Verticillium stripe has recently become one of the most important diseases of canola in Canada. Verticillium longisporum appears to prefer cruciferous hosts and poses an increasing problem to canola and oilseed rape production. Plant disease nurseries play a vital role in safeguarding agricultural productivity and global food security.
Striped and crucifer flea beetles are chronic pests of canola grown on the Canadian Prairies and as a result over 99% of canola seed is treated with a neonicotinoid insecticide. The flea beetles are known to differ in their tolerance to the neonicotinoids with striped being more tolerant than crucifer flea beetles. Our current project (Ag Funding Consortium: 2021F062R) has found potential differences in the tolerance of both flea beetle species to the neonicotinoid seed treatments depending on collection region. In addition, the two species have differences in their overall physiology in terms of cold temperature tolerance (striped emerge early in the spring) and flight ability (crucifer flies more actively than striped). These differences may affect the overall distribution of flea beetles within and across regions on the Prairies and have implications for management.
Two species of midge pose a threat to canola production in western Canada. Swede midge is invasive to eastern Canada where it has caused significant economic yield losses. Thus far, swede midge has not established in western Canada, but its geographic range is expanding westward from the northeastern United States. Swede midge could have a devastating impact on the canola and horticultural industries in western Canada. If swede midge continues to disperse westward, early detection will be key to attempting its eradication and preventing it from becoming an established pest in western Canada that requires management using insecticides or other inputs.
Activity 6: Increasing soil carbon sequestration and reducing greenhouse gas emissions will directly address the priorities of reducing GHG emissions and sequestering carbon through agricultural management practices. Activity 7: The coordinated suite of objectives will provide farmers, agronomists, agricultural industry, researchers, and policy makers with information required to manage weeds effectively, anticipate new weed threats to farming systems, and mitigate selection pressure for HR weeds.
This study will explore the possibility of controlling one of the most destructive fungal pathogens of Saskatchewan, Sclerotinia sclerotiorum using mycoviruses isolated from Canada.
This demonstration holds considerable significance for local canola producers due to its comprehensive approach to addressing the intricate challenges posed by diseases like Blackleg, Sclerotinia stem rot, and Verticillium stripe. The primary objective is to narrow the knowledge gap among farmers, recognizing the distinct management strategies required for each disease.
The objective of this field-scale trial is to determine if farms can see agronomic and economic benefits from applying nitrogen-fixing bacteria product in wheat or canola. Producer-cooperators will determine the value of utilizing this product under the typical management practices and environmental conditions of their operation.
New opportunities protecting canola yield from biotic and abiotic stress can be developed by harnessing genetic diversity found in crop wild relatives. However, significant barriers prevent breeders from accessing this variation, impeding crop improvement goals.
Weed surveys have been regularly conducted in annual crops in the Prairie Provinces since the 1970’s. In the 1990’s, a herbicide resistance survey program was also started across the Prairies. The most recent set of general weed surveys was conducted from 2019 to 2023, including herbicide resistance surveys on a subset of the same fields.
Both SaskCanola and Saskatchewan Flax Development Commissions have expressed an interest in having humic acid fertilizer studies conducted. This attention originated from their producer boards and members and was suggested to Agri-ARM as a potential ADOPT demonstration.
Early seeding typically results in better yielding crops, especially for canola, barley, wheat, peas and oats (Weir, 2019). But not all crops can be seeded early. This demonstration aims to show producers how their canola crop may have performed differently based on seeding date.
The project objective was to demonstrate the effects of commercially-available, foliar-applied nitrogen (N) fixing bacteria products on the yield and seed quality of canola grown under varying fertility levels and contrasting environments.
