Horseweed recovering from 12.8 ozs of Engenia
Horseweed recovering from 12.8 ozs of Engenia
Ryegrass and poa control can become more problematic when horseweed must also be controlled. Simply dropping dicamba in the tank with glyphosate and/or clethodim to control the horseweed will compromise the grass control of those two herbicides. So, is there a herbicide that can be added to glyphosate or glyphosate + clethodim that will provide horseweed control while not sacrificing ryegrass control? There is really only one option that is in good supply that would fit the bill. Continue reading →
Ryegrass has become a major issue in many Tennessee fields. For managing GR ryegrass, it is best to do it as early as practical and utilize a clethodim + glyphosate tankmix. This tankmix needs to be applied at least 30 days ahead of corn planting to use a clethodim rate that has any chance of controlling well established ryegrass. Continue reading →
Taking soil samples this fall? Why not send them for nematode screening? Take the test and beat the pest! Read on to learn how to take and submit soil samples and the importance of soybean cyst nematode (SCN). Continue reading →
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.
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 →
Symptomology of Command reaching back to control ryegrass
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 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 →
