Blossom blight was documented in some strawberry production fields in Watsonville in 1996 and 1997. Xanthomonas fragariae and Cladosporium cladosporioides were identified as the causal organisms. This is the first documentation of the two organisms causing blossom blight of strawberry in California. This is also the first report identifying C. cladosporioides as a pathogen of strawberry.
