Recommendations

Since methamidophos has been listed by the CCPR as a candidate for periodic review but not yet scheduled, and in view of the difficulties encountered by the present Meeting in evaluating the available data without the original studies, the Meeting recommended that the CCPR should schedule methamidophos for periodic review.

The Meeting estimated the maximum residue levels shown below for methamidophos on the basis of the residues found in supervised trials with applications of methamidophos and acephate.

Definition of the residue for compliance with MRLs and for estimation of dietary intake: methamidophos.
