Waldron, MI | What all do you use to control giant ragweeds in corn and soys? Many appear to be somewhat resistant to glyphos. Our corn program seems to hold them in check for a while but we have had to do some rescues with glyphos. We use Canopy in the fall on ground going to soys the followng year, followed with a mid summer glyphos application but, obviously, by mid summer, the rags are taking off pretty good. So far we've been able to get them but I'd like to knock them out more aggressively. | |
