Great for Chamberbitter
By Bruce on 09/02/2019
Works great to kill and control chamberbitter. Although chamberbitter is not listed this product contains Isoxaben which is the herbicide that kills chamberbitter. If you follow the directions this product will also act as a pre emergent for chamberbitter.

By Gordon on 02/27/2016
I ordered this product in hope of preventing poa anua from emerging. I Used a liquid dispenser and dit on aor about Jan 5, 2016. It had not affect on preventing the poa anua from popping up. It looks like this weed is growing as it's always done through out the last 40 years. On the internet I was found poa anua listed on your weed list. But it isn't listed on the brochure that came on the product.

Bayer Season Long Concentrate
By Steven on 04/24/2013
The product seems to work but too early to tell for the whole season. Called Bayer and asked about about setting for a hose attached sprayer 1.5- 1.6 oz.setting. Use disposal gloves,long shelves and apply on a non wind day. Rain will work the chemical in the ground.Very simple to apply using this method.

Bayer Advanced Season Long Weed Control For Lawns Concentrate does have a pre-emergent in it and will control weeds before they germinate, however it does not control or prevent crabgrass. We would recommend one of our other pre emergent items like Hi Yield with Dimension or Prodiamine 65 for a pre emergent to prevent crabgrass in the spring.
