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. It takes at least three…
OMAFRA Field Crop Team November 19, 2018 1866 Comments Off on Land Application of Crops and By-products with Elevated DON LevelsSome 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 rules apply to corn or…
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 will present challenges for 2019,…
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 with hogs, cannot feed high…
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. Low-temperature drying takes much longer,…
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 are advised that the same…
