Resistance Testing Program

Sample submitted to 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.
