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.
In response to requests, the EPA announced April 28 in an EPA Update that it is extending for an additional 30 days the public comment period on the proposed regulatory decision to register dicamba to control weeds in cotton and soybean genetically engineered (GE) to tolerate dicamba.
Cold, wet conditions this spring may have delayed some growers from applying burndown herbicides when they would like to for utmost effectiveness. Low temperatures and wet weather can negatively impact herbicide performance.
DiFlexx™ DUO is a herbicide for control of annual broadleaf and grass weeds in field corn, corn grown for silage, popcorn, and seed corn and for post-harvest burndown weed control. It is a premix of DiFlexx (dicamba: 19.73%) and Laudis (tembotrione: 2.83%).
Several new herbicides have been registered for weed control in corn. These herbicides do not have an active ingredient with a new mode of action, but rather are pre-mixtures of existing herbicides. They can provide excellent weed control if applied according to label directions. A season-long weed management plan should include herbicides with multiple modes of action.
