Executive Summary

HED has been asked to further explain the Codex harmonization issues
with regards to cyprodinil for PP#1E7854.  Following are the crop
subgroups which needed further explanation on Codex harmonization.

Summary of US and International Tolerances and Maximum Residue Limits 

Commodity1	Tolerance (ppm) /Maximum Residue Limit (mg/kg)

	US	Codex

Onion, bulb subgroup 3-07A		0.60	0.3 onion, bulb

Caneberry  subgroup 13-07A	10	0.5 raspberries, red, black

Small fruit vine climbing subgroup 13-07F, except fuzzy kiwifruit	2.0	3
grapes

5 dried grapes (=currants, raisins and sultanas)

Vegetable, leafy, except brassica, subgroup 04A	50	10 lettuce, head,
lettuce, leaf

Fruit, pome, group 11-10	1.7	0.05 apple

1 pear



For all crop groups/subgroups except grape (which is the representative
commodity for Small fruit vine climbing subgroup 13-07F, except fuzzy
kiwifruit); the maximum residue in the magnitude of the residue studies
submitted to the US for support in establishment of tolerances was
greater than the Codex MRL.  For Small fruit vine climbing subgroup
13-07F, except fuzzy kiwifruit; the agency will harmonize and set a
tolerance at 3.0 ppm.  Along with the establishment of the tolerance for
Small fruit vine climbing subgroup 13-07F, except fuzzy kiwifruit; the
tolerance for grape will be revoked.  The tolerance for grape, raisin
will be increased from 3.0 to 5.0 ppm to harmonize with Codex.

The registrant will need to submit a revised Section F stating the
following:

Small fruit vine climbing subgroup 13-07F, except fuzzy
kiwifruit………3.0 ppm

Grape,
raisin…………………………………………………………
……..5.0 ppm

In addition, the acute dietary exposure analysis was revised to
incorporate the proposed increase in tolerances for grape and raisin. 
The chronic dietary exposure analysis did not need reanalyzed since
average residues were used.  A summary of the revised acute dietary
exposure is summarized below.
