BEAD Response: As noted in the header ofall PRD Label DataReports, this report contains aggregated label data and represents label data from all prometryn registrations. See BEAD's responses below for each bolded annotation inthe Syngentatable: Carrots, Celeriac and Okra BEAD agrees thatthe informationprovided by Syngentafor carrots, celeriac and okrareflects the label use information for Caparol 4L. However the datareflected inthe PRD Label Data report are aggregated and not specific to this product. No change to the PRD Label DataReport is needed as a result ofthese suggested modifications. Coriander BEAD agrees thatthe a.i. maximum application rate per crop cycle of 1.6 lbs. a.i. /a ofCaparol 4L for coriander is correct. The PRD Label Data Report has beenupdated to reflect this rate. Cotton BEAD agrees that the a.i. maximum application rate per application is 2.8 lbs. a.i. 

### I a. This rate is represented inthe PRD Label DataReport. BEAD also agrees with the 5.95 lbs. a.i. 

### I a max app rate per year. The PRD Label DataReport aggregates label data based onthe highest single maximum application rate, not onthe highest maximum application rate peryear. No change to the PRD Label DataReport is needed as a result ofthese suggested modifications. Leafy Vegetables BEAD agrees with Syngentaregarding the a.i. maximum application rate per application of2.0 lbs. a.i. 

### I a. This rate is represented onthe PRD Label DataReport and reported under the celery use site. The 40 days pre-harvest interval reflects a non-Syngentaregistration. No changes to the PRD Label DataReport are needed as a result ofSyngenta suggested modifications. 2Sources:
