How to Use This Calculator

Enter Average temperature (°F), Leaf wetness duration (hours), and Relative humidity (%).
Set Host susceptibility (1-10), Inoculum pressure (1-10), and Consecutive favorable days.
Review Daily infection risk (0-100) and Risk rating (1-5).
Use Temperature favorability (0-1) and Moisture favorability (0-1) to inform your decision.
