is daybreak barberry affected by wilt?

Question

There are a lot of red cedar trees around here which makes it almost impossible to grow most barberries.

Answer 1

Although I've not seen disease on barberry plants, given the proper conditions, almost any plant can be affected by pathogens. The following link provides information on rusts on barberry: http://www.aphis.usda.gov/plant_health/plant_pest_info/barberry/
