Promoting Canadian Oats

Grain farmers must pay attention to two critical issues related to the pre-harvest application of pesticides – applying too early and applying too close to combining.

Pesticide labels spell out “too early” and “too late” for each product and crop.

Not following pesticide labels may result in pesticide residues that could put sales, and Canada’s reputation as a reliable supplier of quality cereals, at risk.

Background

Fall application of glyphosate is of special interest to our customers for two key reasons:

  1. Glyphosate has come under increased scrutiny, when compared to other pesticides, due to recent media attention generated by those who do not support the use of pesticides for any reason;
  2. Unlike many products applied in fall, applying glyphosate when kernels are too green (30% moisture or above) can result in residues that are greater than the maximum allowable limit.

What Can Farmers Do?

  • Always follow the label. Labels on crop protection products have been developed through Canada’s science-based regulatory process. The labels ensure safe use of crop protection products and help ensure that residues do not become a marketing concern.
  • Do not apply glyphosate to cereals when kernels are 30% moisture or greater in the least mature areas of the field.
  • Abide by the pre-harvest interval.
  • Some customers have contract limitations on fall application of glyphosate. Talk to your grain buyers to ensure they know what crop protection products you intend to use, and to confirm that none of these products will cause concern for export or domestic customers.

Farmers’ rigorous adherence to these guidelines, including the science-based label, will keep this important product in our toolbox for years to come.
