Certainty regimen seems to have prevented Yellow Nutsedge

Post by Green » July 23rd, 2021, 1:16 am

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.
