Palmer amaranth, commonly known as pigweed, has been a longtime foe of Arkansas soybean farmers. Jason Norsworthy, weed scientist for the University of Arkansas System Division of Agriculture, said it is the No. 1 weed affecting Arkansas soybean production. However,...

Palmer amaranth is one of the most economically-damaging and difficult-to-control broadleaf weeds across the United States. Previously, Palmer amaranth in Kansas has developed resistance to group 2 (ALS), 5 (atrazine), 9 (glyphosate) and 27 (HPPD – mesotrione, Huskie, Laudis,...

Rotate control methods and crops to slow development of PPO resistance in Palmer amaranth. By Vicky Boyd Editor Although two new herbicide-tolerant crop technologies have recently hit the market and a few others are in the pipeline, weed experts say growers should still practice integrated weed management to slow...

As you sit in the combine, which provides a bird's-eye view of the field below, take time now to scout for potential 2017 weed problems. As you see problem spots that survived herbicide treatments, University of Missouri weed scientist Kevin...

You undoubtedly have seen headlines, such as “10 worst cities in which to live” or “Top 10 worst cities for car theft,” in the popular press or online. The Weed Science Society of America has its own survey in...

Don’t wait — take pre-emptive steps now to slow PPO herbicide resistance from developing in Palmer pigweed. By Vicky Boyd, Editor Bob Scott, a University of Arkansas Extension weed scientist, is on a crusade before planting season starts to educate producers about herbicide...

The time of day when Liberty herbicide is applied can affect its effectiveness on Palmer amaranth, according to University of Tennessee studies. But researchers also have found that time of day can affect the efficacy of PPO herbicides, such as...

Draft a weed-control plan before planting, don’t skimp on preplant treatments and rotate modes of action. Soybeans are expected to see another low point in commodity prices this year, but that won’t change the pre-planting habits of Mid-South growers, such...
