Using agronomy, biocontrol and outreach to reduce blackleg of potato

Project Details

Status: Completed
Investment: $200,100
Commodity: Potato
Organization: University of Lethbridge
Investigator: Michele Konschuh

Dickeya are particularly aggressive emerging pathogens in North America, causing yield reductions between 20 - 25%.

Why is this research important for Alberta ag?

Numerous seed-borne diseases have been identified in potato production world-wide that are of concern to Albertan growers if they become established within the province. One such disease is blackleg. Blackleg is caused by a number of Pectobacetrium and Dickeya species. Dickeya are particularly aggressive emerging pathogens in North America, causing yield reductions between 20 - 25%. There is no known chemical solutions for blackleg, so the best prevention method is ensuring a clean seed supply. For this to be effective, early identification and rapid diagnostics in the seed supply chain are needed.

This research will use a multi-pronged approach to reduce or eliminate blackleg in potato seed production. Researchers will first focus on developing methods to detect blackleg in storage before the disease has a chance to spread in the storage bin. Secondly, the focus will be on antimicrobial products that have shown potential in helping eradicate blackleg and soft rot.

What benefits can producers expect from this research?

This research will help prevent chronic and acute losses caused by blackleg and soft rot using environmentally sustainable methods. Research efforts are focused on applying technologies and management practices in real world settings and overcoming barriers to grower adoption.

Beyond direct benefits to growers and processors, there are benefits to the agricultural industry as a whole as it will necessitate developing highly qualified personnel to work within the Albertan agricultural industry.

How will these research findings reach producers on-farm?

Results will be shared through information sessions with producers and through collaboration with the Potato Growers of Alberta. Annual reports will be shared as well as a research summary and two manuscripts following the completion of the project.
