Expansion and Comprehensive Evaluation of the Peacock Eye Disease Management (PedMan) System across Olive Cultivars Differing in Susceptibility to Venturia oleaginea

PedMan expanded for olive cultivars with different susceptibility to Venturia oleaginea achieved 90.9% correct fungicide recommendations across 33 commercial field trials.

• Why it matters: Spray timing for peacock eye disease relies heavily on fungicides, and a one-size-fits-all warning system may not match cultivar-specific infection risk.
• What they did: The team adjusted PedMan’s rainfall and temperature alert criteria using sensitivity analysis, then tested it under natural infection in 33 field trials by comparing leaf abscission between fungicide-treated and untreated trees.
• The result: With 30 of 33 recommendations correct, sensitivity was 87.0% and specificity and positive predictive value were both 100%, supporting reliable cultivar-specific management.
