Fig. 1: Observed disease incidences and numbers of sprays in the 80 experiments.

(a) Individual (per experiment) and overall distribution of disease incidence data for untreated (Unt), calendar-based (Cal) and DSS-based strategies (DSS); (b) individual and overall distribution of the measured differences in incidence between Cal vs. Unt (Cal-Unt), DSS vs. Unt (DSS-Unt) and DSS vs. Cal (DSS-Cal) strategies; (c) individual and overall distribution of the numbers of sprays with Cal and DSS strategies and observed reduction in the number of sprays between DSS vs. Cal strategies; (d) observed difference in disease incidence vs. reduction in the number of sprays for DSS vs. Cal strategies. Each point represents a pair of plots (DSS, Cal) within the same experiment. Box-and-whisker plot elements for (a)–(d): central line represents the median value; box limitis represents the first (Q1) and the third (Q3) quantiles; upper whisker represents min(max(x),Q3 + 1.5 IQR; lower whisker represents max(min(x), Q1 − 1.5 IQR; IQR = Q3 − Q1; outliers are represented by dots.
