Check out this site, I think it may be the Jackpot I have been looking for for organic pesticides.

Good info there. I would limit the use of Pyrethrins though. They're low tox and short residual but they'll smoke your beneficial population along with the eggs so they can be very slow to recover.

Also in the landscape Streptomycin is of limited value. It works well but your window of opportunity is so short that it's not practical. When conditions are ideal for fire blight infection a farmer can tank up and spray on short notice and as many times as they need to (excluding costs).

Chrysanthemum/pyrithrins where used by the Egyptians, a looooong time ago, try and get the natural predators (micro herd) to get at them first, you would be amazed at the speed that they can kill
