This spreadsheet model is intended to be used in as a supplement to FEFO 05-05 : A Soybean Rust Scenario: 2005 Crop Year Decision Making in Illinois.

The model allows the user to perform a sensitivity analysis of soybean rust impact for three acreage scenarios: traditional 50% corn - 50% soybeans (50:50), 100% corn (100:0) or 75% corn - 25% soybeans (75:25).

These three scenarios are defined by the tactics employed in the 2005 crop year. For 2004 and 2006, the model employs a 50:50 ratio for all three scenarios.

For guidance in selecting parameters, the user should see Figure 2 in the FEFO document mentioned above. Variables in the right quadrants are used in this model. You may generally consider price gaps, yield ratios and yield drag changes or spraying cost changes using the tool menu.
