Pre-emergent - before or after mowing when coming out of dormancy

Hello all!

I have tifway bermuda and I think I might be a little late applying my pre-emergent. I have a few grassy weeds popping up here and there and the bradford pears are starting to bloom in my area. I looked up the soil temp for my area and it says between 55-60.

My question is, I noticed that digging down through the grass (I left it long to help protect it over the winter), the bermuda is starting to come out of dormancy. I know according to the bermuda bible, that I should scalp the yard at this time and discard the clippings. However, it also says to apply the pre-emergent before I mow for the first time.

So my questions are:

1) Do I go ahead and apply the pre-emergent?
2) If so, how long should I wait before the initial mow?

If the answer is now, I guess I should go ahead and mow as soon as possible and then apply?

Thanks for all the help!
