Experiences on Hlb (huanglongbing) Symptoms Detection in Florida

Throughout the history of citrus production in Florida one of the diseases with a major impact has been the Asian form of citrus greening (HLB), which was first detected in 2005. As a response to this introduction, new survey and detection methods had to be developed utilizing field observations directed not only to corroborate symptoms already reported in the literature, but to describe any variations in symptomology observed on the different citrus varieties and their relatives growing in the area. Field and lab symptom studies were performed on Citrus aunantiifolia (Key/Mexican lime), C. aurantiifolia ( Persian lime), C. aurantium ( sour orange), C. jambhiri (rough lemon), C. limettioides ( Palestine sweet lime), C. limon (lemon), C. limonia (Rangpur lime), C. maxima (pummelo), C. macrophylla (alemow) , C. x paradisi (grapefruit), C. reticulata (mandarin-tangerine), C. reticulata X C. x paradisi (tangelo), C. sinensis (sweet orange), and Poncirus trifoliata (trifoliate orange) plants. The blotchy mottle symptom observed on the study plants support those described in the literature as the most important diagnostic symptom. Based on the results, training activities and materials were developed to compliment survey activities and sample collection protocols used to delimit and monitor the disease spread.
