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.

The two best fall-applied options for ryegrass and poa control 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 use 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
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
I’ve spent the better part of the past three days walking cotton throughout West Tennessee, and while I’m pleasantly surprised by our earliest planted acres, I’m concerned the crop in many areas may fall well-short of what we might have expected at the end of July. In this blog, I briefly share my thoughts on how I would approach terminating irrigation in 2024 and what I believe may be our best first-shot blend for defoliating our earliest acres.

The extended planting season this year has resulted in an extended weed management season. Even with this in mind it has been surprising about questions this late in August on what can be sprayed on soybean to control pigweed, morninglories and grass. 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
