A young pear try that I purchased in Spring and planted up immediately always had droopy foliage. I assumed that was a varietal habit. However, in recent days it has developed black and brown marks on the foliage and the droop has become more prounced. I am concerned it might be fireblight as it is planted among 25 more apple, pear, plum and cherry trees. Is my diagnosis correct (see attached photo)? Will it spread? Shoud I remove the tree and burn it? The variety is William Bon Chretrien.
It could be a root rot disease in the root ball that never allowed it to leaf out fully, and has got worse.
It’s a relatively new plant and the garden centre might take a view on it.
It is unlikely to survive,
