Fireblight control begins with healthy trees. A tree with lesions in the
trunk might never fully (or even moderately) recover. After the active
fireblight season is over, prune your tree back several inches below any
sign of fireblight -- dipping the clippers in ammonia every time. Now
completely reinvigorate the soil down at least 2 feet at the drip line and
outward. Totally pamper this tree without over-fertilizing. Apply
Streptomycin in late fall in a several day lull between storms. Apply again
about 2 weeks BEFORE the tree blooms. Foliar feed regularly with nutrients
after the bloom. Keep an axe close by so that the tree knows this is its
last chance. Try this 2 years in a row. After that, consider the battle
lost -- the tree is systemically infected.

That Pomona fireblight article says, "The best spray to use so far is
Streptomycin, if you can find it. As far as I've been able to discover,
only big fruit growers can access Streptomycin."
I'm not sure how well Streptomycin will work for a small grower. About three
years ago at an Indiana Hort. Society meeting a commercial grower reported
he noticed the outside rows in the orchard didn't receive the same degree of
protection as the center of his orchard. He theorized bees coming in from
the outside brought in fresh bacterium whereas the center of the orchard
trees were visited by bees that had been across flowers with Strep. killing
what was on their bodies. Based on his report a few stand alone trees might
receive less protection as they would be more likely to receive continual
