Grasshopper Control in Winter Wheat (And Canola)
Tom A. Royer, Extension Entomologist
Wheat and canola planting is underway. Unfortunately, two years of drought have left parts of the state with an abundant supply of hungry grasshoppers. These grasshoppers will eat until cold weather gives them permanent rest. A plague of hungry grasshoppers equals potential damage to newly-emerging wheat and canola. I would like to outline some management options for grasshoppers in winter wheat and canola.
Option 1 (For Wheat ONLY): A non-chemical option for winter wheat (but not canola) is to double-seed a 60-120 foot strip around the field margin. Grasshoppers move into field margins as their other food sources become depleted. Double-seeded margins produce a thicker plant stand that can hold the foraging grasshoppers. This allows the seedlings in the rest of the field to establish. This can be combined with Option 3. This option is NOT recommended for canola.
