looking at the label for Celsius WB it says NOT to use it on cool season grasses... But just want clarification that it says not to use it because it will kill it. Which is what I want.

Best way to kill remaining cool season mixed into my warm season?
Was hoping for some suggestions here. I Seeded zoysia and honestly just didn't really know what I was doing and decided to also seed ryegrass in the bare spots as getting zoysia to germinate is really tough. The thought process here was to give the zoysia something to take over. Well, it's done a pretty good job taking over the rye, but there is still some remaining and it's naturally a lot darker green than the rest of my lawn. Now that my zoysia is 90% established, what would be a good way to kill the remaining PRG without harming the zoysia?
I also overseeded my front yard of 100% PRG but got frustrated by how fragile and susceptible to disease PRG is so I would like to do the same there although the lawn is currently 80% PRG with zoysia seedlings germinating throughout.

If it's safe on zoysia then go for it.
You are correct - it says not to use it on cool season grasses because it will kill them. :thumbup:vanawesome said:looking at the label for Celsius WB it says NOT to use it on cool season grasses...

I wouldn't spray while the zoysia seedlings are still in a fragile state. Read the Celsius label for any other restrictions that may apply to your situation, but with a quick scan I found this:
Seeded Zoysiagrass: This product may be applied to zoysiagrass up to 90 days prior to seeding without a significant
reduction in zoysiagrass stand. For newly established stands of zoysiagrass, do not apply this product for at least 3
weeks after germination as injury may result.
Thanks ware. I guess the follow up question would be.... Do you recommend doing it this way? Or would you leave well enough alone and let he Zoysia naturally finish taking over the yard over the next season or two?
It wouldn't bother me at all to knock out the PRG with a chemical at the appropriate time. That's going to be your shortest path to a zoysia lawn. I am overseeding my back yard with PRG this fall, and will use a chemical to kill it off in the spring. Just follow the label with regard to rates, annual max, temp restrictions, etc. and it should be fine.vanawesome said:Thanks ware. I guess the follow up question would be....

Just FYI, Certainty will kill PRG also!
Ordered certainty because it was about 40 bucks less than celcius. I will apply this weekend and update with results.
Zoysia is a slow filler slash spreading grass. It will though. Give it some time. Keep the water on it and it will respond.
