In “Pecan Scab Severity–Effects of Assessment Methods,” Bock, Wood, and Gottwald compare a Horsfall-Barratt category scale with a nearest-percent-estimate system for rating symptom severity on pecan fruit caused by the pecan scab pathogen, the fungus Fusicladium effusum. Both experienced and inexperienced raters assessed photos of scab on pecan fruit valves. The result was that ratings according to both systems and rater groups took about the same amount of time, and there was no advantage of either system regarding accuracy or reliability, leading to the conclusion that categorical rating offered no advantage over percent-disease estimation for fruit in this pathosystem.
