CRB to Host New Assessment Form Trainings

Effective October 1, 2017, deliveries to packing houses will need to use a new CRB assessment form. The form will be available on the CRB website as we are creating a new database to allow for the electronic submission of forms. The changes can be explained in three factors:

  1. Please submit organic production separately from conventionally produced citrus. We have developed two different forms: one for each type of production.
  2. Please submit your production as delivered from each of the three production districts.
  3. Please submit your production by the detail of varietal type and cultivar as afforded on the respective assessment form.


Please note that the data being supplied is distributed in an accumulated form to assure confidentiality for every grower.

The Citrus Research Board is conducting a series of meetings to present the assessment form changes. The meeting is geared toward packing house managers and assessment administrative staff. Please find information about meeting dates, times and locations below.
