Abstract: A standard area diagram set (SADs) for severity evaluation of septoriosis (Septoria passiflorae) in fruit of sour passion fruit (Passiflora edulis Sims) was developed and validated in this study. The SADs presented eight severity levels (0.3; 0.5; 1; 2; 4; 10; 18; and 30%). For its validation, 20 raters were divided into groups (G1 and G3, inexperienced; G2 and G4, experienced) who initially estimated the disease severity without the aid of the SADs. Subsequently, G1 and G2 performed the second evaluation with… Show more

“…When the SADs was used by G3 and G4, the overestimation trend was maintained. However, the overestimated values and number of evaluators who presented this tendency reduced, as verified in previous studies (COSTA et al, 2019a(COSTA et al, , 2019b. Except for evaluator 14, all inexperienced evaluators had intercept values equal to 0 (P≤0.05), i.e., without constant errors.…”

“…These methods showed an improvement in the accuracy and precision of estimates, corroborating studies that report the relevance of the SADs as tools to standardize visual estimates of disease severity and to train inexperienced and experienced evaluators alike (DEL PONTE et al, 2017). This also can be applied to the passion fruit crop (FISCHER et al, 2009;COSTA et al, 2018;MONZANI et al, 2018;COSTA et al, 2019aCOSTA et al, , 2019bCOSTA et al, , 2019c. The use of the SADs resulted in a reduction of the constant and systematic errors, which are components of accuracy.…”
