Another POa Annua Question. Post Emergence after seedhead?

Post by Belgianbillie » Fri May 17, 2019 4:25 pm

I talked to the guys at site-one and they told me that prograss and poa constrictor are basically growth regulators and actually dont impact post emergence poa annua if it already has seeds.

What do you guys suggest?

I would suggest not listening to the site one guys or us. Read the label for ethofumesate and it will tell you if it treats POA a or not. If your post has seed, they are likely viable. So you need a 2 step approach, 1) ensure your POA a dies and 2) ensure those seeds don't become new POA a.

For step one there are multiple methods. For step two, you need a prem at the end of summer.

i just purchased some ethofumesate and treated two 2'x2' sections in my yard. both spots had seed heads present and i went with label rate (.5oz/k) of the product. hopefully in a few days (???) ill be able to let you know how effective the product is vs poa A that has went to seed.
