One of my Redbud trees is covered in wart like bumps. They flake off and are kind of oily. Anyone have any ideas about what I need to do? Call a tree company? Fungus?

Buy some SAF-T-SIDE Horicultural Oil and spray your RedBud.
Horticultural Oil Insect Spray is a concentrated oil that is mixed with water and then sprayed onto the leaves and bark of your tree to control a variety of insects. Among the insects it controls are: mites (such as spider mites), scale insects (such as magnolia scale and oystershell scale), galls, mealy bugs, codling moth, red spiders, whiteflies, aphids, leaf rollers, treehoppers and other insects.
During the Growing Season:
When sprayed during the growing season, Horticultural Oil Insect Spray kills insects by blocking their pores and smothering them. Mix at a ratio of 1:100 (one bottle makes 50 liters or 13 gallons of growing season spray).
During the Dormant Season:
When sprayed during the dormant season when trees and insects are inactive, Horticultural Oil Insect Spray remains an effective way to control dormant insects and eggs. Mix at a ratio 1:50 (one bottle makes 25 liters or 6.5 gallons of dormant season spray).
Our Horticultural Oil Insect Spray is a highly refined mineral oil much lighter than the old dormant-grade oils. It is also less viscous and evaporates more rapidly from leaves and stems of plants.
These features make Horticultural Oil Insect Spray much less phytotoxic (toxic to plants) and therefore more suitable for use during the growing season. It rapidly mixes in water and can be used in non-freezing weather as a dormant spray or at the recommended lower dosages as a summer spray on a wide variety of trees and shrubs.
The Horticultural Oil Insect Spray is recommended for use on fruit trees, shade trees, shrubs, ornamentals and roses. It is not recommend for use on Beech, Butternut, Colorado Blue Spruce, Douglas Fir, Hickory, Holly, Sugar Maple, Japanese maple, Walnut or ferns.

Thanks Burnet and Log. I will see if I can put my hands on some of that oil. Interestingly enough, the tree is in Lubbock, so maybe I should have it checked for STD's! Thanks again.

Ask the Agronomist(TM) says .....
Looks like a variety of scale insect to me .... the dormant oil burnet recommended will do them in. I usually advise hitting them in the late afternoon/early evening to avaid any potential damage of bright sunlight interacting with the oil on tender vegetation.

Definitely scale.
As another poster pointed out, spray oil and it will take care of it.

Thanks for all of the replies. I have sprayed the oil, but can I scrape the scale off of the tree? The leave little white spots on the bark after I've scraped a few of them off.
