I was wondering whether a 2-application Certainty regimen for Poa triv was going to prevent/kill Yellow Nutsedge since it's labeled to do so at higher rates.
I am now 6 weeks past the second app of a 2-app program. There is no Uellow Nutsedge. The area historically has had it, and there is currently Yellow Nutsedge on both sides of the treatment area.
I think we can conclude it prevented it.
That said, protection will likely wear off soon if I had to guess.
Certainty regimen seems to have prevented Yellow Nutsedge
