Deb, propiconazole is never listed for black rot treatment so its a bit 
surprising that it worked for you.  I used copper for several years but it 
required 3-4 sprays and its not good for the soil to all add that copper.  I 
used Kocide 3000.  My guess of why the bordeaux was not working Jerry is you 
did not apply it often enough.  Now I just use one spray of myclobutanil 
around when the grapes are flowering and I get good enough control.  
Myclobutanil (Nova, Eagle, etc brand names) is not organic but I feel it is 
less damaging than adding all that copper to the soil.
