    AZINPHOS-ETHYL

    RESIDUES

    Explanation

         The Codex Committee on Pesticide Residues requested the Meeting
    to reconsider the definition of the residue. The original data
    submitted to the 1973 Meeting1 and some additional data were studied
    and the relevant information is summarized in this re-evaluation.

    RESIDUES RESULTING FROM SUPERVISED TRIALS

         The residue data summarized in FAO/WHO 1973 indicates that the
    oxygen analogue either is not detectable or its concentration is lower 
    than 10 percent of the total residue.

         Methods used for the determination of residues in French beans,
    cauliflower and kohlrabi and cotton seed were suitable for determining
    the oxygen analogue separately. No residue was detectable. The other
    results were obtained with colorimetric methods, which measured the
    total residue. The low level of oxygen analogue in crops examined and
    the findings of the members of the Codex Ad Hoc Working Group on
    Methods of Analysis lead to the conclusion that the oxygen analogue of
    azinphos-ethyl does not contribute significantly to the total residue.

    RECOMMENDATION

         The Meeting concluded that the metabolites can be excluded from
    the definition of the residue. The maximum residue limits refer to the
    parent compound alone. The new definition does not alter the limits
    recommended previously.
