The fungal pathogen Helminthosporium solani causes silver scurf, a disease that is hard to detect, both in the soil and on harvested potatoes. The disease reduces yields and affects the appearance of the tubers, especially after storage. Fresh potato marketing strategies are based on plastic packaging and the appearance of the potatoes plays an important role. Sensitive, accurate, and affordable silver scurf detection tests are needed to reduce losses. Quantitative PCR (qPCR) tests on soil samples or potato tubers can be used to determine infection thresholds above which the risk of economic loss at planting or after storage is too high. These innovative models for quantifying and estimating the economic risk of disease transmission are a key factor in maintaining and enhancing the competitiveness of Québec potato farms.
