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

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. Continue reading
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
