DONcast^® is a tool designed for wheat producers to provide a means of predicting deoxynivalenol toxin (DON) concentration in wheat at harvest.

The DONcast^® calculator, developed by Weather INnovations Incorporated, uses actual, forecasted and historical weather data along with field-specific agronometric data to accurately predict DON concentrations in wheat at harvest.

Producers can use this tool to:

1. Make informed management decisions on whether or not to apply a fungicide at heading for reducing potential DON concentrations in mature grain
2. Help strategize which fields with elevated DON potential should be harvested first
3. Provide an advance warning of DON concentrations toward better or alternative market destinations before harvest
