First of all, FB is like cancer, the quicker you deal with it the better, be 
walking and checking every morning,  then when you find it, look for the growth 
rings and be sure to cut back of the growth ring, ahead of them is a waste of 
time. be looking for the subtle change of color from heathy green to sickly 
green  on shoot tips. Lee Elliott Upstart Nursery, Winchester, Il

 Doug- where are you located?
 What rootstock(s)?
 What cultivars?
 How old are the trees in your tall
 spindle?
 What was your fireblight control
 program at bloom? 
 any post bloom program(s)

 Doug, it's sort of complicated. First,
 you probably know the bacteria travels from the tip
 downwards. The idea is to cut well below where the infection
 has traveled. You can cut away some bark and see where the
 brown area meets green cambium. I cut pass this point - well
 past it. I'm guessing I would cut about three times the
 length of the affected area. For example, if the tip has
 died back 6 inches, I would remove 18 inches of that limb.
 This is my gut but but this has worked for me in the past. I
 don't know the extent of your knowledge, but you need to be
 careful not to spread the bacteria with your tools and
 hands. Some people dip their tools in alcohol or Clorox
 between cuts. I use Clorox wipes on my shears, making sure I
 use a fresh wipe almost every cut, as the wipe ought to be
 very wet. On small limbs, say a quarter of an inch or less,
 I rip the limb off. The big thing is, take action
 now!!  With warm weather you can get a lot of damage.
 If you burn the limbs, don't l
  et the smoke drift into your orchard -
 something a guy told me....

 Pruning out fire blight this time of
 year can be tricky depending how much fire blight you are
 pruning out.  Excessive pruning will encourage more
 shoot growth = more shoot growth means susceptible shoots to
 fire blight right now especially with conditions favorable
 for disease.  Trees should be hardened off right now
 meaning new shoot growth should be finished.  When this
 occurs, the bacteria stops moving in the trees and new fire
 blight incidence should stop.  I would highly recommend
 avoiding doing anything that would encourage new shoot
 growth right now.  If it were me, I would just wait
 until the dormant period to aggressively remove
 everything.  There is much debate about cleaning
 pruning shears between cuts.  I don?t recommend it
 because the bacteria can move 3 feet beyond the site of
 visible infection, so disinfesting is a moot point. 
 Here is my latest article (June 26, 2018) in Penn State
 Fruit Times about what to do about fire blight now (it?s
 just below the info a
  bout apple scab):
 
 https://extension.psu.edu/mid-season-tree-fruit-disease-update
 
 And a note: do not spray any
 streptomycin.  Streptomycin is for bloom time only, and
 after a trauma event, such as hail. Do not spray it beyond
 these times.  If you are concerned about new shoot
 growth (if this is a new orchard pushing right now), I would
 recommend Cueva to limit spread of shoot blight.
