A study tested different ways to control weeds in winter maize fields. They tried using herbicides like atrazine and pendimethalin, along with hand-weeding and 2, 4-D spray. The best method was using atrazine and pendimethalin together, followed by hand-weeding or 2, 4-D spray. These methods reduced weed growth by a lot and increased maize yield. The most effective approach was atrazine + pendimethalin + 2, 4-D, which gave the highest profits and benefits. So, using a mix of herbicides and hand-weeding can help farmers grow more maize in winter.
