Resumo
Citrus black spot (CBS) is a fungal disease, caused by Guignardia citricarpa and affects practically all citrus
species of economic importance, especially sweet oranges. It has become a serious, widespread problem for
citrus production in South America. It causes lesions on citrus fruit peel and leaves and can induce fruit drop
before maturity. Fruits from citrus areas affected by CBS represent a risk for introduction of this pathogen into
new areas. European Community and United States severely limit importation of fresh citrus fruit from those
countries were the disease is present. Various treatments have been explored to reduce the risk of introduction of
CBS into countries that are currently free of this disease. E-beam processing has been successfully used to
inactivate food spoilage microorganisms, including bacteria, yeasts and moulds. Ionizing radiation treatment
has been known to extend the postharvest life of many tropical and subtropical fruits. Irradiation is the most
recent commercial phytosanitary treatment for fresh commodities. The aim of this study was to assess the effect
of electron beam processing on the viability of G. citricarpa. Isolated fungi from naturally infected oranges
were irradiated with 2.5, 5.0, 7.5, 10.0 and 12.5 kGy using an electron beam irradiator (Radiation Dinamics Co.,
model JOB-188, New York, USA). Irradiation appeared to be a useful alternative as a phytosanitary treatment to
control citrus black spot dissemination.
