University of Illinois weed scientists have confirmed resistance to the herbicide dicamba in a Champaign County waterhemp population.
Scientists have published the most comprehensive genome information for three weed species, marking a new era of scientific discovery toward solutions.
While there are dozens of common weeds that threaten yield each season, many Midwest farmers who grow corn or soybeans are facing off with waterhemp now. “New cases of resistant waterhemp are daunting to those of us in the ag industry because it threatens the already-delicate ROI ratio,” says Dave Roome, customer technical specialist, Corteva […]
A recent update to the Liberty label will allow growers to tackle weeds like Palmer amaranth and waterhemp at a higher rate. The ability to apply the herbicide to LibertyLink crops at a higher rate in 2018 will also help improve control of other driver weeds like kochia, ragweed, and marestail. “As weeds like Palmer […]
Whether the concern this year was Palmer amaranth, waterhemp, or giant ragweed, farmers can implement helpful practices to control herbicide-resistant weeds in the future. Mark Bernards, associate professor of agronomy at Western Illinois University says the two best ways to delay, or prevent, herbicide resistance is to apply herbicide mixtures that have active ingredients effective […]
Palmer pigweed and waterhemp went viral across the Midwest this 2017 growing season so it was no surprise that weed control was one of the most popular questions Syngenta fielded this year at the Farm Progress Show. “You can drive down the road here in central Illinois and pick out the soybean fields where you […]
Resistant to five modes of action, can travel a half mile or further under windy conditions, and remain viable in the soil for several years — there is no doubt about it, waterhemp is a beast. “Whether they are from Missouri, Illinois, or Minnesota, it sounds like they all have a very similar problem with […]
Palmer amaranth, residual control, and soybean waterhemp seemed to be the most common questions among soybean growers this season and while every field potentially has unique weed management challenges depending on weather, soil type, and weed control methods, Dow AgroSciences field scientist Dave Ruen has some tips. “At this point in the season, farmers can […]
