Schechter-Hornstein chemical assays of alfalfa treated at 6- inch height in 1959 with lindane spray revealed detectable residues at 28 and none at 35 days with 0.25 pound per acre, and detectable residues at 42 days after application with 0.5 pound per acre. Alfalfa-red clover treated in 1960 at 12-ineh height with 0.2125 pound per acre had detectable residues at 24 and none at 32 days. Bioassay using mosquito larvae indicated lower residues than chemical assay on the 1959 crop.
