Cathy: first off, it is never a bother when somebody asks questions...I think we all love this site so much just because we can get good answers about almost any question from all the folks here.
Anyway, I'm gonna quote from the "Ortho Home Problem Solver" because I think it has a pretty decent answer to your question:
"After the infection has stopped spreading in the summer or fall, prune out and destroy infected twigs and branches at least 12" beyond visible decay. Sterilize pruning shears with rubbing alcohol after each cut. A protective spray of basic copper sulfate or streptomycin, applied before the blossoms open next spring, will help prevent infection. Respray at intervals of 5-7 days until the end of the bloom period. To prevent excess growth of shoots and suckers, avoid high-nitrogen fertilizers. Plant fireblight-resistant varieties."
And in a table, it lists some FB resistant varieties as: Baldwin, Empire, Prima, Priscilla, Stayman Winesap. So you might want to think about adding some of these varieties.
