Teixeira, M.A., Bettiol, W., & Cesnik, R. 2001 Patogenicidade do fungo Colletotrichum gloeosporioides, patogeno de O. praelonga, para folhas, frutos e flores cit. [Pathogenicity of Colletotrichum gloeosporioides, Orthezia praelonga, pathogenic agent, to citrus leaves, flowers and fruits.]. Summa Phytopathologica 27(4): 352-357.

Notes: The pathogenicity of C. gloeosporioides [Glomerella cingulata], a pathogen of O. praelonga, to different tissues of citrus, i.e. leaves, flowers and fruits of 'Pera' orange, 'Cravo' lime and 'Cravo' tangerine, was evaluated. The pathogenicity of these isolates were compared with that of Colletotrichum sp. isolated from injured petals of citrus (CCC) and that of C. acutatum (CCA), the causal agent of post-bloom fruit drop of citrus. The isolated fungi did not show any evidence of pathogenicity to citrus leaves. On the other hand, all inoculated fruits exhibited symptoms typical of anthracnose, but the average diameter of injuries for each citrus sample varied with the isolated fungi studied. Flowers inoculated in the field did not show any symptoms of floral rot even after one year following inoculation. Under greenhouse conditions, inoculation of flowers with CTAA4, CTAA5, CCC and CCA resulted in typical symptoms of post-bloom fruit drop. The results are discussed in relation of the potential use of C. gloeosporioides for the biological control of O. praelonga in citrus.
