    Any idea what disease is causing this?

    The bark is black and streaked, and there are cankers on the limbs. Often times there would be a ton of wasps around in the summer as well.

    Once identified, what would be the best course of action to clear and prevent further damage?

    Scale not cankers, and yes it is tulip poplar.

    The wasps are most likely the male's coming in to mate with the sedentary females. Unless you treat this winter with an oil spray and again in spring you will have an epidemic next year. Take care not cultural issues as well, mulch, water etc. No fdrtizer at this time. Take a same to your extension for positive ID of the scale and read this months issue of TCI magazine, there is a good article on scale in it.

    Okay, thanks for the information. So I need to look into some type of oil spray in the winter and spring? This tree has unfortunately been like this for probably 2-3 years.

    Hort oil winter early spring before buds swell. Later on imadacloprid and spreader/sticker either spray or root crown drench but only after flowering orhoney bees will be negatively affected.

    Looks like tulip tree scale, similiar to magnolia scale though I'm not as familiar with it's lifecycle as maggie scale.

    Oldoak is spot on, save the bees and other beneficials. Wasps and yellow jackets and ants may be there to collect honeydew.

    Now that you've become your own pest control applicator, you've got to read the label. That's going to tell you how to legally apply the material.

    Tree would be less stressed if it got pruned for structure. That species really likes 1 leader, not 3!!!
