I did it once. I sprayed, got a good kill. Then disced. Waited two weeks then sprayed, broadcast seed then cultipacked. I checked them roughly 2 weeks later and they looked great. Checked again roughly a month after that and realized I lost. I thought I’d be GTG with the minimal soil disturbance (cultipacking) after the last spray. But the “weeds” grow like crazy during that time of year too. That plot became a PPT plot later in the year, there were sugar beets hidden in the mess, but they were thin and small (golf ball to baseball size).
