Suspected Fire Blight in young Pear Trees
I help run a community orchard in North Portland where I suspect fire blight has hit two of our trees. One is a Bosc Pear and another is a Seuri Asian Pear and both are about 2-3 years old. They are about 30 feet apart with several trees in between them. The disease is only showing up in the foliage (I can't find anything abnormal on the stems or branches). It's starting on the outer edge of the leaves and starts as an orange-red, then turns black, and then a crispy dried brown. There is very little leaf curl, and only a few leaves are completely infected (it tends to be just the outer edges). Nonetheless, about 3/4 of the foliage of the Bosc Pear is infected and almost half of the Seuri seems to be hit. I am going to drop by the orchard on Thursday and will take some photographs, but for now I found a couple of similar images online:
So wondering if this is indeed fire blight and if so is it worth trying to save these trees? There are a good number of other young pome fruits in the same area.
