This won't answer your question, but might give you ideas for the future.
I start spraying my apple trees for rust two to three weeks before the last frost date. I spray them every 10 days, but not during bloom. It has been my experience that once they get it, you cannot cure it for that year.
Pear trees are the only trees that need to be sprayed during the bloom (in my experience, at least) for fireblight.
I did spray before the last frost date (also pre bees) but we've had so much rain that most applications were washed away. Grrr. The good news is that the neighbor took out his cedars, so maybe the problem will slowly diminish. Fascinating disease, but not fair that it damages apples more than cedars.
