Hey guys I have a commercial account with a lot of wripwrap ditch around the property. I'm having no luck controlling horseweed with glyphosate. Anyone know of something that will take this stuff down. Ive mixed it very strong, tried spreader sticker, and it just yellows the tops of the plants for a week or so then greens back up. I read there were reports of gly resistance with this weed, but the University of TN turf website doesn't have any alternatives to try. I am having to spray every couple weeks to control weeds, a pre-m would help too, mostly goosegrass, crabgrass, chickweed, and a little purslane is what I'm trying to get. Thanks in advance.
