What is this getting after my bur oak saplings?

[whitenack]

Can someone identify the pest and recommend a treatment? These are bur oak saplings planted from acorn in central Ky, zone 6.

I don't know what they are but sevin dust or spray will probably take care of them.

Maybe some jumping oak galls
Probably some Tubakia and oak leaf blister

All inconsequential...but that second pic doesn't look good. How long have they looked like that?

 

[whitenack]

They start out looking like the first pic and then after about a month they look like the second pic. I have another sapling about 20 feet from this one and all of this year's growth is completely destroyed.

It may be B-O-B or Bur Oak Blight. Go here:

Putting my money on B-O-B

Thanks. Definitely not Round Up over-spray. I'll look into BOB.

It may help if you can flip the leaf over and take a few pics of the underside. It may be an insect with piercing and sucking mouth parts similar to Oak phylloxera.
My first thought was fungal and possibly galls as ATH posted however I'm not sure.

Good pics, don't see any insects under the leaves. I concur with ATH on the jumping oak gall.
