I would like to use an organic solution. The fungal compost tea seems to stagnate the fungus but not get rid of it. I guess a biodynamic gardener would say, Make the trees happy and healthy and they'll defend themselves. They are mature apple and cherry trees. Any ideas? I've thought of copper or sulfur, but I have never used either.
Thanks,

PDX OR

In france Organic farmers are allowed to use Bordoux mixture ? A possibility maybe ?
