That about covers your options. Despite my opinion, I know some of you will still spray or maybe already have. Leave a small portion unsprayed and let me know what happens. Researchers will probably never do a decent scald or hail experiment, because we plan our projects early in the season and cannot count on these events happening. The hot weather we've had while fruit are sizing is ideal for the onset of upright dieback.
Vines generally recover, but it takes a few years to get back into production.
To prevent further stem gall, do not overfertilize with nitrogen, minimize beater damage, and protect vines from winter injury. Patricia McManus UW-Madison, Dept.

A couple of years ago we did some hail simulation experiments where we bruised the berries and made a single small hole in individual cranberry fruits and then dipped them in either sterile water or ditch water. We found that once there was a hole in the skin that fungicides were of no value in maintaining fruit integrity.
