i have had the same question. I split a two acre white/ladino clover plot with a 40ft strip this late summer. I am prepping it for CIR switch. I have sprayed round up three times since mid july and have a great prep plot for CIR this spring. We'll see how it works. My problem is going to be spraying chems on the switch and the clover and not killing the other. I'll let you know how it works. Funny thing, deer are lazy I think we all know that. Since I started killing the strip through my clover, the deer use the strip exclusively for a travel corridor cuz there is nothing in there way!! It's ridiculous, if I could hunt in the late summer there would be no deer left cuz they all use the bare strip for travel!! Anyway, I'll let you know what it looks like, but it'll be a year from now.
