Ok, couldn't figure out how to get pics posted but sprayed entire field today. ..now what
Now you wait until toward the end of Sept when the weather cools off a little and some good rain is forecasted. You can check it in a couple of weeks and see if you missed any spots spraying.
BTW...I would recommend that you use a lot of cereal rye in your mix. It'll stand the best chance of having success in your situation if everything isn't perfect.
