The Saskatchewan Wheat Development Commission is advising farmers to properly apply pre-harvest chemical treatment this month.
Sask Wheat chair Bill Gehl says there is increased public scrutiny for many chemicals and it is always important to apply farm chemicals according to the label information.
He says residues are a major issue for many customers and end-users of Canadian wheat.
Sask Wheat says farmers see benefits of using pre-harvest glyphosate to control perennial weeds, but it is important to time the application when the wheat moisture content is less than 30 percent, or at the end of the hard dough stage.
A thumbnail pressed into the kernel will leave an indent at this stage.
Gehl says it is important for farmers to follow the labels to maintain the global reputation of Canadian wheat.
He says it is a good idea to check with elevators in your area to see if they have any concerns about wheat treated with glyphosate prior to harvest.
He says the grain buyers follow the market closely and know what residues importing countries and customers will accept.
