EPPO Reporting Service (1998/123) : previously considered doubtful, but on the basis of information compiled in 1998, recorded in the two major citrus-producing regions: Tucuman, Misiones and Corrientes. The disease also occurs in the region of Entre Rios where the first symptoms were observed on Valencia Late oranges in 1986/87. In this region, the pycnidial form (Phyllostictina citricarpa) was readily isolated from most symptomatic fruits, but the sexual stage, G. citricarpa has not yet been detected (no details are given for the other regions of Argentina mentioned above). All commercial cultivars are susceptible to G. citricarpa to a varying extent (except sour orange, Citrus aurantium). G. citricarpa can cause significant losses due to premature fruit drop, and refusal of fruits for fresh market (as they are disfigured by the presence of black spots).
