Abstract:
We have developed a web-based software tool for evaluating the potential risk of
pesticides on the surrounding environment. The software tool is called Web-based
Pesticide Screening Tool (Web-PST). It uses the formulas and standards specified by
the Soil/Pesticide Interaction Screening Procedure Version II (SPISP II). Web-PST
closely models the stand-alone Windows application Windows Pesticide Screening
Tool (WIN-PST). For a given pesticide, a soil type, and a cultivation practice, Web-PST
evaluates the likelihood of pesticide loss and its potential risks to both humans and fish.
In addition to hazard ratings, Web-PST allows the user to generate a list of pests that
can be controlled with a given pesticide. It also generates a list of the types of
agricultural situations where the pesticide is commonly applied.
