Lactating dairy cows or growing beef cattle require amino acids for milk production and growth. These amino acids are the "building blocks" of milk protein and skeletal muscle.

The best defense against fall flea beetle damage to canola seed yields was to seed at mid-May or earlier. Seeding date had the greatest influence on harvest parameters for all factors investigated, and in most trials earlier seeded plots outyielded later seeded plots.

Blackleg continues to be found throughout the canola growing area and new strains of Leptosphaeria maculans have been observed in western Canada.

Sclerotinia sclerotiorum is one of the most important pathogens affecting canola and other susceptible crops such as dry bean in western Canada. In canola, even a yield loss of 3% would cost producers approximately $13M yearly.

Researchers in Saskatchewan conducted a three-year trial from 2006 to 2008 to assess the potential of pushing canola as a pre-harvest management option compared to swathing, pushing and/or desiccating, and straight cutting canola.

Juncea canola can be considered as an alternate oilseed crop that is adapted to the semiarid areas of the northern Great Plains where high temperature and drought stresses often limit the productivity of conventional napus and rapa canola species.

Most of Canada’s canola crop is produced using certified seed. With rising input costs, some producers are tempted to save and replant seed (farm-saved seed) grown from a hybrid variety.

In Canada, Aster Yellows Disease (AY), caused by ‘Candidatus Phytoplasma asteris’ affects several economically important crops including canola. Until recently, the disease has been considered to be of little importance, however, in 2007 crop production losses were higher than estimated with the visual AY assessment.

The clubroot pathogen, Plasmodiophora brassicae is now established as a pest of canola in central Alberta and may be spreading to other regions of the province.

Ecoclimatic modeling indicates that most of Canada is suitable for establishment of swede midge, including most of Saskatchewan. In 2007, swede midge were found in three fields in Saskatchewan for the first time.

The first objective of this study was to investigate the effect of production practices on the quality and vigour of open-pollinated Argentine canola. Seeding date and swathing time of the mother crop had a significant effect on seed quality.

The objective of this study was to investigate the effect of seed quality on the performance of hybrid Argentine canola in early- and late-seeded plots with conventional tillage and minimum tillage.

The objective of this study was to investigate the effect of seeding rate on flea beetle damage and agronomic performance of open-pollinated (op) and hybrid Argentine canola.

Diverse crop rotations are known to reduce the quantity of soilborne pathogens, while the continuous planting of any crop increases diseases and pests specific to that crop, causing a reduction in the yield.

The objective of this study was to investigate the effect of seeding date and seeding rate on the agronomic performance of open-pollinated (op) and hybrid Argentine canola in conventional tillage (CT) and minimum tillage (MT).

The objectives of this study were to determine the effect of neonicotinoid seed treatments on flea beetle damage and the performance of Argentine canola seeded in early and late May.

The objectives of this study were to determine the effect of neonicotinoid seed treatments on flea beetle damage and the performance of Polish canola. Seed treatments reduced flea beetle damage and improved the performance of open-pollinated and synthetic Polish canola in all tests.

Field studies were undertaken in southern Alberta and Saskatchewan during the 2006 field season to investigate different management strategies for enhancing the effectiveness of natural enemies of cabbage seedpod weevil and diamondback moth in canola.

Sensor-based N management appears to have potential for enhancing agronomic N-use efficiency in canola production and, provided that the risks and benefits of sensor-based N management are managed appropriately, economic profitability for canola producers.

In this research project, the two main objectives were to investigate the responses of major insect pests and the Blackleg pathogen of canola to the two bacterial strains, Pseudomonas chlororaphis (PA23) and Bacillus amyloliquifaciens (BS6), plus jasmonic acid.
