'Fungal' blight on Aristocrat ornamental pear.
I am very familar with "fire-blight" in pears BUT this is different. no "sheepards crook" no dark brown/black branch tips & reddis brown under the bark...
The tips are a lighter color & the leaves are brown. not responsive to a anti-biotic treatment....but stops further infection with a systemic fungicide.
The problem first came to my attention last summer (2011) & is very common this year.....any suggestions
