Well, I had heard fireblight wasn't that big an issue around here, and I have been trying to not spray unless I have some reason to and even then trying to stick with organic stuff. By the time I realized it was fireblight, it was already well into second year wood on two trees. I read that there isn't much you can do about it by that point regardless of what you are willing to spray. Following Scott's low impact spray recommendations, I'm going to do a copper treatment at green tip to pink next year and hope for the best.
As far as netting goes, I haven't had as much time for the garden this year and have not had such trouble with rabbits before this year. I guess I was hoping they would give up and move on. They don't seem to be eating stuff at this point and I haven't seen them lately, but they did a lot of damage in spring and early summer. They even ate rosebushes and other perennials at my neighbor's house, so the prospect of netting everything in my yard is not appealing. I'm thinking about limiting entry into at least the back next year by putting wire mesh against the bottom half meter of my fence and maybe making a box trap.
