Red spots on leaves of blueberry bushes
I believe I have rust or blight on one of my blueberry bushes. Can I use Bordeaux spray on the bush? Should I treat the surrounding bushes. There is a hemlock tree nearby, possible vector? Will the rust cause the bush to lose berries this season? (it's loaded). Is copper sulfate fungicide ok to use on this plant at this time? The leaves appear to match pictures from several resources, so I think that is what it is. I look forward to hearing from you. Thanks

Could you send me a picture? I haven't seen rust on blueberries in the Valley? Let's make sure what it is before doing anything.
