Tom said, "Smart weed, knotweed etc." Smartweed huh? What a pest for me, I have an 80 acre field of grass seed with smartweed aka ladysthumb growing in it that I can't eradicate. It comes out of the lake with the flood waters every winter. Tough weed to control, grows easy on land anyway. How much do you want? I can send out truckloads of the stuff. Matt
