Potato Bacterial Soft Rot Survey

Wanted: Wet, soft and slimy potatoes

Bacterial soft rots and blackleg are common potato diseases caused by a number of different bacteria in the Pectobacterium and Dickeya genera. In recent years the bacterial species affecting potatoes has been changing, with some more aggressive species emerging making management challenging.

In 2024 we are conducting a survey to test the different types of soft rot bacteria that Ontario potato growers are dealing with.

If you have any samples of soft rot in received seed, last years storage or blackleg symptoms showing up in the field, please reach out to have your samples submitted. Samples are free of charge and we can coordinate pickup.

To submit samples, please contact Dennis Van Dyk (519-766-5337, dennis.vandyk@ontario.ca)
