How to Use This Calculator

Enter Field size (acres), Expected infestation rate (0-1), and Desired margin of error (0-1).
Set Confidence level (1=80%, 2=90%, 3=95%, 4=99%), Pest generation time (days), and Time per sample point (minutes).
Review Sample points required and Grid spacing (feet).
Use Grid spacing (meters) and Scouting interval (days) to inform your decision.
