What troublesome invasive weed do you have in your area?

You are so right. I look into my backyard at the forest (NJ) and I see so many bare trees (ash) that are dead from the emerald ash borer. My forester now tells me that the latest issue is a fungus that is killing beech trees. Also very sad as the beech trees, one of my favorites.
I've received a lot of recommendations to put down pre-emergent in November and again in February to prevent springtime germination, in April.
There are two pre-emergent herbicide chemicals that are the most effective in Texas according to Texas A&M, herbicides that contain Oryzalin or Pendimethalin. These are generally professional products that are not available in stores like Home Depot or Lowes but are available to order on-line, I get mine from Amazon. They need to be applied at least twice a season in Texas, the first in mid February and the second in late September. Some experts say that it should also be applied in June, but I have had good control of sandburs with just two applications.

Plaintain?
There are some online sellers that I shop that some times have better priced on those products and I find that the lower application don't works very good. Pendimethalin is approved for ag use.

Tricopyr herbicide was "supposed" to be good for killing clover,but not very impressed with it.

My lawn is pretty much completely crabgrass. Can't help it in a townhouse where the neighbors lawns are also crabgrass.
Nothing is more invasive than this creature
Very similar situation with Quack grass up here in the rural areas.
Here is an example of the Quack grass issue. It dominates In the rural areas and only Round Up can get rid of it. It competes with finer grasses and grows quicker. If left too long it gets several inches taller than the finer grass. Here’s a pick from a neighbour’s yard. Ironically, in drought stricken yards that are not irrigated it will remain greener while the good grass turns yellow. Most folks just accept it and mow more often.

Johnson grass!

The first two are similar in appearance. Nasty. Poisonous. Invaders.

No so much a weed, but my urban property had two "trees of heaven" on it. Hundreds pop up in spring/summer. We cut/pull them as quick as we can. Next week they are back. If left too long it's a full on tree to deal with.
The Nimblewill is getting out of hand and as I am told it only gets worse. The last two summers have been quite dry so it suppresses the good grass and the Nimblewill thrives. Bit the bullet and ordered 32oz of Mesotrione aka Tenacity. Still will have to deal with what sprouts from seed and I have about 2 acers to hand treat. 
But it is literally taking over out in the sun. The mower spreads it. I can see in my backyard where I use to wash out the deck after use it has spread there too.
Although invasive maybe a bit untrue it is out of it's habitat of low lying flood plain.
