Can you grow vegetables into soil the following year?
RoundUp Pro Max contains glyphosate, which is absorbed systemically into the treated plants only. It does not move through the soil to other plants, and it is not absorbed from the roots into neighboring plants. Since this product is not labeled expressly for us around edible plantings, it should be safe to plant vegetables after a year. You could also use Avenger Herbicide and replant as soon as 2 weeks after application. The delay is just to be sure the target plants have had time to be killed before you till any roots that may still be viable.
