REP11/PR 8
FLUBENDIAMIDE (242)
77. The Committee decided to advance all the proposed draft MRLs for adoption at Step 5/8 noting the reservations of the
Delegations of the EU and Norway regarding the proposed draft MRLs for brassica (cole or cabbage) vegetables, head cabbage,
flowerhead brassicas; fruiting vegetables, cucurbits; legume vegetables, stone fruits due to the extrapolations used by JMPR and for
peppers; tomato and tea, green, black (black, fermented and dried) due to insufficient number of trials.
FLUOPYRAM (243)
78. The Committee decided to advance all the proposed draft MRLs for adoption at Step 5/8.
MEPTYLDINOCAP (244)
79. The Committee decided to advance all proposed draft MRLs to Step 5/8 and agreed that the source of the residue be
indicated for each proposed MRL. The Committee noted that the residue definition of meptyldinocap for MRL compliance was
corrected to align it with the JMPR recommendation.
THIAMETHOXAM (245)
80. The Committee decided to advance all the proposed draft MRLs for adoption at Step 5/8 in line with the recommendations for
clothianidin (238) noting the reservations of the Delegations of the EU and Norway regarding the extrapolations used by JMPR for
berries and other small fruits; brassica (cole or cabbage) vegetables, head cabbage, flowerhead brassicas; citrus fruits; fruiting
vegetables other than cucurbits; fruiting vegetables, cucurbits; leafy vegetables; root and tuber vegetables and stone fruits.
81. The Committee noted that the Delegation of Brazil would submit data and GAP for papaya to JMPR to support a higher MRL.
DISCUSSION PAPER ON THE APPLICATION OF PROPORTIONALITY IN SELECTING DATA FOR MRL ESTIMATION (Agenda
Item 6) 8
82. The Committee recalled that at its last session it had noted the concerns expressed by a delegation that JMPR had not
recommended MRLs for some commodities as application rates in supporting residue trials were more than 25% greater than the
critical GAP (cGAP) application rates (the JMPR/OECD cut-off point). The Committee agreed that the Delegation of Australia would
prepare a discussion paper to address the application of proportionality in selecting data for MRL estimation for consideration at its
next session. 9
83. The Delegation of Australia made a presentation based on the information provided in CX/PR 11/43/4 including practical
examples of application of proportionality based on types and rates of application, chemical/commodity combinations and associated
MRLs. The Delegation drew the attention of the Committee to the recommendation in the working paper by which JMPR could apply
proportionality in those cases where the residue data according to GAP were not sufficient for a recommendation. The Delegation
noted that this approach would give greater flexibility to JMPR in the use of residue field trial data and would allow MRL estimates to
be made in situations where the current ±25% rules excluded such estimates.
84. The Committee noted that there was general support for the application of proportionality by using supporting residue trials
with application rates beyond ±25% in those cases where the residue data according to GAP were not sufficient for a
recommendation. However, it was noted that this situation usually applied to minor crops and should therefore be limited to these
crops as opposed to major crops where availability of data usually allowed for normal residue evaluations. It was also noted that,
when applying proportionality, all data points under consideration, i.e. within/outside the acceptable range of ±25%, should be
adjusted to 1X to prevent issues of bias. It was further noted that the concept of proportionality should be further tested to ensure
reliable results before the Committee endorse this approach for use by JMPR. It would thus be helpful to gather information on what
compound/crop combinations the proportionality principles could apply, statistical methods used, number of tests needed, criteria for
application of the proportionality method, etc.
85. The FAO JMPR Secretariat informed the Committee that relevant information on the proportionality approach was provided by
the 2010 JMPR (General Consideration 2.8 of the 2010 JMPR Report). In this regard, the 2010 JMPR had also recommended
principles for use of proportionality, including general aspects, commodity and application types, etc. The 2010 JMPR Report also
presented examples on how to use these principles and the statistical method.
