A protocol was developed to isolate DNA from orange juice and detect titer of Candidatus Liberibacter asiaticus (CLas), the presumed pathogen associated with citrus Huanglongbing (HLB) disease by real-time PCR. To obtain quality DNA, new methods were used to remove pectin and unidentified inhibitors.
