摘要：
In August 2023, severe symptoms of crown and root rot were detected on blueberry plants in two commercial fields located in Guasave, Sinaloa, Mexico. Colonies with oomycete morphology were obtained and two isolates were purified. The causal agent was identified as Phytopythium helicoides by a combination of morphological studies, pathogenicity tests, and phylogenetic analysis including data from internal transcribed spacer and large subunit sequences. This is the first report of P. helicoides causing crown and root rot of blueberry worldwide.
