ECODA project number: B.3
Principal investigator: Balakrishnan Prithiviraj
In this project over one hundred canola genotypes were screened for stem rot resistance. However, the screening was not fruitful due to low incidence of stem rot at experimental sites. Similar issue prevailed in the field sites in which seven fungicides were screened for their efficacy against stem rot disease in Eastern Canada.
Testing marine bioproducts for the management of stem rot disease yielded two potential candidates: Ascophyllum nodosum extract (=seaweed extract) and λ-carrageenan. Both the products reduced the incidence and severity of the disease. Further field evaluation of these products is recommended.
