Grasshopper management in winter wheat
If the surrounding area is a non-crop area, the best treatments would be Warrior (or other lambda-cyhalothrin products) and Asana (or other esfenvalerate products). If the area surrounding the field is pasture, the best products would be Warrior or Mustang MAX. Warrior is the only product that can be used in non-crop areas, pasture, and wheat. To make the most of your residual control when treating borders surrounding wheat fields, apply the border control one to two days before the wheat will emerge.
Grasshopper control around wheat fields can be challenging and the level of effectiveness for any control option will depend largely on the density of grasshoppers. Under very heavy pressure none of the control options will be completely effective, and the loss of some stand on the field margins may be inevitable.
If grasshopper damage reduces stand in the field margins, these areas can be replanted later in the fall after the first hard freeze and grasshopper populations have declined. Grasshopper control in winter wheat will likely be a compromise between effective control and affordability.
