What's going on in Seed Certification

Signup deadline has passed for most crops. It's not to late to sign up your fields, you will just incurr a late fee. Hurry and get them in!

Ground inspections for certified fields, and seed stock inspections have started! 

Remember: For Certified crops isolation flags should be placed when you sign the crop up for inspection. We highly recommend you double check them prior to flight inspections starting, since they can get knocked down or the crop may grow taller than the flags. 

Approximate start dates for helicopter inspections are: 

South Valley - 5/19

Washington/Yamhill/Multnomah - 5/21

Marion/N. Linn - 5/26

Clackamas/N. Marion - 6/1 



It's official, OECD lot size limit has been increased to 55,000lbs (with a 5% tolerance) for most grass seed species. See the announcement from Seed Certification manager Dennis Lundeen HERE.
