Planting Interval of Corn and Soybean after 2,4-D/ Dicamba Burndown Application

April 7, 2017
With cold, wet conditions in March, many producers may be facing a smaller than expected window for making their herbicide burndown applications in April. This makes timely applications now even more important to provide for a proper interval before planting this year.

Status of Herbicide-Resistant Weeds in Nebraska

March 20, 2017
Nine weed species in Nebraska have now evolved resistance to at least one group of herbicides. Six weed species — common ragweed, common waterhemp, marestail, kochia, giant ragweed, and Palmer amaranth — have confirmed resistance to glyphosate. Rotate herbicide sites of action and weed control practice to avoid contributing to this trend.

When is a Good Time to Scout and Control Glyphosate-Resistant Marestail?

March 8, 2017

Marestail, also known as horseweed or Canada fleabane, is a winter or summer annual weed in Nebraska. Historically, marestail was found in waste area, field edges, along roadsides, and railway tracks; however, no-till crop production systems over the last 20 years favor marestail germination and establishment in agronomic crops in Nebraska.

2017 Chart for Selection of Herbicides Based on Site of Action

February 2, 2017
Management of glyphosate-resistant weeds is now the greatest challenge for Nebraska crop producers and land managers. The 2017 Herbicide Classification Chart from Take Action Against Weeds is an easy means for identifying herbicide site of action to avoid repeated use of the same action on the same field.
