This has ,clearly, been the worst year for ryegrass in the state in both corn and wheat. There are a good many corn fields that are clean where the burndown was glyphosate + clethodim. Fields where dicamba was added in the burndown are, in most cases, the most infested with ryegrass. As mentioned in a previous blog, other than just going out and spraying the typical POST corn application and hoping that pushes the ryegrass on to maturity there is no real solution to controlling it.

To date there have been additional reports of stripe rust in West TN and some fields with bacterial leaf streak. As wheat starts to bloom, continue to monitor the Fusarium Head Blight(FHB)/Head Scab model to assess if fungicide application is needed. Continue reading
The constant word I am hearing from retailers is that many herbicides are in tight or limited supply going into the spring. This all started back in late January when the most commonly used spring wheat herbicide, Axial Bold, sold out quickly and was followed shortly by Osprey. This was followed with reports of 2,4-D being in short supply. Continue reading
Tennessee fields annually turn a purple color around April 1. The weed henbit (Lamium amplexicaule L.) is the main cause for this color. It has distinct purple flowers and is one of the most commonly found plants in our row crop fields. However, there is a close cousin to henbit, purple deadnettle (Lamium purpureum L.), that is also adding to the purple color in many fields. Continue reading
If you haven’t noticed, our UTcrops.com website has gotten a facelift. You may not recognize it when you first visit us at https://utcrops.com/. However, it’s organized similarly to the old version. I’m sure there are a few bugs that need to be fixed, but take a look! This site gives you ready access to essentially all UT resources related to row crop production.
A special thanks to all cooperators, agents, and all others who make the County Standardized Trials Program a success.
With Covid limiting in-person meetings and office visits, I want to make available the 2020 CST handout. The above link is available for you to use in assisting variety/hybrid selection for the coming season. Agents, feel free to print and send out or send this attachment to your row crop producers via email. The full report above contains data from 2019 and 2020 for corn and soybean, 2020 Wheat, and 2020 Cotton.
The following links are segments of the full report to simplify searches through all 2020 CST data.
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
County Standardized Trial (CST) Wheat Results are now available. The 2019 planted wheat crop had it’s challenges to say to the least. Between delayed harvest of the 2019 crop, wet fall, wet spring, late freezes etc. this crop had everyone guessing how it would turn out.
The CST program was able to use data collected from 7 locations (Carroll, Fayette, Gibson, Madison, Moore, Weakley, WTREC) to compile this dateset representing 18 varieties commonly available to TN producers. Overall, the varieties averaged 70 bu/ac with a location average range from 52-97 bu/ac. Varieties are separated statistically at a 95% confidence interval indicated by the Mean Separation, “MS” column. Varieties that have the same letter in the MS column are not significantly different from each other.
CST plots are on-farm large strip trials in design, with a minimum plot length of 300 ft. These plots are conducted using common agriculture practices supported by UT recommendations. Special thanks to everyone involved, especially those cooperating producers and County Agents who make this possible .
