In no-till corn and soybean fields, it is essential to apply herbicides with foliar activity before crop emergence to control existing weeds. Depending upon the herbicide approach used in the field for that year, herbicides used to control weeds at planting may include glyphosate or paraquat. Use of herbicide combinations in burndown treatments is justified in most no-till fields, due to the variety of winter annual weeds present. Consider fall herbicide treatments in fields that are heavily infested with such species as chickweed, marestail, dandelion, wild carrot, and poison hemlock.
