OMAFRA field crop specialists in collaboration with Grain Farmers of Ontario (GFO) and members of the Ontario Agri-Business Association (OABA) have completed the annual Ontario corn ear mould and DON mycotoxin survey. Corn ear moulds such as Gibberella and their corresponding mycotoxins occur every year in Ontario. These mycotoxins, particularly deoxynivalenol (DON, also referred to […]

It was nice to catch up with everyone at the first Simcoe breakfast meeting of the season on Wednesday, April 10th. John Hussack chaired the meeting, which focused on the condition of the winter wheat crop. At John’s suggestion, learnings from winter meetings were also discussed. Winter Wheat The big question right now is […]
The 2018 corn harvest that many might rather forget is finally past us… yields were high but unfortunately so were DON levels in many parts of the province. Many farmers chose to dry and store their high-DON corn rather than sell it at harvest, in hopes that better marketing opportunities might open up. As long […]
This article was written by Dave Hooker and Albert Tenuta, on behalf of the Ontario Corn Committee Purpose Although 2018 was very challenging to growers and the rest of the corn industry, it presented an opportunity to compare hybrids for DON accumulation across several locations of the Ontario Corn Performance Trials. The main purpose […]
This article was written by Ben Rosser, OMAFRA Corn Specialist, and James Dyck, OMAFRA Engineer- Field Crop Conditioning & Environment A number of growers cleaned corn this fall in efforts to reduce DON. Whether it is on the combine or at the bins, the general message is to remove as much fines or cob as possible as […]
In properly ensiled corn silage, research has not shown an increase in mycotoxins from levels in the crop at harvest. Fusarium species, the fungi that produce DON, do not like low oxygen, low pH environments, so if corn goes through the proper ensiling process fusarium should no longer be active and able to produce DON. […]
Some corn harvested in Ontario this year has concentrations of toxins from ear moulds that are elevated to levels that are too high to be used in animal feed. This could lead to questions about what can be done with this corn, either prior to or after processing. Land application is a possibility. The following […]
While growers are encouraged to find all avenues possible to clean or market their corn, with elevated ear moulds in the 2018 Ontario corn crop, there may be fields with DON levels that render the crop unmarketable. These fields will require destruction in preparation for the 2019 crop season. Destroying a corn crop at harvest […]
End Uses for Mouldy Corn in 2018 Harvesting is of course the preferred option but for some producers finding a market for mouldy or corn with high levels of DON content can be difficult this year as well as it takes time to find alternative uses or streams for this corn. Livestock producers, especially those […]
STORAGE TIPS FOR MOULDY CORN! 1. Harvest infected fields early, and dry corn as soon as possible after harvesting. Do not store wet grain overnight in trucks, wagons, or bins. 2. Dry corn using high-temperature drying, to 15% moisture or less. This stops mould growth and mycotoxin production, but does not reduce mycotoxins already present. […]
HARVEST TIPS FOR MOULDY CORN! 1. Prioritize your corn harvest and storage. Do not mix old crop (2017) or low DON corn with potentially mouldy corn from this harvest. Livestock producers, especially hog, will want to scout fields, sample and test for mycotoxins in order to store their cleanest corn for feeding purposes. Cash croppers […]
