Upon reconsideration, ARIA, in consultation with RAB1, has determined
that changes are required for the previous memorandum, D349398, D. Rate,
12/MAR/2008.  There are no changes in the original document other than
those explicitly set forth here.

Regulatory Recommendations and Residue Chemistry Deficiencies

Pending receipt of the revised Section F, revised Section B, revised
label and the forthcoming human health risk assessment, ARIA previously
recommended the tolerances of the combined residues of the herbicide
dichlobenil (2,6- dichlorobenzonitrile) and its metabolite
2,6-dichlorobenzamide in/on rhubarb at 0.06 ppm (DP Num: 315266, W.
Cutchin, 22/FEB/2006) and recommends the following tolerances for the
requested berry commodities at the levels listed below: 

Caneberry, Subgroup 13-07A	0.10 ppm

Bushberry, Subgroup 13-07B	0.15 ppm

The revised Reregistration Eligibility Decision (RED) (K. Boyle,
31/JUL/1996) recommended deletion of a stone fruit crop group tolerance
which was not being supported by the petitioner and establishment of a
separate tolerance on cherries.  However, as stated in the previous RED,
the stone fruit crop group was included in this dietary exposure
assessment since as long as the tolerance exists commodities containing
BAM residues could be imported (Dichlobenil: The Revised HED Chapter of
the RED, Case 0263, Chemical 027401, 027402 (BAM), K. Boyle,
31/JUL/1996,).

860.1200  Directions for Use

Conclusions.  The label is adequate to allow evaluation of the residue
data relative to the proposed uses on caneberry, subgroup 13-07A. 
However, the label should be revised for the bushberry, subgroup 13-07B
from 4 lbs ai/A to 6 lbs ai/A to match the Section B proposed use and
submitted data for the bushberry, subgroup 13-07B commodities.  Also,
the label and Section B must be revised to correctly spell the
commodities containing “currant” in the name.
