    Economic (Treatment) Threshold Used in the Russian Wheat Aphid Calculator
  • The EconomicThreshold is based on yield loss caused by RWA, control cost and the value of the wheat crop.
  • It estimates potential yield loss from RWA infestations based on research conducted in Texas and Colorado over many years.
  • Your control cost and crop value are variables.
  • Control cost is based on insecticide price and application cost.
  • Crop value varies depending on the price of wheat from year to year and month to month, so you might want to run the Russian Wheat Aphid Calculator more than once using various realistic crop values to see if the economic threshold changes.
  • The threshold usually will not change much for various trial values of crop price, and you can use the value you feel comfortable with and expect good results.
