Canola genetics can now manage blackleg quite well, but no matter the crop, growers also need to choose seed that will help them mitigate their risk.

Getting positive results from fungicide

Combining new technology with good agronomics helps result in a positive return from a fungicide application

By
Reading Time: 5 minutes The decision to apply a fungicide in any given year weighs the risk of damage from the disease against the cost of a fungicide application. As the risk for disease has spread across regions and crops, discussions on the economics of disease management can be heard on farms across Canada. But despite a rainy spring […] Read more
Apothecia germinate from sclerotia in the soil. They are tiny but can be in great numbers, releasing billions of spores that go everywhere. The ones that land on canola petals are the concern for sclerotinia stem rot and are the target for fungicide applications.

How to keep sclerotinia infection to less than five per cent

New research shows fungicide applied at or just after 20 per cent flowering is still the best way to stop sclerotinia stem rot from shredding canola profits

By
Reading Time: 6 minutes Like a detective piecing together the timeline of a crime, Dwayne Hegedus has played and replayed the sequence of events from when a sclerotinia-infested petal drops onto a canola leaf to the all-is-lost cleaving of the cuticle. The scientist with Agriculture and Agri-Food Canada in Saskatoon now knows, genetically, what arrows the pathogen shoots and […] Read more

Apply your fungicide where it matters

Climate FieldView is helping growers use imaging combined with historical data for a targeted approach to fungicide application

By
Reading Time: 4 minutes When it is time to make a fungicide decision, D’Arcy Hilgartner weighs several factors. Is the crop at the right stage? What are the current moisture conditions? How has the weather looked throughout the season compared to years past? How much of his crop is likely susceptible to disease? Today, he can access all of […] Read more

Digital supercluster backs precision fungicide development

Project aims at wheat leaf rust, reducing pesticide load

By
Reading Time: 3 minutes A West Coast ag tech company in the crop pest control business is setting its sights on wheat leaf rust, with support from one of Canada’s five research superclusters — but not the cluster you might expect. Out of the five federally-supported superclusters launched in early 2018, Protein Industries Canada has been most closely linked […] Read more
Managing for higher yield often entails higher plant densities and fertility as well as timely use of fungicides.

Risk versus reward in the quest for higher corn yields

More quality criteria are steadily creeping into the conversation on corn

By
Reading Time: 5 minutes Farming is known for its learning moments, and one key lesson to come out of the 2018 growing season was that the chase for higher yields doesn’t come without risks or hazards. Or, as is said with maybe equal justification, no good deed goes unpunished. The past 10 years have seen incredible growth in corn […] Read more

White mould in soybeans hits back

Vigilance is needed for a disease that’s still on the rise in many parts of Canada

By
Reading Time: 6 minutes Ask any grower about their soybean crop and the discussion might lean in a number of directions. It might turn to managing tough or resistant weed species in Eastern Canada, or the growing opportunities for the crop in Western Canada. If and when talk turns to diseases and pests, it’s more likely to concentrate on […] Read more

UPL to buy crop chem firm Arysta

By
Reading Time: 2 minutes Indian chemical manufacturer UPL has raised the financial backing for an all-cash deal to become what’s expected to be the world’s fifth biggest crop chemical firm. UPL on July 20 announced it will pay $4.2 billion to buy 100 per cent of Arysta LifeScience — the maker of Everest and Inferno herbicides, among other products […] Read more
“I can’t tell you how often I hear, ‘Oh, it’s just a fungicide, fog it in. Pesticide drift is pesticide drift, whether it has instant visual damage or economic damage, or not.” – Jason Deveau, 'Spray Guy'

‘Spray Guy’ puts the nix on ‘cavalier’ fungicide application

Fungicide drift should earn the same prevention as herbicide, according to one of Western Canada’s best-known spraying experts

By ,
Reading Time: 3 minutes Most farmers are more worried about drift if they’ve got herbicide in the tank, but at least one spray expert says those same concerns should apply to fungicide and insecticide. “I can’t tell you how often I hear, ‘Oh, it’s just a fungicide, fog it in,” said Jason Deveau, the fondly nicknamed “spray guy” from […] Read more

Consider canola crop’s potential yield before spraying

By
Reading Time: 3 minutes As July approaches and crop canopies close, sclerotinia will be on the minds of many canola growers. But will it pay to spray? Fungicide applications are more likely to be profitable when the canola hits 30-40 bushels per acre, said Colleen Redlick, senior technical development specialist at BASF. Justine Cornelsen, agronomy specialist with the Canola […] Read more
If a test finds pathogen populations in a field are overcoming R-gene “A,” the producer can opt to plant seed containing R-gene “B” so the pathogen doesn’t face the same selection pressure.

Another item to put in rotation

A new tool can determine which blackleg genes are in a field, allowing growers to choose a variety that will prolong the life of their resistance genetics

By
Reading Time: 3 minutes A new tool will help western Canadian producers implement “educated rotations” to prolong the utility of blackleg resistance genes in canola, says Dilantha Fernando, a plant science professor at the University of Manitoba. Blackleg is on the upswing in Canada. According to canola researchers, blackleg resistance is starting to break down due to a combination […] Read more
