This planting season is off to a very early and quick start. At the current pace many acres will be planted by Easter Sunday. The questions continue to be on how to contend with ryegrass. Continue reading
Planting is well underway! Unfortunately, ryegrass is still present in some fields. Our research has shown this spring that tankmixes of clethodim + glyphosate (Picture 1), Sharpen + glyphosate and Reviton + glyphosate have been the most consistent ryegrass options. Continue reading
Below I have linked the presentations from this year’s Cotton Focus. Many, many thanks to each of the speakers for delivering what many reported was the most valuable program we’ve had in recent memory. Continue reading
This has been an interesting burndown season so far for a couple of reasons. First, the dry weather in late 2025 and early 2026 allowed many acres to be sprayed in January and early February. The number of acres treated during that period is truly impressive. Even better, most of those applications were very successful! Most weeds, including ryegrass, were controlled. Continue reading
We are inviting you to participate in a study conducted by University of Tennessee Institute of Agriculture focused on estimating the economic impact of deer damage to row crops, specialty crops, turfgrass, and nurseries. We tried to make the survey only long enough to collect the data we need to measure the economic impact. We are not asking for any personal information.The findings of this study will be presented to stakeholders and participants in a report and presentations.
To complete the survey, please click on the survey link: https://utk.co1.qualtrics.com/jfe/form/SV_eIIlnfeGcu7HiRw
Thank you and please feel free to contact me if you have any questions.

On January 9th and January 21st, winter canola samples from West Tennessee were confirmed to have white mold (Sclerotinia stem rot). These confirmations are a useful reminder that, as we warm up this spring, it is important to scout fields for this disease, especially leading up to bloom to determine the need for fungicide application.
White mold is caused by Sclerotinia sclerotiorum, a fungal pathogen with a wide host range that can survive for years in soil and crop residue using one of its most identifiable features, sclerotia (hard, black structures on the stem surface – see Image 1). In canola, decisions occur around flowering, where fungal diseases can have the biggest impact on yield.
The agenda for the 2026 Cotton Focus is now available. This event will be held at the West Tennessee Research and Education Center on Thursday, Feb. 19th. Our program will begin at 8 and end with lunch at noon. I look forward to seeing you there!
Fertilizer continues to be one of the largest expenses in row crop production, according to University of Tennessee Field Crop Production Budgets. In season with high-than-normal input cost, nitrogen (N) and phosphorus (P) management offer some of the greatest opportunities for reducing expenses if these fertilizers are managed efficiently. As we head into a new growing season, this blog post outlines key considerations for improving P fertilizer efficiency and maximizing return on investment (ROI). Continue reading
