Not currently a Certified Seed Grower?

Seed Certification is the process required to produce high quality pedigreed seed. Certified seed is a limited generation seed production system. Foundation seed produces Registered seed, Registered seed produces Certified seed and Certified seed produces grain or another commodity.

If you would like to become a certified seed grower, it is as simple as contacting the Texas Department of Agriculture (TDA). There is no charge to register as a certified grower. You will be interviewed by the TDA crop inspector for your county and will need to complete the State Certified Seed Grower Application [RSC-1202]:


Be aware of the basic requirements:

1. Cleanliness. To prevent contamination from other crops, varieties or weed seeds, all planting and harvesting equipment and storage facilities must be clean.

2. Seed eligibility. Foundation or Registered seed must be planted for the crop to be eligible for certification. Remember to retain the seed tag as proof of eligibility.

3. Ground eligibility. The seed must be planted on ground that has not produced a like crop in the past year unless it was planted to a class of certified seed of the same variety. Ensure there is adequate isolation of the proposed planting field from other crops of the same kind.

4. Field inspection. The field must be inspected by a TDA inspector prior to harvest. Prepare the field for inspection by roguing any contaminants or off-type plants and controlling any noxious weeds. Be sure to submit an application for field inspection by the appropriate deadline. Get the TDA Application for Field Inspection:

5. Seed conditioning and analysis. Use your own seed cleaning equipment to remove impurities (broken seed, chaff, weed seed, etc.) from your seed or use the services of a state approved conditioner. After cleaning has been completed, a sample of seed must be submitted to a TDA Seed Lab for laboratory analysis. See the TDA procedures and fees for submitting seed samples for testing:

6. Seed tags. For certified seed to be sold legally, both bagged and bulk seed require official TDA seed tags. Get the TDA Request for Certification Labels:
