Thanks for the replys fellas. Here a few photos for reference. These matted down areas are almost 100% Foxtail. I have some Kanlow seed already that I would still like to broadcast in. I guess for me the issue with timing any spraying in the Spring if I seed again is having established switch green up before the new seed germinates. I thought I read that Quincloric would damage new plantings. I might have remembered that wrong. I am probably overthinking this way too much. Thanks again for the advice.
