Submit Samples to the WSU Resistance Testing Program

Submitting a sample to the WSU Resistance Testing Program is easy. The best approach is to put a few coin envelopes (size A4 is best) in the combine or your scouting rig. The amount of seed required for testing varies for each species – we need several hundred seed if possible. Put this envelope in another envelope or a small box for mailing and do not use plastic bags.

Make sure the sampling occurs across the area of interest, not just at one spot. If you are interested in the entire field you need to sample the entire field. If you are looking at a small patch, sample throughout that area. Print out a submission form and include it with the sample. If you include an email, you’ll receive updates including confirmation of receipt.

Send in those samples!
