GFO: Mould survey
Results from the 2019 Ontario Grain Corn Ear Mould and DON Mycotoxin Survey have been released.
OMAFRA field crop specialists in collaboration with Grain Farmers of Ontario and members of the Ontario Agri-Business Association have completed the annual provincial corn ear mould and mycotoxin survey. The survey found 96% of samples less than 2 parts per million for DON which is considerably lower than 2018.
While 96% of 2019 samples tested below 2 parts per million, it is important to remember that growers should remain vigilant and be aware of management options in those fields with higher ear mould and DON concentrations. Ear moulds and mycotoxins occur every year in Ontario and fields need to be assessed individually.
