I. Application and Amplification of General Seed Certification Standards

The General Seed Certification Standards are basic and, together with the following specific standards constitute the standards for certification of oats seed.

II. Land requirements

Land to be used for seed production of oats shall be free of volunteer plants. 

III. Field Inspection

A minimum of two inspections shall be made between the ear emergence and harvesting of the seed crop.

IV. Field Standards

A. General requirements

1. Isolation
