There have been increasing issues with perennial vine infestations in soybean and corn fields in recent years. The two most commonly found species are honeyvine milkweed and trumpet creeper. Others that show up less frequently are hedge bindweed, burcumcumber and Carolina coralbead. Continue reading
2025 CST Wheat Results
Last fall, we planted 10 locations and had 6 of those make it into the table. We lost the others to this wet weather that seems to stick around. Overall, better yields around W. TN than I was expecting. We had several acres planted a little later than hoped for and then a wet sparing had quality and yield goals questionable.
80 bu. average across our 18 varieties in 6 locations. A tight group with a 10 bushel range keeps the mean separation close at a 95% confidence interval.
Yields have been adjusted to 13.5% moisture. Each variety is evaluated in large strip-plots at each location, thus each county test is considered as one replication of the test in calculating the average yield.
Statistical analysis is conducted at 95% confidence interval. Varieties with the same MS letter are not significantly different.
Official test weight of No. 2 wheat= 58 lbs/bu. TWT was averaged from 5 locations.

Thank you to all those producers, agents, and industry for your support with our CST programs.
Please contact your local County Extension office for more information.
While wheat varies in growth stage across Tennessee, it’s time to consider fungicide and scout for diseases. To date, little to no disease has been reported in wheat fields in Tennessee. Continue reading
In this podcast episode, Dr. Nutifafa Adotey and Dr. Jake McNeal addresses post-harvest soil and nutrient management questions sent in by local UT Extension agents.
You can learn more in the publications on estimating supplemental nitrogen following extended flooding and urease inhibitors, as referenced in the episode.

I’ve gotten a few calls on fall armyworms (FAW) infesting cover crop wheat and production wheat. FAW, in large enough numbers, will defoliate a wheat field if left uncontrolled and UT’s FAW threshold is four worms per square foot. To date, pyrethroids have been providing satisfactory control of FAW in soybeans and pastures and the same can be assumed for wheat. Pyrethroids are the most economic option but also provide the shortest residual (3-5 days). Other options include Vantacor, Besiege and Radiant/Blackhawk. Insecticide seed treatments for Hessian Fly and/or aphids won’t control FAW and if numbers exceed threshold a foliar spray may be required. Another option is to delay wheat planting until after October 15th (Hessian Fly Free Date) as infestations of fall armyworm almost always occur in early planted wheat, especially for wheat planted in September.
The two best fall-applied options for ryegrass and poa control in wheat are Anthem Flex and Zidua. Pyroxasulfone is providing the grass control in both these herbicides. Anthem Flex can be applied as a true PRE right behind the press wheel. Keep in mind there is some chance of wheat injury from this use if a rain occurs shortly after planting. As such, if rain is in the forecast wait and apply it later as a delayed PRE or early POST. Continue reading
This year’s County Standardized Trials, Wheat Program tested 23 varieties of Soft Red Winter Wheat in 10 locations. Seven of those locations where used to compile our variety recommendations for the 2024 fall planting. Over all, yields across varieties and locations averaged just over 76 bu/ac, with an average of 10.4% moisture and 55.1 lb testweight.
Thank you to all the producer who put these trials out and the County Agents who organized and oversee these variety plots. Also, a special thanks to our cooperating companies who supply seed and genetics to test in our environment. Wheat yields have increased dramatically over the years, better genetics and breeding programs along with state and local testing are proving to add weight to the combine and increase profits for wheat growers in TN.
If you are interested in having a County Standardized Trial (Corn, Soy, Cotton, Wheat) on your farm, contact your local County Extension office for more details.
This Fall, contact your seed suppliers and request wheat seed from the list above with confidence from our unbias variety testing program.
Most wheat in Tennessee is in the flowering period, the highest period for susceptibility to scab/FHB infection. There are multiple factors that can contribute to a field’s Scab/FHB risk.
