Scale insects
Looks like a soft scale insect on the oaks. A Imidacbrid product --used as a soil drench should work-But you need to read the label about the insects it controls and follow the instructions. Leacium soft scales they look like-but my spelling is wrong I'm sure

When I had a problem with a locust tree a few years back, I was able to go to our county government, which had a small staff of trained agricultural experts.
For a very nominal fee ($1, if I remember correctly) they would take a look at a plant sample and make a recommendation/diagnosis.
Maybe your county has something similar...

That's Lecanium Scale. Imidicloprid will help if timed properly. Also 3% oil sprayed in spring and another application of a synthetic pyrethroid when the crawlers hatch. Check timing with your extension service.

Thanks for the help. I have applied Malathian to it once, two weeks ago. Do I need to wait to use the recommended treatment?

Read the labels of the products.
That's where precautions and recommendations are listed.
I don't believe that the scale is causing your trees to die as you say...
Appearance of scale is often one sign of a stressed or weakened tree. The recommended treatments should take care of the scale, but you need to take a closer look at the underlying cause of the tree's natural immune system failure.
Buried root flare? over/under watered? root system tampered-with? recent nearby construction? recent climate extremes? etc.
All trees benefit from broad expanses of mulch and mineral powder supplements like lava sand.

PS - If no one at a local nursery could ID that as some kind of scale - then you need to give someone in the next town your gardening business....pretty basic for someone in the nursery biz....
