Resumo: | The chemical treatment evaluation in the field to control post-harvest fruit anthracnose (Colletotrichum gloeosporioides) requires a suitable disease incidence assessment on harvested papaya (Carica papaya) fruits. The minimum number of papaya fruit harvests was determined for valid treatment comparison in field trials for anthracnose chemical control. Repeatability analysis was done using previously published data. The coefficient determination (R²) estimate range, using four methods, and based on means of 12 assessment times, was 92.58 &lt; R² &lt; 94.45%. The number of assessment times required for R²=90% varied from seven to nine. The R² values of 85.1 &lt; R² &lt; 91.3% estimated by ANOVA suggested that any seven successive assessment times were sufficient for treatment comparison.
