In its latest issue, Molecular Plant Pathology has published a list of the top 10 oomycete pathogens based on scientific and economic importance, as voted for by 62 scientists. This is the latest of the journal’s “Top 10” articles which have previously covered plant pathogenic fungi, bacteria and viruses.

Oomycetes, also known as water molds, are often likened to fungi as they resemble filamentous fungi, and have similar feeding and reproduction methods.

Below you will find more information about the “Top 10” plant pathogenic oomycetes, with links to further information available on the Plantwise knowledge bank.   Continue reading
