I have an Asian fruit tree that has a natural burk color that looks powdery white. Part of the trunk and a couple of stems that are now brown. It feels the same as the rest of the tree when you touch it. We have started to water it everyday in case it was a problem with water. We also bought disease liquid to dilute in the water. What could be the problem?

Watering everyday might be excessive. Asian pear trees do like moist soils but probably only need to be watered twice a week until the weather gets really hot. Every other day might be necessary during the summer months unless your soil holds lots of moisture. Asian pears are susceptible to a couple of diseases: fireblight, where the leaves remain on the branch and look burned and crispy, and bacterial canker where you'll see definite sunken or raised areas that look diseased. If you see neither of these symptoms, the branches may simply have died for no apparent reason. Fruit trees sometimes do this. I'd prune off the dead branches. Browning bark on the trunk sounds like a bacterial/fungal disease; overly soggy soil can cause the butt of the trunk to become waterlogged and turn brown. I'd be careful with watering. Since you've already purchased a fungicide, go ahead and use it according to label directions. I hope it stops the problem!
