Will Speed Zone kill black medic and it's mature seeds ready to drop and reproduce?

The black medic has almost mature seeds , will this product kill the seeds before they can start to germinate


SpeedZone Lawn Weed Killer Concentrate is labeled and will treat for and suppress black medic, but not kill the seedlings that are present. Please review the product label to make sure your turf grass is tolerant of this product. We also recommend that you consult with your local cooperative extension office Master Gardener on using other active ingredients in your specific lawn type.
