Hopefully I can post these pics OK. I believe the weed is Orchard Grass or Barnyard Grass. There is no pre emergant that has been effective, and no selective post emergant. I only see it on about 7 or 8 lawns so far. Most customers think it is crabgrass so I get the blame. The picture was taken on a property that was sprayed twice with roundup prior to renovation. Anyone else dealing with this and what is your course of action. It is by far the worst problem I have because I don't know any other solution other than roundup and that is no long term solution. It looks very bad on the lawns that are infested.
