I entirely agree with Kari (Hi Kari!), The Terminal bud is the best solution for stopping fire blight. Once growth stops, you don’t have to worry about hail or anything else.
So at this point, I would also recommend waiting after harvest. You could consider keeping your picking staff an extra few days to clean up the fire blight if that’s possible. When trees are actively growing, different story: Quick Pruning is extremely useful when the first symptoms appear. We consider cleaning shears a hassle. It just slows down operations without measurable benefit. Making sure pruning crews are aware that they CAN spread the disease if they are careless is much more useful than sterilizing.
