Previous records of Guignardia on citrus in some countries may involve the non-pathogenic species Guignardia mangiferae. The situation in Hong Kong, Swaziland and Nigeria is still unclear. The distribution in this summary table is based on all the information available.

When several references are cited, they may give conflicting information on the status.

Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. A method for detection of G. The method is sufficiently simple to allow deployment of the test in the field, for example, in the course of import inspections. Often black spot can be identified with considerable certainty if hard spot lesions with pycnidia are present.

However, freckle spot, false melanose and virulent spot can be confused with many other diseases and injuries Kotze, Once a species of Guignardia has been isolated from symptomatic tissue, the species involved must be determined. Identification of species of Guignardia from citrus requires isolation of the slow-growing fungus and comparison of several of the above-listed traits to verify the identity. Proof of pathogenicity requires inoculation of fruit or leaves and an incubation period of weeks or months before symptoms appear Kotze, Thus, detection and identification is currently difficult and time-consuming.

However, species-specific primers from the ITS region and other regions of the genome have been developed Sanders et al. These primers are quite reliable for differentiation of the two species when used with pure cultures of the fungus. If they prove successful for detection and identification of species using colonized plant material they should greatly speed diagnosis of black spot.

Polymerase chain reaction PCR can be used to diagnose G. Nonpathogenic isolates of the citrus black spot fungus, Guignardia citricarpa, identified as a cosmopolitan endophyte of woody plants, G.
