Product Q&A

Answer:

You should be able to safely mix the Quinclorac 75 DF with the Speedzone to get a wider range of weed and weedy grass control with no issues. As with any chemical mixture, be sure to do a tank mix test first to make sure no clumping or mixing issues occur and spot test a small area to be sure no undesirable effects occur from the mixture and use. Always follow the most restrictive label of the two for use. Per the Quinclorac 75 DF product label, only use on fine fescue if its incorporated into a fescue blend as some turf damage or discoloring could occur if its a fine fescue lawn only.
