Measuring sclerotinia resistance

By
How exactly do researchers and plant breeders separate the susceptible from the partially resistant? They use the stem test. The stem test simulates natural sclerotinia infection of canola, Lone Buchwaldt of Agriculture and Agri-Food Canada explains. Typically spores colonize petals that adhere to the plant stem. The leaf axle is a hot spot for infections, […] Read more

More sclerotinia resistance coming soon

Researchers are identifying lines with more-robust sclerotinia resistance

By
There’s good news on the horizon for growers and agronomists wrestling with sclerotinia in canola. Researchers with Agriculture and Agri-Food Canada (AAFC) have identified several canola lines with more-robust resistance to sclerotinia. They’ve also learned more about the sclerotinia pathogen and the sclerotinia resistance genes found in some canola lines. Researchers screened nearly 500 Brassica […] Read more

ICE weekly outlook: Canola runs into headwind

By
CNS Canada — ICE Futures Canada canola contracts are running into major upside resistance from a chart standpoint, with a turn lower more likely than additional gains in the near term. “The demand component for canola remains quite strong, although domestic crush margins have diminished,” said Mike Jubinville of ProFarmer Canada. Soyoil futures at the […] Read more

Spraying your fungicide in “the zone”

With Bayer’s new “Zone Spray,” farmers can skip the fungicide in some parts of the field

By
If Warren Bills has his way, farmers will have a better way to forecast sclerotinia than the old wet boots and weather test. “We believe there is a better way to manage the risk of that disease and the returns growers get when they spray,” Bills told agronomists and industry at Bayer’s Ag Summit in […] Read more

Imports and exports by the numbers

Russia is rising and South American beans are finding easier pathways to the ports

By
Changes to grain handling and transportation infrastructure in two key regions of the world will impact Canada’s competitiveness. These areas are the Black Sea region and South America. Russia’s overall grain production (wheat, barley and corn) has grown 70 per cent in the last 10 years to 94.5 million tonnes. Exports have had their ups […] Read more

Keep your canola standing strong against flea beetles

Agronomy tips... from the field

By
When coming up with a flea beetle defence strategy, it’s important to remember that flea beetles overwinter in your field as adults. That means they’re right there, just waiting to feed as soon as your canola crop emerges in the spring. Canola seedlings can compensate for flea beetle feeding and recover — just so long […] Read more
