Form C "Request for Testing and Certificate of Inspection" must be submitted to the OCIA Office.  The grower must order OCIA samples bags, at no cost, from the association for submitting seed samples to the designated seed laboratory for testing.  Certification can not be completed until Form C has been submitted to OCIA and the official sample has passed testing.

To complete certification a 2 lb. representative sample is needed for wheat and other small grains.  One lb treated and 1 1/2 lb. untreated is needed for peanuts.
