The aim of this study was to determine symptoms and causal agents associated with clove death syndrome, and factors related to disease severity. This research was carried out through field observations on the severity of the disease, associated symptoms, and interviews with farmers regarding the cultivation techniques carried out. The results of the study were presented quantitatively with cross tabulations for the three research location districts, and 1 location, including Trenggalek District, complemented with correspondence analysis using the Chi square test. From surveys in three districts, Trenggalek, Semarang and Tegal, the highest probability of symptoms associated with clove death syndrome was stem borer + canker, stem canker, and stem borer + canker, respectively. Based on the results of the correspondence analysis in Trenggalek District using the chi square test (χ2: p <0.1), some factors, i.e. plant age, cropping patterns, doses of animal manure, Phospate (P) fertilzer dosage, weed conditions in the field, and frequency of weed control showed an association with the severity of the clove death syndrome. Further experimental research is needed to ensure that these factors are related to the severity of the disease syndrome.
