The disease may advance and cause branch die-back.

Apply a dormant spray with horticultural oil and fixed copper during the winter, a mixture of products like this, according to label directions:

Pear trees can also get 'fire blight' a bacterial disease that enters through the flowers. Stand by weekly with a pole pruner and cut out blackened, "shepards crook" wilting tips below the blackened stem area, as they appear.
Attend to pruning, soil fertility and water management and mulching, and you may start to get some fruit.
Here's my favorite complete mineralized organic fertilizer:

second choice may be available in your local garden center: Down To Earth or Dr Earth all purpose:
