Résumé

Conidia of P. citricarpa (Guignardia citricarpa) did not infect unwounded packhouse-treated citrus fruits (Citrus sinensis cv. Valencia) maintained at -0.5 and 25 °C in artificial and natural inoculation studies, but infrequently produced black spot lesions (G. citricarpa) from which the pathogen could be isolated on artificially inoculated wounded fruit kept at 25 °C. Different treatments (chemicals, warm water and waxing), are studied and their effects are presented.
