Alberta deregulates fusarium

Crop disease comes off province's 'zero tolerance' list

By
Reading Time: 2 minutes Alberta is moving to keep fusarium in check by means other than the “zero tolerance” policy it has in effect on agricultural pests such as rats, rabies and clubroot. Agriculture Minister Devin Dreeshen announced a ministerial order Wednesday to remove Fusarium graminearum from the list of pests covered by the Pest and Nuisance Control Regulation, […] Read more
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
Diligent screening of susceptible varieties and better fungicide timing means growers are managing fusarium head blight.

New cereal fungicide seeks to carve out its own niche

Cerefit's dual mode of action acts as a preventive and curative

By
Reading Time: 4 minutes In the fight against diseases in winter wheat in Eastern Canada, the agri-food industry has done a remarkable job in effectively managing fusarium head blight — for decades considered the crop’s greatest disease threat. Seed companies have screened and eliminated susceptible varieties while timing of fungicide applications has advanced to the extent that fusarium is […] Read more
The 2018 growing season was bad for gibberella ear rot in many corn fields and it remains a challenge.

Disease outlook for the 2020 crop season

We can’t be sure which diseases will attack this year, but indications are that once they arrive, they’ll be here to stay

By
Reading Time: 7 minutes What will be the big disease concern this year? Will it be tar spot in corn, or frog-eye leaf spot in soybeans? Or will growers be facing more of the same, with soybean cyst nematode and northern corn leaf blight? Forecasting diseases is iffy at best. The truth is that most disease pathogens, once they […] Read more
Giving wheat midge a few susceptible wheat plants to feed on ensures that the resistant population doesn’t eventually take over.

A decade of midge-tolerant wheat

New varieties are in the pipeline for CWRS and SWS classes

By
Reading Time: 4 minutes Over the past 10 years, western Canadian farmers have deliberately seeded 27 million acres of wheat susceptible to orange blossom wheat midge — and saved themselves an estimated $1 billion in lost yield and quality. To be clear, only 10 per cent of the seed on those acres was susceptible to midge, and that’s been […] Read more
FHB infection in barley. The Brewing and Malting Barley Research Institute and the Canadian Grain Commission are testing an innovative post-harvest treatment from a Scandinavian company called ThermoSeed. It has potential to eliminate the pathogen during malting and brewing.

Careful grain sampling key when looking for mycotoxins

Ontario’s worst-ever year for DON infection in corn may provide some guidance for managing the problem in Western Canada

By
Reading Time: 5 minutes For Ontario corn growers dealing with an outbreak of deoxynivalenol (DON), 2018 was a year to forget. “It was a really major, widespread issue,” says Art Schaafsma, a professor in field crop pest management for the University of Guelph’s Ridgetown Campus. He says the last time the industry saw widespread issues with DON was in […] Read more

Guess who’s paying for new grain grading?

New CGC regulations would add DON and falling number to Canada’s grade specifications

By
Reading Time: 8 minutes A proposal by the Canadian Grain Commission (CGC) to add two grading factors to its list of parameters is stirring considerable debate, mostly among members of the western Canadian food value chain, but also in the east. The two factors revealed in a document published by the CGC late last year are falling number (FN) […] Read more

Grain grading revamp may add falling number, DON as factors

By
Reading Time: 3 minutes Two significant grain specs that aren’t yet factors for a crop’s official grade are now under consideration to join that official list. The Canadian Grain Commission on Monday put out a call for “grain sector stakeholders” to submit their views before May 10 on a proposal for falling number and deoxynivalenol (DON) to both become […] Read more

Pearce: Multiple modes of action an emerging reality for fungicides

By
Reading Time: 2 minutes As growers face more challenges from weeds, diseases and insects, many researchers, agronomists, advisers and farmers have shifted thinking from “control” of pests to “managing” them. Some of this trend is attributable to single-mode-of-action products and a reliance on one or two chemistries or technologies — but the adaptability of weed, disease and insect species […] Read more
The falling number test requires laboratory-like conditions, and is usually only done at selected central locations when there is a general concern about sprout damage.

Better than meets the eye?

Canada’s quality-control system still has a lot of support, but some are calling for grades to be determined by machines, not the human eye

By
Reading Time: 4 minutes Is that No. 2 CWRS just as good for milling and baking as a No. 1? Or does that No. 1 CWRS have some quality damage that can’t be seen with the naked eye, making it no better than a No. 2? The answer could be yes in both cases, sometimes, in cases that might […] Read more
