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.
As wheat is approaching flag leaf stage in Tennessee, start scouting if you haven’t already for disease. Depending on variety susceptibility you may already see powdery mildew and/or wheat blotch (Septoria and/or Stagonospora blotch); but if no disease present start considering Fusarium Head Blight management.

Ryegrass has become a serous weed issue in some fields that past couple of years. A major reason for this is that much of it is now glyphosate-resistant. Even if clethodim is used rather than glyphosate often it is applied on ryegrass sometime in late March through April when the grass is too well established to provide consistent control.

The two best fall-applied options for ryegrass and poa 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 new use pattern 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
The results of the 2023 Official Variety Trials; Wheat are in. This information will be available on our variety testing site search.utcrops.com soon and can also be accessed through your local County Extension Office.

In fall of ’22, we planted 21 wheat varieties from 7 companies in 8 county trials, and the yield results in. Very good yields again this year, especially with early concerns from some delayed planting last fall combined with a wet spring and late freeze that hit much of TN. The varieties we are planting in TN are much better than what we had just a decade ago! These varieties have been selected to be more suitable to our wetter climate and our yields seem to be more stable and predictable based on management and inputs.
With our 21 varieties at 8 locations, we had an overall average of over 92 bu/ac, with location averages ranging from 136 to 61 bu/ac.
All CST’s are: on-farm, large strip trials and are managed and maintained by each county’s cooperating producer/s. Thank you to all the County Agents and growers who contributed to this data.

So far only some bacterial streak and Septoria/Stagonospora have been reported in Tennessee wheat. Continue reading
We have gotten several reports of wheat showing metribuzin injury this week. In some cases it clearly was caused by metribuzin (Picture 1). In other cases, the visual injury would suggest frost damage (Picture 2). Continue reading
