- Two Anjou blocks were sprayed on the same day. All rates were the same with exception to the NanoPro. Check vs trial.
- Check (201 Larson Ranch)
- Trial (102 A Ranch)
- The NanoPro was mixed in with the Ultor and then the adjuvants were added.
- Application was done on a Thursday (June 30th) and tissue samples were pulled on Tuesday (July 5).
- 8 new shoots per block were pulled at 10:00 AM, the leaves were washed, patted dry and then shipped overnight to Pacific Ag Labs for AI testing.
