Occurrence of Gray Mold Caused by Botrytis cinerea on Common Fig in Korea

In 2010 and 2011, gary mold was found on common fig fruit grown at the research field of Jeollabuk-do Agricultural Research and Extension Services, Korea. Gray mold symptoms on common fig fruit mainly occured after harvest season until December. The typical symptom included brown water-soaked rot and fruit decay. The diseased fruit was covered by gray to brwon colored conidiophore and conidia. The condiophores were tree shape and measured 15-33 X mm. The nucleotide sequences of the rDNA ITS region obtained from the pure culture of the gray mold on common fig were 100% similar to the sequences of the Genbank accession number HQ171052, EU519210, HQ171053, FN812726, HM849615, and EU563120 of B. cinerea isolate. In phylogenetic tree, the representative isolate was placed within same clade of B. cinera. Based on the morphological characteristics and analysis of rDNA ITS sequence data, the fungus was identified as B.cinerea.
