Citrus huanglongbing (HLB) is the most serious disease of citrus worldwide because of its crop devastation, unknown source of resistance, and difficult and expansive management. Since 2004, when HLB was first reported in Brazil in São Paulo State, approximately three million trees have become affected by the disease and eliminated in attempts to limit spread. Where HLB becomes endemic and there is no effective control by reduction of bacteria inoculum and its vector, the disease progression in the orchard could be relatively fast and the evolution of symptom severity throughout the tree canopy can be very quick, greatly reducing the econonomic life of affected orchards. The affected trees decline and yield is reduced, mainly by the drop fruit early from affected branches. Although the majority of the fruit from symptomatic branches drop before harvest, a significant amount of affected fruit remain attached, are available for harvest, and can affect the juice quality. To quality and compare the effects of HLB on fruit quality of the most important sweet orange cultivars growth in São Paulo, 4 to 6-yr old sweet orange trees from 13 blocks (2 of 'Hamlin', 2 of 'Westin', 4 of 'Pera', and 5 of 'Valencia') were selected prior to harvest. In each block, 14 to 21 HLB-symptomatic trees were chosen. In each tree, the quality of 20 normal appearing fruit from asymptomatic branches and 20 symptomatic fruit from symptomatic branches were assessed. In general, comparing to normal fruit, the symptomatic fruit were smaller, lighter, and had lower juice percentage, Brix, total soluble solids per box, total soluble solids per fruit, and Brix/acidity ratio, and had more acidity. Those effects of fruit quality were less pronunced on early and mid season sweet orange cultivars than on late season cultivar Valencia.
