You have tweaked an interesting thought in my head.  I don't know how 
effective copper paint 
would be for fire blight, (which is actually a bacterial infection, with a 
Pseudomonas), but 
copper is unquestionably effective against fungal infections, such as 
cankers.  We sailors 
use a copper bottom paint as an antifouling on the bottoms of our boats, to 
inhibit the growth 
of marine creatures, (barnacles, seaweeds, etc.).  I wonder whether this 
would work to kill off 
cankers?  (It would be a lot more persistent than painting the canker with 
Bordeaux solution).  
Anybody ever tried this?
