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.
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.
What will happen if I lay down the Image without MSMA? Someone else
posted that it shouldn't be used with St. Augustine.
Also, can you tell me if I can lay down Image, if I have recently laid
down Bonus S?
I haven't had a problem just using Image by itself. It takes several weeks
to kill sedges so some people think it doesn't work well, but you just have
to be patient with it. I do prefer to use it via a hose-end sprayer. I
noticed this year they have started selling it with the hose-end sprayer
