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.

Ryegrass and Poa Management in Wheat
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

2023 County Standardized Trials-Wheat Data
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.

Metribuzin Injury in Wheat
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
Weed Management Strategies Following Early Corn Harvest that will be Planted to Wheat
The long hot and mostly dry June and July have driven a good bit of our corn crop to premature maturity. Similar to the drought of 2012 when the corn crop burned up, I would expect a good bit of the prematurely matured corn will be harvested in August and early September. In 2012 a good bit of that early harvested corn was planted to wheat well before the fly free date. I expect many will manage this disappointing corn crop similarly this fall. Continue reading
2022 County Standardized Trials-Wheat Data
This year’s County Standardized Trials (CST) Wheat data are in. In fall of 2021, we had 7 successful wheat variety test plots planted, with 13 varieties coming from 5 industry leading seed providers. Summer 2022 harvest resulted in: locations averaged from 38 bu/ac to 120 bu/ac with an overall average across locations and varieties of 88.4 bu/ac. A full report including OVT data is available at search.utcrops.com.

The CST program utilizes County Agents and local producers to evaluate variety performance in on-farm, large strip trials. Each trial is a minimum length of 300 feet and trials are managed using the producers’ chosen practices in accordance with UT recommendations. A special thanks to all Agents and producers involved, along with our seed industry partners!!
