A. Field Inspections. Two inspections shall be made of the growing crop, the first at early blooming stage and the second just before harvest. Only one inspection shall be required in the case of open-pollinated varieties.

B. Field Standards

1. Sunflower seed grown for certification shall not be on land that was planted the previous year to sunflower of another variety.

2. The isolation distance between varieties for all classes shall be at least 2,640 feet.

3. Flowering. In a crossing field for the production of hybrid sunflower seeds, the male parent must be in bloom and producing pollen at the time the female parent is in bloom. If the female sunflower heads produce pollen before the male parent heads, then the female pollen must be removed to prevent cross-pollination.

4. Maximum Impurity Tolerances (maximum limits per 1,000 plants)
