The residues of pyraclofos (Voltage 50 EC) (0-l-(Chlorophenyl-pyrazol - 4-yl-o-ethyi S-n- propyl phosphorothioate) in cotton seed, lint, oil, and soil were determined 10 days after eight sprays at four dosages. The results indicated that residues were quite low, and hence the insecticide can be safely used on cotton crop without any risk.
