruit did not exceed the tolerance set (7 p p.m.); at 2 pounds per acre the tolerance was exceeded. Seven days after treatment the average amount of residue was below the tolerance except at the 2-pound rate with sticker spreader added. Residues of DDT on fruit were reduced by processing, and residues in the canned product were below the tolerance for the raw product. Seven days after treatment residues on pepper fruit sprayed with air blast equipment at 2 pounds per acre were well below the tolerance set for DDT.
