How to Manage Pests

Pesticides: Water-Related Risks of Active Ingredients

All values are from the Pesticide Properties Database developed and maintained by USDA-NRCS, except where noted. The risk ratings include the NRCS WIN-PST adjustments for application area, rate, and method. Soil type and field conditions may be customized.

Pistachio: Navel Orangeworm

Comparison among pesticides included in UC IPM Pest Management Guideline

when applied under these conditions.

Soil type and field conditions       
  • DEFAULT soil highly susceptible to pesticide movement
  • Field slope is less than 15% (Default)
  • Field does not have macropores (Default)
  • Field does not have a high water table (Default)

Site conditions    Change*
  • Low probability of rainfall/irrigation expected within 7-14 days of pesticide application (Default)

Application conditions    Change^
  • Application to more than 50% of the field (M) (Default)
  • Surface applied (S) (Default)
  • Application rate more than 1/4 pound AI per acre (Q) (Default)

note Application rate, method, soil type, field conditions, and site condition may not be typical for this crop or your location.
To change these conditions to match your own, use the "change" buttons or links.
