I have occasionally mixed a bit of pyrethrin with a Daconil treatment with no problems (even though Ortho officially does not recommend doing so), but I can't answer the question as to mixing pyrethrin with the fungicides you've listed. Maybe try asking on the rose forum?

Those folks are totally up to speed in terms what can and cannot be used on roses. At least they were last time I looked over there...

Yes, I've mixed it many times with no problem. Be sure to add a spreader-sticker too.
