A manual outlining the purpose, model, and simplifications used in this program is available here. Documentation of the herbicide data and groundwater hazard calculations for using PEET in Oklahoma are also available.


Computer Platform:

The software is written in Java and runs as a Web Start application. The Java  run-time package and Web Start software are  available free of charge from Sun Microsystems, Inc. The program was developed and tested on various Windows platforms as well as on Linux and MacOS X. We recommend 128 MB or more of Random Access Memory. Approximately 40 MB of disk space is required. 


Link for Java Software:

Before a Java Web Start program can be used on a computer, the supporting software must be installed. This is needed only 1 time per computer no matter how many different applications use it. Sun Microsystems Inc provides this package free of charge at http://java.sun.com/products/j2se or it can be downloaded here. If this is the first time you are using it, just download the file from the site above. Follow the instructions given there for installations. I recommend that you accept the default values proposed in the install process. 


Download/Execute Program:

PEET is designed to support different crops and different geographical areas. These differ in the databases used. Below are links to start PEET for specific areas. Select the version of interest to start the program. If you use the program more than one time, you will be given the option of storing it on your local computer. You can then start the program without coming to this page with a web browser.
