Biological control of Penicillium digitatum on citrus fruits with the antagonistic bacterium Pantoea agglomerans.

The objective was to investigate the biological control potential of Pantoea agglomerans (CPA-2) against Penicillium digitatum in oranges and lemons, in Catalonia and California. The results of laboratory tests showed that Pantoea agglomerans significantly inhibited development of Penicillium digitatum in oranges and lemons. The biological control agent inhibited the pathogen at all studied temperatures. The best results were obtained at 20 and 25 deg C for lemons and at 10-20 deg C for oranges, with 95 and 50% rot reduction respectively. Populations of the antagonist increased on the surface of wounded fruits and remained stable on non-wounded ones. Assays at 20 and 3 deg C demonstrated that Pantoea agglomerans grows actively at both temperatures; the maximum populations were obtained after 1 and 45 days, respectively.
