Use your yield monitor to mark locations for more than just rocks and evaluate crop performance.

University of Nebraska-Lincoln greenhouse studies have confirmed a Palmer amaranth population resistant to postemergence application of atrazine and HPPD-inhibiting herbicides (Callisto, Laudis, Armezon/Impact). This is the second report (after Kansas) of a Palmer amaranth population resistant to atrazine and the HPPD group of herbicides.

We have published articles about fall herbicide treatments in C.O.R.N. over most of the last five years or more. Readers can check the archives for those articles, as our suggestions about fall weed control have not really changed much from year to year. Maybe the best thing we can do here instead of regurgitating the same information is to list some of the questions we have received this year about fall treatments, with answers of course.

University of Nebraska Extension shares some tips and considerations for planting cover crops into storm-damaged fields.

This is the time of the year we need to pay extra attention to reducing spray drift because some of us are applying herbicides that could create serious problems if the herbicide drifts away from the application site and deposits on crops sensitive to that particular herbicide, such as Dicamba products or Glyphosate.

Winter annual weeds, such as field pennycress and henbit, have grown into a serious management concern in no-till corn and soybean for some growers.

Prolonged wet periods often disrupt the normal sequence of field operations.

As more farmers use vertical tillage to manage crop residues or to mellow the seedbed prior to planting (especially soybeans), questions have arisen about possible impacts of using these types of tillage operations in combination with certain soybean herbicides.
