Since we could not gather today for the annual Weed Tour, Dr. Larry Steckel and Clay Perkins have developed a few short videos highlighting weed management research.

Plan “B” For Palmer Escapes After Dicamba or 2,4-D

Jun
2020
Some reports have come from folks concerned by the lack of Palmer amaranth response to applications of dicamba plus glyphosate applied in the last 10 days. I expect to get more of these calls as I have seen similar results in our research this spring. Continue reading

UT Weed Tour Cancelled

2020
Dear Colleagues
The University of Tennessee Weed Tour has been cancelled. Due to the covid-19 virus no large groups are allowed to visit a University research station. Since we cannot have an in-person tour, we plan to post some short videos on the UT Crops News Blog highlighting some of the more interesting research from this summer.
Thanks,
Larry Steckel

Moth Trapping Data and Southwestern Corn Borers
11
Jun
2020
Just a reminder that moth trapping data are collected weekly and reported on this website under the Quick Links menus (http://www.utcrops.com/BlogStuff/2020MothTrappingData.pdf). Moth catches of bollworm (corn earworm) and tobacco budworm are low, typical of this time of year. However, southwestern corn borer traps in some areas are pretty high. For those with non-Bt corn, this is a cause for concern in those areas (and perhaps others). This first generation will be found feeding within whorls until they begin stalk tunneling. You can read more about their management by Continue reading

Corn Maturity Cutoffs for Herbicides
10
Jun
2020
Due to little time and very few good spray days some corn fields have yet to have their lay-by application. Corn is putting on a new leaf every 3 days with all the heat and water. Therefore time is short before it will be too mature to apply any herbicide safely over the top.
The most asked question “is how large can corn be before glyphosate could potentially cause injury”? The glyphosate label states it can be applied up through the V8 corn growth stage. My experience has been if glyphosate is applied to corn larger than that it can at times cause ears to be barren. This phenomena is difficult to predict ahead of time as it can vary due to maturity of the corn at application, hybrid and weather. Continue reading

Palmer Amaranth Control with all the Uncertainty Around Dicamba

Jun
2020
As most know by now, on June 3rd the U.S. Court of Appeals for the 9th Circuit vacated the labels for XtendiMax, FeXapan and Engenia. The question since is how do we proceed from here controlling weeds in Xtend cotton and soybean?
The folks at the Tennessee Department of Agriculture (TDA) have stated that until they get direction from the Environmental Protection Agency to the contrary, growers can still apply those herbicides according to the label directions. How long this will be is uncertain. It could be just a day, several weeks or depending upon legal maneuvers, well into July. Continue reading
