Weed growth will resume quickly when conditions get warm and the rains stop. Then it will be at least a day or two after that before fields are dry enough to drive on and before crop stressed by frost or excess moisture recover enough to allow good tolerance of herbicide. That means bigger weeds to content with. In that case, growers will want to use higher spray rates — but stay within label limits — to ensure optimal control of these larger weeds.
When it comes to weed control, don’t delay when the opportunity presents itself. “Moisture tends to bring more moisture. That means spray windows this year are going to be smaller,” says Jim Bessel, CCC senior agronomy specialist.
