WIN-PST3.1
- Windows Pesticide Screening Tool Version 3.1
2
WIN-PST3.1
- Field Office Tools
- Screening tools are available to help address
identified water resource concerns in targeted
areas - The Windows Pesticide Screening Tool (WIN-PST)
evaluates the potential for off-site pesticide
movement in water, and its relative potential to
chronically impact humans and sensitive fish
species(Risk Exposure x Toxicity)
3
WIN-PST3.1
- Evaluates three pesticide loss pathways
- Leaching below the rootzone
- Solution runoff beyond the edge of the field
- Adsorbed runoff beyond the edge of the field
- Includes considerations for
- Climate and Irrigation
- Soil properties (and macropores)
- Field-specific organic matter and topsoil depth
- Apparent high water table
4
WIN-PST3.1
- Includes considerations for
- Crop residue management
- Pesticide application methods
- broadcast, banded, foliar, soil incorporated
- Application Rates
- standard, low, ultra low
- Results designed to guide the site-specific
choice of appropriate mitigation strategies for
all recommended pesticide uses

WIN-PST 3.1
- When the results are analyzed hazard ratings of
very low and low require no action as long as the
chemical is used according to the label and meet
quality criteria for Resource Management Systems
(RMSs) - Ratings of Intermediate or High require
mitigation measures to meet quality criteria
11
WIN-PST 3.1
- High ratings warrant more extensive measures than
Intermediate - Mitigation measures may not be effective for
Extra High rating if resources are highly
sensitive or a high degree of resource protection
is desired - In these cases, an acceptable pesticide with a
lower risk or an alternate method of pest control
may be required
12
WIN-PST 3.1
- Mitigation measures can be found in Table 1 in
the Pest Management 595 Standard - Table 1 identifies management techniques and
conservation practices that have the potential to
mitigate pesticide impacts on water quality

WIN-PST 3.1
- Measures are ranked on their effectiveness to
affect one of the pesticide loss pathways
Leaching, Solution Runoff, and Adsorbed Runoff - Effectiveness is shown as no effect (blank),
slight effect (/-), moderate effect (/--),
and significant effect (/---)
15
WIN-PST 3.1
- Example shows High for Solution Runoff for Fish
Hazard on the A B Brand Copper Sulfate Crystals - Mitigation measures could be Application timing
- Agrichemical Mixing Center
- Filter Strip
