Scientists have published the most comprehensive genome information for three weed species, marking a new era of scientific discovery toward solutions.
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 […]
Minnesota landowners are being told they need to be cautious when buying and planting seed, especially for conservation plantings. Recently, the Minnesota Department of Agriculture has encountered several issues with seed sold in the state. In 2016 and 2017, the highly invasive weed Palmer amaranth was introduced through conservation seed mixes. The department found seed […]
Glyphosate-resistant Palmer amaranth, one of the most threatening weeds in Southern corn and soybean fields, is spreading into the Midwest, warns Syngenta. Palmer amaranth, a member of the amaranthus (pigweed) family, has a complex lifecycle. The combination of its ability to develop resistance and its extended emergence period makes it especially difficult to control. Known […]
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 […]
Growers should be watching out for Palmer Amaranth, a weed that has been rapidly spreading north in the U.S. and is likely to be Glyphosate resistant. “Now is the time to scout for Palmer Amaranth,” said Paul O. Johnson, SDSU Extension Weed Science Coordinator. “In most cases, Palmer Amaranth should be about fully grown which […]
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 […]
