Next generation fungicides – translating DsRNA technology from the lab to the field

mca2022dev on March 14, 2023

This project will investigate the application of RNA-based fungicides to control major diseases of crops grown on the prairies, namely wheat and canola. This approach is based on proven research that has demonstrated that the application of RNA molecules directly as a spray can target and silence functionally important pathogen genes. Induction of gene silencing kills the pathogen and prevents further disease formation and spread. Additionally, the systemic nature of RNA-based fungicides can reduce the risks associated with timing of fungicide application to control disease.

Next generation of prairie herbicide-resistant weed surveys and surveillance

mca2022dev on March 14, 2023

This project covers the first three years of a larger project to determine the status of herbicide-resistant (HR) weeds in the Canadian prairies from 2019 to 2023. The project will use a series of provincial HR weed surveys to provide current information on the size, extent, and order of importance of HR weeds in each prairie province, ecoregion, and jurisdictional area. This information can be used by growers, agricultural industry, and researchers to set priorities and identify problems which impact agricultural production currently and also in the near future.

Beneficial practices for soil and water quality, excess water management and drought resiliency in an undulating soil landscape in Southwestern Manitoba.

mca2022dev on March 14, 2023

Tis study will help the agricultural industry through knowledge building, demonstration and capacity building in soil and water and salinity management in undulating landscapes in SW MB. Tile drainage is an emerging practice in this extensive and socio-economically important region of MB, as producers look for means to reduce soil and climatic limitations to annual crop production. Producers in this region are poised to make significant investment in water management infrastructure and BMPs. The study and establishment of the demonstration site will help guide industry and producers in this investment through the implementation of effective improvements to achieve management objectives sought.

Genetic analysis and genomic selection models for leaf rust resistance in western Canadian winter wheat

mca2022dev on March 14, 2023

Results from this research will be directly applied to winter wheat variety development at the University of Manitoba and Agriculture and Agri-Food Canada. CWRW breeders will benefit from an improved understanding of the leaf rust resistance in our germplasm and from the ability to predict leaf rust resistance using GS models and marker-assisted selection. This will translate into improvements in selection accuracy and increased efficiency in our breeding programs.

Mitigation and management of Cry1F resistance in European corn borer in Canada

mca2022dev on March 14, 2023

The distribution of Cry1F resistance and the status of Bt susceptibility in Canada will be measured by screening ECB collections from different regions in laboratory bioassays. This work will be conducted over multiple years to determine the current range, spread, or containment of Cry1F resistance. This research will allow verification of single nucleotide polymorphism (SNP) markers as a tool for identification of field-evolved Cry1F resistance. This would enable quicker confirmation of resistance and faster mitigation responses for resistant populations, thereby sustaining Bt technology and reducing economic losses to producers.
