Disease on moonglow Juniper trees

I am having trouble with my moon glow juniper trees that are 3 to 4 years old. They have Multiple branches that are turning orange and dying. I have been treating them with a copper fungicide every two weeks and one other broad-spectrum fungicide with minimal improvement.
any other recommendations on what I can do to help save them? I have been pruning the dead branches to try to minimize spread of infection as well.

I read that a tablespoon of castor oil and a tablespoon of dish soap diluted with a gallon of water in a sprinkling can can be used to tread the soil in a vegetable garden to prevent voles. We have a vole infestation in our community garden which is organic. Will the castor oil diluted in this fashion harm the veggies or make them taste bad?
