II. Land Requirements Land to be used for seed production of carrot shall be free of volunteer plants.

A. Mother root production stage

A minimum of two inspections shall be made as follows:

3. The first inspection shall be after 20-30days of the sowing in order determine isolation, volunteer plants, off types including bolters and other relevant factors.

4. The second inspection shall be made after the mother roots have been lifted to verify the true characteristics of roots.

B. Seed production stage

A minimum of four inspections shall be made as follows:

1. The first inspection shall be made before flowering in order to determine isolation, volunteer plants, off types including bolters and other relevant factors.

2. The second and third inspections shall be made during flowering to check isolation, off types and other relevant factors.

3. The fourth inspection shall be made at maturity to verify the true nature of umbels.


IV. Field Standards

A. General Requirements

1. Isolation Carrot seed fields shall be isolated from the contaminants shown in column 1 of the Table below by the distances specified in column 2, 3, 4 and 5 of the said Table.
