How Long Does Tree Spray Need?

 
I've been wanting to spray my small orchard for three days now, since

the petals fell, but it's been too windy. I'd hoped the wind would die
down this evening, Thursday, but no luck. I'll try tomorrow evening,
when I get home from work.

They're predicting thunderstorms Sunday afternoon. So if I spray
Friday evening and it rains Sunday afternoon, about 40 or so hours
later, will the bug spray and fungicide have had enough time to do
their job before washing away? What's the minimum time needed between
spray and rain?

The label is the law, so read that first.  A day without rain is
generally enough.
