Thank you for your question, Lynne. Botritis blight and rust both cause spots; only the blight causes wilting. Here is a diagnostic description with control recommendations: https://pnwhandbooks.org/plantdisease/host-disease/blueberry-vaccinium-corymbosum-botrytis-blight
Note that the only fungicides available to homeowners are Bonide and Hi-yield Captan ("H"). Use per label instructions, in addition to the noted cultural controls. Good luck!
