Fireblight seems minor at first so many don’t take it seriously. There can be a late season strike here or there as shown here Late season Fireblight . To most people it might seem like much of the fruit could have been saved but with fireblight remove the infections asap it will get worse. That tree would have been killed within 2 weeks if it had not been grafted in the way it was to prevent that type of loss. You notice the fireblight landed on the tips of the branches you could tell at this stage how the infection occurred. Likely a bird landed on the branch in an infected orchard and then flew into my orchard and landed on a susceptible tree. Birds and insects land here from other places hundreds of times in a year but most of my trees are resistant and no infection occurs.
