I try to buy pear and apples that are disease resistant as possible but you are at the mercy of information that you can gather. I planted 10 pear trees from The Wildlife Group 7 years ago and have had a several pears the last three years but they have really developed into nice and loaded trees this year. Went to the farm today and Becton and Gate are both full of fire blight. I only bought pears which were advertised as never seeing fireblight in them, but I know the word immune was not used just never seen. The other varieties are standing amongst these two and seem clean. My point of this post is no hard feelings but If you are conscientious about avoiding trees that will get fireblight then I would avoid these two.
