If the leaves have died but remained on the tree, your Bradford pear may have fire blight which is a bacterial disease. If the leaves turned brown and fell off, a fungal disease might be the cause, or excess watering (poorly draining soils). It's really difficult to diagnose the problem without seeing the tree! Look for spots on the leaves or cankers/wounds on the branches and trunk. Probably the best way to get a real diagnosis is to take a sample of a branch and leaves to your local Cooperative extension office. Helpful folks there can inspect the plant parts under a microscope and either confirm or rule out my suspicions. Contact Texas Cooperative Extension, 3151 Southeast Inner Loop, Georgetown, TX 78626 phone (512) 943-3300. Good luck with your pear tree.
