The Atrazine in the Bonus S isn't effective on sedges at all. Roundup
probably will take the top off of it, but the root will come right back.
Image is good but you'll probably have to use it in combination with 529
MSMA. The other option is a product called Manage that is labeled for purple
and yellow netsedge. Might work on globe sedge too.

Okay, I'm trying get better at maintaining my own lawn. I have this
weed or crab grass that I have looked up on the Internet and believe
to be Globe Sedge. I can spray this stuff with Round Up and it still
won't die. I've used Scott's Bonus S -- nothing.

Any suggestions?

Use a product called Image. It's very effective against sedges.
