Hand pulling POA..
Just thought I'd share my experience this morning. I noticed two decent size Poa patches; that annoying light green standing out in the KBG, but no seedheads.

POA really showing up now, pulling by hand
I fertilized a few weeks back and the grass is darkening up a bit. The bad thing is that the POA shows up more now than ever. I've been pulling the POA by hand here and there and I'm just going to keep pulling it and hope for the KBG to fill in the bare spots. I hate the brown spots from RU, bare spots are not seen as easily.

I didn't know Barricade is more expensive then Prograss, which I already consider out of the hands of most homeowners. Sounds like you are in the biz which is always a good perpective here.
Management
Overview
- Poa annua grass, also known as annual bluegrass, is a annual weed that is commonly found in lawns, but can be found in gardens as well. It is rather difficult to control because the plant will produce several hundred seeds in one season, and the seeds can lay dormant for several years before sprouting.
Characteristics
- The identifying characteristic of poa annua grass is the tall tasseled seed stalk that will typically stand up above the rest of the lawn and becomes visible in late spring or early summer. But, while this seed stalk can be tall, if it is cut short, it can still produce seeds.
Effects
- Poa annua grass is typically a problem in the lawn because it dies back in hot weather, which can make unsightly brown spots in the lawn during the height of summer. It also thrives during cool weather, when most lawn grasses are dying back, which means that it invades the lawn at these susceptible times.
Treatment
- There are some herbicides that will selectively kill poa annua in lawns, but they can only be applied by certified professionals. Non-selective herbicides or boiling water will also kill poa annua, but these methods will also kill any other plants that they come in contact with, so these methods should only be used in areas where you wish to kill p...
Safety
- Note: Chemical control should only be used as a last resort, as organic approaches are more environmentally friendly.
