Herbicide resistant traits available in soybean continue to increase. It does not seem that long ago that there was either Roundup Ready or conventional soybean. There are no less than eight different soybean herbicide resistant traits available today with the most recent being XtendFlex soybean. Continue reading
As we approach the fly-free date for sowing winter wheat, we need a plan to control our most common weedy pests in this crop. The two most common weeds in our wheat every year are poa and ryegrass. The fall is the best time to control these two weeds in wheat. Continue reading
Some have been concerned about losing dicamba due to court or EPA rulings. Everyone should be more concerned about losing dicamba and 2,4-D to Charles Darwin’s theory. Weeds developing herbicide resistance has caused the loss of many more herbicides than anything a court or the EPA has ever done. It’s not even a close race.
This is particularly true for Palmer amaranth. The newest development is that Palmer amaranth has evolved dicamba resistance here in Tennessee. We are in the beginning stages of Palmer amaranth, yet again, becoming a major problem due to the loss of a herbicides’ utility on that weed. Continue reading
If you missed the Corn Inservice webinar, we’ve broken out the five presentations, which are available to view now at the UT Crops YouTube channel.
Has Palmer amaranth evolved dicamba resistance in Tennessee? Results from some of the greenhouse experiments this winter and spring as well as in field research this growing season would suggest that our state now has dicamba-resistant (DR) Palmer amaranth. These DR populations are established in Crockett, Gibson, Madison, Shelby, and Warren counties and likely several others. Continue reading

Below is a link to the recorded presentation of the 2020 UT Soybean Scout School that was presented today via Zoom. Set aside a little time if you intend to watch. Also keep in mind that much of the same information is available on our other internet resources including http://utcrops.com/soybean/VSSchool.htm and https://guide.utcrops.com/soybean/.
Calls continue from some folks frustrated with goosegrass, junglerice and Palmer amaranth escapes after a dicamba + glyphosate application. A large reason for the frustration is the follow-up applications have often provided less control than hoped. Timing is the cause for some of these poor weed control issues. Herbicide resistance is another cause. Continue reading
