I have had a huge problem with spurge the last 2 years. When researching herbicides and pre-emergents, I found that many herbicides and pre-emergents don't work very well on spurge. I used this last year, and I think it really cut down on my spurge infestation this year.
Excellent Crabgrass preemergent , easy to use
Anderson's Dimension is the best pre-emergent out there. I've worked on numerous golf courses and they've used the same stuff. My yard looks great with no crabgrass or annoying broadleaf weeds. AM LEO sells at a great bargain too!
