After learning we have massive amounts of nimblewill grass, our lawn was treated with Tenacity - 2 applications. At this time, basically the entire yard has turned white. I have been raking trying to clean up the nimblewill but it is just so much. Should I continue to do that (considering hiring a company), and our lawn will end up dirt prior to seeding, or should I stop and just add see to the existing white lawn? I want to make sure this stuff is gone for sure!
After spraying with Tenacity Herbicide, the foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll), and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control. We would not recommend pulling up any weeds because the product will not get into the root system, and the weeds may come back at that point. It is usually best to remove any excess dead plant matter before you over seed the lawn. Tenacity will not interfere with seed germination of turf grasses listed as tolerant on the product label.
