HLB disease severity, expressed as standardized area under the disease progress stairs (sAUDPS), achieved by various SAR inducer treatments at the end of a three-year field trial (2015–2018). Bars represent standard deviations of the mean (n = 6). Different letters on the bars indicate significant difference among the treatments based on Tukey’s HSD test (α = 0.05)
