Thanks for the reply guys, I will have to spot spray with these as all of them also kill clover and chicory that I have planted. I sprayed roundup and a product called Crossbow, let set 3 weeks before tilling up. i went out last weekend and spot sprayed with a 50/50 mixture of crossbow and water, went out Friday Night and looked like I sprayed fertilizer instead of herbicide.
I have been fighting this for a long time, and don't seem to gain on them at all. Thanks again.
