FENAMIPHOS     JMPR 1978

    Explanation

         Fenamiphos was evaluated by the 1974 and 1977 Joint Meetings
    (FAO/WHO, 1975a, 1978a).

         At the 10th Session of the Codex Committee on Pesticide
    Residues (Alinorm 79/24: para. 163) the delegation of Australia
    indicated that they had data which supported a higher MRL for
    carrots than that proposed (namely 0.05 mg/kg at limit of
    determination). The evaluation of these data is covered by this
    monograph addendum.

    RESIDUES IN FOOD AND THEIR EVALUATION

    RESIDUES RESULTING FROM SUPERVISED TRIALS

         Data were obtained on residues arising from the use of
    fenamiphos on carrots in Australia where the present authorised
    rate of application is 9.6 kg/ha. These data are shown in the
    table.

    RECOMMENDATIONS

         On the basis of the new residue data obtained from Australia,
    together with the data evaluated at earlier sessions of the Joint
    Meeting the following amended MRL for carrots is recommended. The
    limit is for the sum of fenamiphos, its sulphoxide and its
    sulphone. This definition of the residue now also applies to
    previous recommendations, which were formerly for "the sum of
    fenamiphos, its sulphoxide, and its sulphone, expressed as
    fenamiphos".
