• 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

Soil Ratings Pesticide Ratings

Interaction Rating

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
