As the earliest planted soybeans in Tennessee push into beginning seed development and beyond, there are some soybean diseases that are becoming more notable. The good growing conditions most have experienced promote good yields and diseases – correctly identifying these diseases are crucial to implementing the best management practices to protect yield.

Questions continue on what to do with late season pigweed breaking through the crop canopy. Most questions have been in cotton where escaped pigweed are more visible. More questions recently have been in soybean as escapes are poking up through the canopy (picture 1). Continue reading
Reports of fall armyworms are emerging from Arkansas this week. While populations remain low, larvae have been found in rice and soybean fields with significant grass weed infestations. To date, no armyworms have been reported in Tennessee, but late July is historically when populations begin to appear. Continue reading
UT’s ‘Top Bean’ Contest, sponsored by TN Soybean Promotion Board
Our contest has been growing each year, with over 50 entries submitted last year. This is a great opportunity for producers to show off some of their high yielding fields while giving us an idea of their practices used to achieve them.
Growers are encouraged to work with their local county Extension agent to enter their best irrigated and dryland fields and compete for ‘Top Bean’ in the state. Tennessee is divided into five yield districts for the contest. District winners will receive awards and all district winners will compete for state winner in irrigated and dryland production.
Producers (farm entity) are allowed to submit in two categories; one irrigated submission and one non-irrigated submission. As so, a producer may only submit one entry per category. Producers may submit in two districts if they submit an irrigated from one district and a non-irrigated from a different district.
Agents with access to a weigh wagon can use their wagon to weigh contest harvest, and document weight on a new UT weight certification form. Producers and agents without access to a calibrated weigh wagon should continue to weigh harvested seed at a nearby certified scale and include a copy of the weigh ticket to certify weight.
An entry form acknowledging your intent on entering must be submitted by September 1st. Please get with your local County Extension Office for more details and to submit your forms.
All the rules and information on how this contest is ran are attached below.
Use these forms at harvest to submit a completed entry. Due December 8th, 2026

UT’s Soybean Scout Schools will be held in July (see details below). These field-side programs cover the basics of soybean growth, scouting, pest identification, and general management. Pesticide recertification and CCA CEU points will be available. Scout Schools are offered free of charge with sponsorship from the Tennessee Soybean Promotion Board. Registration is not required. Participants will receive a scouting notebook and a sweep net while supplies last.
It is back to the future in West Tennessee. Replacing hoses and solenoids on hoods and shovels on cultivators was common back in 2008 to 2010 when glyphosate failed on pigweed. There have been recent reports of folks trying to get hoods and field cultivators in working order. The reason for this is they are trying to knock down Palmer amaranth that has escaped dicamba + glufosinate applications. Continue reading
As we near the middle of July and soybean fields move into pod formation, it’s time to decide whether a fungicide application is needed. When making that decision, we need to consider the cost of fungicide application, the crop price, and disease pressure, meaning its potential to rob yield. Continue reading
Scattered rains have accumulated over the past week, with many receiving several inches or more. With even more rain in the forecast and many of our acres quickly entering their second and third week of bloom, the question of the week has been what to do with plant growth regulators. In contrast to previous years, the introduction of the active plinazolin (Vertento) has created a more interesting question- what can we do, from a plant growth regulator standpoint, to take full advantage of the long residual control window provided by this new product? In this blog, I outline the best approach to balance a possible opportunity to save an application cost with the risk of being too aggressive. Continue reading
