Where can I get streptomycin fast?

Hello,
Michigan State University just sent notice of extreme fireblight risk in my area.
I am considering spraying streptomycin but don’t have any. Amazon is slow shipping at this time.
Is it possible to find streptomycin locally? Is fertilome fire blight spray common?
Will be calling a few nurseries tomorrow
Thanks

Do you have a Lowe’s or equivalent? That’s where I get it.

Used to buy it at “Southern States” co-op. Actually saw cedar apple rust and fireblight yesterday…some years never see any fireblight. The late ‘re-blooming’ attempts by some trees after the 23 degree night some had in April, and some more had in May…along with copious rainfall…and now the high dewpoints…must be the recipe for it.
