That looks like poverty sumpweed, Iva axillaris. It is a tough weed. You can use glyphosate. There are several broadleaf herbicides listed for its control, but I would be very careful around the vines. We had a couple cases of vineyard damage from herbicide last year.  https://www.ag.ndsu.edu/weeds/weed-control-guides/USDA-Final.PDF  Always read and follow the label.
