The black rot is the main disease of kale and its management is still a challenge in urban
agriculture. The aim of this study was to develop a diagrammatic scale to evaluate black rot
(Xanthomonas campestris p v. compestris) severity on kale (Brassica oleraceae var.
acephala) leaves. The diagrammatic scale was developed and validated with eight levels of
severity, ranging from 0.19 to 48.8%. More than 95% of the leaves collected from the field
showed severity levels ranging from 0.1 to 21% and 5% of the leaves showed severities
higher than 22%. The validation of the scale was performed by 10 inexperienced evaluators.
Without the scale, most evaluators overestimated disease severity, whereas the use of the
scale resulted in increased precision, accuracy, repeatability, and reproducibility of the
estimates. In conclusion, the proposed diagrammatic scale proved to be useful for
assessments of black rot severity in kale leaves. The scale may be of interest to researches
performing studies on epidemiology or breeding for resistance. |
