Sask Wheat Chair Bill Gehl says that with the increased scrutiny that many chemicals are receiving, especially from export markets, it’s important to always apply them correctly.
He notes chemical residues are a major issue for many customers and end users of Canadian wheat.
Farmers who use pre-harvest glyphosate to control perennial weeds should remember to limit their application to when the grain moisture content in wheat 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.
