Bonide Fruit Tree Spray Concentrate is not labeled for use on pear trees. After doing some research with universities and their studies there are not a lot of options for controlling fire blight on pears. Most recommend using right at the beginning stages of growth and emergence in the spring to start spraying regularly with copper fungicides. Monterey Liqui-Cop or Bonide Liquid Copper Fungicide would be good foliar options for the blight.
