COLUMBIA, Mo. – University of Missouri Extension weed scientist Kevin Bradley lists two weeds to watch in 2024. Knotroot foxtail, like yellow foxtail, has a short, hair-like ligule and a typical foxtail-like seedhead. Unlike yellow foxtail, however, this species has short, knotty rhizomes. The invasive perennial is also known as bristle grass.

Glufosinate-resistant Palmer amaranth found in Missouri Bootheel
PORTAGEVILLE, Mo. – University of Missouri Extension researchers have confirmed the first case of glufosinate-resistant Palmer amaranth in Missouri’s Bootheel region.Palmer amaranth has been MU Extension weed scientist Kevin Bradley’s No. 1 weed to watch in the rest of the state for years.Palmer amaranth spreads and adapts quickly to herbicides. When it goes to seed, the weed is a superstar, producing as many as 1 million seeds per…
Benefit of killing annual weeds in winter wheat depends on weed, yield loss
COLUMBIA, Mo. – Killing common annual weeds in winter wheat may or may not be a good financial decision, especially when input costs are high, says University of Missouri Extension weed scientist Kevin Bradley.Winter wheat is one of the most competitive crops planted, Bradley says.Bradley offers these guidelines based on research from MU and other reputable sources.Common chickweed
Plan to kill toxic perilla mint this spring or summer
MOUNT VERNON, Mo. – University of Missouri Extension livestock specialist Eldon Cole said he received a report recently of cows in southwestern Missouri being killed by perilla mint, a toxic plant. Cole urges producers to plan to destroy the annual plant in pastures next spring or summer. Broadleaf pasture herbicides, applied April through June before seed set, provide control when applied at the correct rate, he says.

COLUMBIA, Mo. – Cereal rye as a cover crop may reduce waterhemp populations without yield loss in soybean, according to a three-year study at the University of Missouri.
Weed electrocution research sparks interest as herbicide resistance impedes current methods
COLUMBIA, Mo. – Move over, herbicides. There’s a new sheriff in town. And he’s toting some powerful guns loaded with electricity to kill weeds. This shocking new method of weed control was demonstrated at the 2021 Pest Management Field Day at the University of Missouri Bradford Research Center in Columbia.
Mizzou Weed Science shares Seed Terminator research
COLUMBIA, Mo. – In the 1984 film “The Terminator,” a robotic assassin played by Arnold Schwarzenegger warns, “I’ll be back.” If waterhemp could talk, it might say the same thing. Waterhemp can’t be bargained with. It can’t be reasoned with. The prolific producer of seeds is the state’s No. 1 weed, robbing Missouri agriculture of millions of dollars each year.

Waterhemp is one of 14 herbicide-resistant weed species in Missouri. It is a prolific producer of seeds, and Bradley considers it Missouri’s…
Off-target movement of dicamba in Missouri: Where do we go from here?
The situation. In 2017, there have been numerous instances of off-target movement of dicamba throughout the state of Missouri and beyond. While the majority of the injury on a per land unit area has definitely occurred in the boot heel of Missouri, there are many problems with off-target movement of dicamba in the rest of the state.
Survey of Missouri Pesticide Applicator Practices, Knowledge, and Perceptions
The introduction of soybean and cotton traits with resistance to synthetic auxin herbicides has led to an increase in concern over the off-target movement of dicamba and 2,4-D. A direct-mail survey was sent to Missouri pesticide applicators in January of 2016 to understand current herbicide application practices and applicator knowledge and awareness of the new synthetic auxin technologies.
Weed management issues related to the flooding and wet conditions in Missouri
Obviously, our season so far has been one for the books. Our state climatologist Pat Guinan tells us that last month was the wettest May on record ever! We’ve been fielding a number of questions over the past several weeks related to the wet weather and how this affects our herbicides and weed management practices. In this article, we present a few brief thoughts that provide some answers to the most common questions we’ve been getting.
New tests by MU scientists will kill weed seeds before they become weeds
COLUMBIA, Mo. - Kill seeds before they become hard-to-kill weeds. That plan will be studied by Kevin Bradley with help from Missouri farmers.The University of Missouri Extension weed specialist plans research on crushing seeds before they hit the ground. That stops weeds competing with crops next season. Over time, that depletes soil seed banks.

As we move into that part of the season where post-emergence herbicide applications are commonly made in soybean, it's important to remember the effects that off-target movement of herbicides can have on others around you. And this year, for the first time ever, we will be able to legally apply dicamba (in the form of Xtendimax, Engenia, or Fexapan) to Xtend-traited soybean.
Palmer amaranth is still on the move in Missouri
Palmer amaranth is a member of the pigweed family that is native to the southwest United States, but has slowly migrated into the Midwestern U.S. over the past decade or so. In the bootheel of Missouri, like western Tennessee, Arkansas, and a host of other southern states, Palmer amaranth has been the predominant pigweed species for several decades.
Cleanout and upkeep of the sprayer: Don't get complacent
The availability of dicamba-tolerant soybean this season increases the need for emphasis on proper maintenance and thorough cleanout of the sprayer system between applications; especially POST applications. The likely introduction of additional herbicide-tolerant traits in the future indicates that sprayer maintenance and cleanout will continue to be an essential focal point to avoid tank contamination and injury to subsequently…
