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?
