Can you describe the journey of plant material from the time that it arrives at CPCNW to the time that you are releasing it as clean material?
9:07
Um, sure.
9:08
Um, it's actually pretty, um, satisfying to walk through the, the process.
9:12
Um, it happens in, uh, three different phases.
9:17
So the first one is, uh, diagnosis, and the second one is treating, and then we verify.
9:24
That means we retest again before we, uh, either maintain in our repository or release it back to the, um, the nurseries or, uh, custom propagators.
9:35
When the material first arrives into the CPCNW, um, it may be a new grape variety or a cherry variety that, uh, a breeder just developed and wants to, uh, get introduced, um, or like a hop cultivator, uh, coming from maybe another state or another country.
