HopperShield™ Potato Leafhopper-Resistance

W-L potato leafhopper—resistant alfalfa varieties are a clear choice for growers who want to minimize the impact of this damaging insect. Many farmers rely on these varieties because of convenience and agronomic performance, even under heavy leafhopper infestations.

  • Producers in regions of high leafhopper pressure can expect higher yields, better forage quality and reduced insecticide cost when they use our newest leafhopper-resistant varieties.
  • W-L HopperShield™ alfalfas can now offer more than 85 percent resistance to this harmful pest.
  • An Iowa State University study showed that the economic spray threshold (the point at which leafhopper infestation is high enough that spraying makes financial sense) is 10 times higher than that of nonresistant varieties.
