Does anyone have experience dealing with blueberry leaf rust? I've had a very serious outbreak this fall that's been especially hard on my northern highbush varieties. I've read a number of fact sheets, etc., and it would appear that there are no fungicides registered to combat blueberry rust. It's well above nuisance levels for me, so I think I'm going to need to do something proactive. There are no hemlocks or native vaccinium around, so that's a plus. Beyond leaf clean up, though, has anyone had success with any product in particular?
