Sour rot, incidet by Geotrichum candidum Link. ex Pers., is an important postharvest disease of citrus fruits, because of the rapid growth of the pathogen, its ability to spread by contact and because no postharvest treatment, except cold temperature, is known to control it. The inoculation of wounds on the lemon peel, made with a puncture tool, with a conidial suspension of the pathogen frequently has resulted in partial or variable sucess. This constitutes a limiting factor in tests with fungicides to control the disease. Green mold, incited by Penicillium digitatum Sacc., is a major postharvest disease of citrus fruits in all the citrus-producing areas of the world. Of the fungi present on the lemon fruit surface, Cladosporium spp and Aureobasidium spp were most common, comprising 85% to 90% of the population. Rhadotorula spp, Aspergillus spp, Penicillium spp, Rhizopus spp, and Monilia spp also were present on the lemon fruit surface. None of the fungi isolated from the lemon fruit surface was pathogenic to lemons. Rhadotorula sp isolate Rh 14 was antagonistic to P. digitatum, when inoculated in mixture with it, causing reduction of infection from 79% to 23%. Rhadotorula spp comprise less than 5% of the fungi of the surface of lemon fruits. |
