Anybody know what to use to safely kill nut sedge in a zoysia lawn?
Thanks,

Scroll down for the herbicide chart here:

And here (http://www.walterreeves.com/lawns/article.phtml?cat=29&id=153), further detail is given:

"Nutsedge is much tougher to control than crabgrass. Fortunately, you can mix two herbicides and get good control of nutsedge and excellent control of crabgrass. Use imazaquin (Image) and MSMA (Crab-E-Rad) in your sprayer. You'll need three applications spaced ten days apart. Some zoysia discoloration will occur, so water the lawn thoroughly two days after application to keep the grass healthy"
