According to wikipedia there
are molecular mechanisms within copper that can control a wide range of
molds, algae, fungi, and microbes.
We've been cutting off new
tomato flowers to divert energy to fruit and I thought it might be a

few years ago.
If it slows down the blight
even a little it'll be worth the effort.
