Jim Legvold’s weed-management story began when this Vincent, Iowa, farmer planned out his program, embodying a new approach. But the plot thickened after an extremely wet spring and cool summer thwarted his best-laid plans. Weather extremes, weed adaptability and low crop prices challenged his long-term plan of corn-soybean herbicides, residual herbicides and rotated modes of action....More
Weed resistance happens when a herbicide program relies on only one mode of action. This places extreme selection pressure on weed populations, which means a number of resistant weeds can survive the herbicide application, producing thousands of resistant weeds.
September soybean fields in Nebraska, Iowa and Minnesota displayed large numbers of escaped waterhemp. Perhaps this was the case in other states, too. While your combine journey across all your acres is fresh in your mind (and your partners’ minds), take time to evaluate your weed control program to enhance future effectiveness....More
Herbicides applied in the fall often can provide improved control of many winter annual weeds, including marestail, compared with similar applications made in the spring, says Aaron Hager, a University of Illinois weed scientist....More
