(Pseudomonas syringae pv syringae): On barley. Usually only upper leaves attacked. Small water soaked lesions form that will eventually coalesce to larger lesions that may cover entire leaf. Not common. Generally found associated with sprinkler irrigation in cool wet weather. Treat seed with copper hydroxide seed treatments (this is a generic active ingredient available in several formulations).
