Balancing Sample Size, Accuracy, and Time when Monitoring Stink Bug Damage

Whole field characterization of stink bug damage in cotton poses a significant challenge to crop consultants and growers.  While examining internal boll damage is accurate, it has not been widely adopted because of the significant time commitment.  An alternative sampling method, enumeration of external lesions, is faster but not as accurate.  This presentation will utilize inverse prediction confidence intervals to document how sample size and accuracy are related when classifying boll damage relative to a sampling threshold using the external method.
