We use simizine for our Fall apps. & switch over to barricade for our late winter & early spring apps. I have tried many different combos of pre-m's in the spring & for our clay soil in OKC the 2 apps. of barricade seem to give the best crabgrass control. I see you're here in OKC, if you have any questions about vendors or anything else PM me.
