After spraying Tenacity Herbicide, when the weeds turn white, do you pull them or just reseed?

I was told I had nimblewill in my yard. It was a large portion with green blades and brown plus some other weeds. I purchased tenacity from you and applied it. The areas that were brown and green haven't turned white but the are scattered portions of other weeds that have. Does that mean anything? Also, am I supposed to pull them after they turn white and reseed?


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.
