This is the 3rd year for my grav apple & Bartlett Pear. I though this long cold wet Spring might be trouble, & now my beautiful big pear and apple have fireblight. I keep amputating, and I keeping getting more affected branchs. Does this thing quit when the weather gets drier and warmer? Or am I going to be chopping and chopping til there is nothing left of my trees? If they do survive, I want to take preventive measures from now on, but heard antibiotic sprays are becoming less effective, as the Fireblight builds up a resistance to it.

Thanks in advance for any advice I can get.
