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

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

Fields of unharvested corn were common around parts of Ontario, with many fields affected by Gibberella ear rot, leading to issues with DON.

Researchers discover a way to eliminate almost all DON toxicity in corn

A detox for contaminated corn may be just around the corner

Reading Time: 5 minutes As farmers think back to the challenges of the 2018 growing season, learning to deal with DON is probably top of mind. Indeed, it really was one of, if not THE worst year ever for managing the impacts of deoxynivalenol. Not only did growers have trouble harvesting their infected corn, but delivery also became a […] Read more


Guess who’s paying for new grain grading?

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

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

The corn sector has fallen behind in dealing with ear rot diseases at that same time those outbreaks have worsened.

2018 delivered many DON lessons for corn

Last fall’s weather was partly to blame, but so too were the lack of management options and strategies

Reading Time: 6 minutes There can be little doubt that 2018 will go down in the record books as the worst year in Ontario for dealing with ear mould in corn and contamination by deoxynivalenol (DON). Wet weather through silking and then again in much of October and November challenged growers getting into their fields for timely harvesting of […] Read more


Grain grading revamp may add falling number, DON as factors

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

How Ontario’s new DON testing cost-share program works

Reading Time: 3 minutes With vomitoxin (DON) levels so prevalent in this year’s corn crop, the Ontario Soil and Crop Improvement Association (OSCIA) says a new DON testing cost-sharing initiative will help producers strategically market their grain. Why it matters: OSCIA says cost-sharing will help farmers know how severe their deoxynivalenol (DON) issues are, and how to market their […] 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

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
