Q4 Plus Turf Herbicide
- Product Review (submitted on July 13, 2014):
- I bought this Q4 Plus to kill a Virginia Buttonweed weed which had come back in my grass. This weed is very difficult to kill, I used Roundup on it last season, killing the weed and the grass. I re-seeded the yard, and this year the Buttonweed came back. After applying Q4 Plus for the first time, initially I did not see results, but a week later the Buttonweed was dying. Another application and another week did the job. The fescue grass turned brown in the area of application, but it did not die completely. Overall, this product did what I bought it to do, don't expect the weeds to die as rapidly as they do when you use Roundup, just give it a little time to work. The technical service at Do It Yourself Pest Control was excellent when I called to discuss the product with them.
