Herbicide options for killing failed corn stands

I have already received a few calls about herbicide options for killing out poor stands of Roundup Ready and/or stacked Roundup Ready/Liberty Link corn, and I expect there will be more whenever things dry out. We conducted a few trials on this several years ago, and Dr. Larry Steckel has also published some data in the weed science literature from two years of research he conducted in Tennessee.

A final report on dicamba-injured soybean acres

Throughout the summer we have attempted to provide updates as to the extent of dicamba-injured soybean throughout the United States, either in the form of official dicamba-related cases that are currently under investigation by the state Departments of Agriculture, or as estimates of injured acreage from university extension weed scientists (see Ag Industry, Do we have a problem yet? and Update on Dicamba-related Injury Investigations…

Ag industry, do we have a problem yet?

It's funny how we can be living through a situation or watch something unfold in front of our very eyes and one person can view it one way and another can see it totally different. If you think about it, this happens all the time at sporting events. Not too long ago I was watching a Cardinals game with some Cubs fans and all of a sudden they all started yelling that our player was out when I could clearly see that he was in fact, safe…

What have we learned from four years of studying temperature inversions?

We are beginning our fifth year of monitoring inversions in Missouri. In 2017 we started expanding our inversion monitoring network and also began studying how inversions affect dicamba applications thanks to partnerships with colleagues at other states and funding from the United Soybean Board, Missouri Soybean Merchandising Council, and the U.S. Dept. of Agriculture.

July 15 Dicamba injury update: Different year, same questions

As explained in previous articles from this season (Dicamba Injury Mostly Confined to Specialty Crops, Ornamentals and Trees so Far, Dicamba Injured Crops and Plants Becoming more Evident: June 15th Update), I have attempted to provide updates as to the extent of dicamba injury throughout the United States, either in the form of official dicamba-related cases that are currently under investigation by the state Departments of…

Five things we’ve learned about dicamba

As we prepare for another year with the Xtend soybean and cotton system, we thought it would help to briefly summarize some of the most important things we’ve learned about dicamba as a result of the research our outstanding graduate students have conducted over the past several seasons.

MU researcher finds pigweed in birdseed and pollinator mixes

COLUMBIA, Mo. – University of Missouri researchers, under the direction of MU Extension weed scientist Kevin Bradley, are finding that pigweed seed is popping up in birdseed in alarming numbers.“It’s pretty shocking,” graduate student Eric Oseland told those attending the annual Integrated Pest Management field day recently.
