Influence of pH on the clubroot pathogen: are there pH-insensitive strains?

The Challenge

While liming represents a potential tool for clubroot management, the effectiveness of increase pH in controlling different clubroot strains, and the potential risks of liming as a clubroot management strategy, are not known.

The Project

Determine if the effectiveness of soil pH amendments for clubroot control depends on the pathotype present and if liming can inadvertently select of pH-insensitive strains of the pathogen.

The Results

This section will be updated upon completion of the project.

Grower Benefits

An understanding of the effectiveness of liming to control different pathotypes will help in decision-making, since liming to increase soil pH can be costly and will not produce satisfactory results if the field pathotypes present are less sensitive to pH.
