In this podcast episode, Dr. Nutifafa Adotey and Dr. Jake McNeal addresses post-harvest soil and nutrient management questions sent in by local UT Extension agents.
You can learn more in the publications on estimating supplemental nitrogen following extended flooding and urease inhibitors, as referenced in the episode.

In a previous blog, we referred to recent research that showed fall-applied grass residual herbicides providing good ryegrass control well into the spring. In particular, that research showed that Command, Boundary and the pyroxasulfone based herbicides (Anthem Flex, Zidua) provided the best ryegrass control. Continue reading
Ryegrass has become a serous weed issue in some fields the 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.

Practically every September some growers are dismayed at the vine infestations present at corn harvest. Often, these weed infestations emerged after PRE applied or early POST applied herbicides had played out. They grew very little until August and as the corn dried down and light became more available those established weeds started rapidly growing. Continue reading
Corn harvest is upon us in Tennessee and we have had a few calls about scouting for ear rots and managing mycotoxins. Continue reading
It’s extremely important to know when to stop irrigating corn crop while considering the best kernel development, quality, and yield. Continue reading

Last fall there was a notable amount of Palmer amaranth in many corn fields in areas of the state where we had confirmed dicamba resistance. As a result, we have recently conducted some field screens on these pigweed populations to herbicides used in corn and soybean.
