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.

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."
Hello all,
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 fresh inoculum.
