For those of you who have dealt with this stuff, How did you get rid of it? I had some come in last fall, absolutely no clue where it came from as I had never seen nor had it before. It produces tons of seeds so I figure this spring it's popping up all over again. Should I put down a pre emerge now to stop the seeds from coming up ? Or will that keep my buck wheat and sunflower seeds from coming up when I plant in May? Should I wait until green up and spray the whole field with Gly and 2 4D? Just looking for advice. Thank you!
