Abstract
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.
期刊介绍:
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
