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 

Making sure pruning crews are aware that they CAN spread the disease if they 
are careless is much more useful than sterilizing.
