WIN-PST
• NAPRA (National Agricultural Pesticide Risk Analysis) Team:
• NRCS– Joe Bagdon Pest Management Specialist– Eric Hesketh Soil Scientist
• University of Massachusetts Extension– Steve Plotkin WQ Specialist– Morgan Hugo Software Engineer
WIN-PST• WIN-PST is Pesticide Screening Tool:
– Easy to use – Self contained
• Pesticide data
• Soils data
• Toxicity data
– Provides risk rating classes (e.g., High, Intermediate, Low…)
– Helps planners determine when mitigation is needed– Available for NRCS Field Office use now
• NPURG– SPISP 1
• Leaching Loss • Surface Loss• Foliar
Application
• WIN-PST– SPISP 2
• Leaching Loss• Solution Runoff• Adsorbed Loss• Management
– Rate – Residue– Banding– Incorporation– Irrigation– Rainfall
• Toxicity
• FOCS-PST– SPISP 2
• Leaching• Solution Runoff • Adsorbed losses• Impossible to
use
• WIN-PST– SPISP 2
• Leaching Loss• Solution Runoff• Adsorbed Loss• Management
– Rate – Residue– Banding– Incorporation– Irrigation– Rainfall
• Toxicity
WIN-PST
• Uses SPISP 2 (Soil/Pesticide Interaction Screening Procedure version 2)
• Adds Management and Toxicty
• SPISP 1 in NRCS field offices 1988
• NPURG uses SPISP 1
Soil Ratings Pesticide Ratings
Interaction Rating
Toxicity
Hazard Rating
WIN-PST
• “Interaction” Hazard Categories
– Low
– Very Low Mitigation not necessary
– Intermediate Mitigation - basic level (1 or 2 practices)
– Extra High Mitigation may not work
– High Mitigation - higher level (3 or more practices)
WIN-PST
• Educate ag. producers- hazards of pesticide loss – Factors that influence loss– Factors that influence ‘hazard’
• Identify potentially high risk soil/pesticide combinations
• Design and apply conservation practices & mitigation techniques that reduce hazardous pesticide losses
