Rick, I agree with your contol study. Something to think about would be for you and I to run a group of 10 Casa Blanca clones in a row sometime and do 5 treated vs 5 untreated (after symptoms) for a period of 3 years so. We could work up 20 scales this fall if you would like to do this.
But I really like Connies concept of getting many different views of many different cultivars from such a broad base that only a forum like this would provide. I'm very interested in both these ideas!
