Roundup, of course.

Hi Joe.

My friend has tried several applications of Roundup.
These weeds laugh it off.

Thanks, though.

He's doing it wrong. For starters, there are a lot of variations on
Round Up. Most people buy the cheaper versions that is 'pre-watered
down". Buy the full strength stuff, and mix it yourself to whatever
styrength is needed for each individual situation. The stuff that
comes in a spray bottle won't kill anything that is much tougher than
lawn grass.

Mix 10-12 oz of full strength Round Up to a gallon of water and you
can kill astroturf and fake palm trees.
