You can protect your investment by only using acceptable pesticides – those that are registered for use on your crop in Canada and won’t create trade concerns – and by using them as directed on the product label. Review the 2020 products of concern and talk to your grain buyer to ensure the products you are using are acceptable to both domestic and export customers.
2020 Products Of Concern
This year, there are five crop protection product active ingredients that could create market risks if applied to certain crops. Be aware of the following crop protection products of concern for the 2020 growing season:
Please note: This year, chlormequat was registered for use on oats and barley.
- Before using chlormequat (e.g. Manipulator) on malt barley, growers are advised to check with their grain buyer to confirm contract obligations and acceptance.
- Peas, lentils, chickpeas, dry beans and faba beans treated with diquat (e.g. Reglone) may not be accepted by some grain buyers. MRLs are established in most major markets but are set at low levels in the U.S.; growers are advised to consult their grain buyer before use.
- Western Canada: Growers are advised to not use glufosinate (e.g. MPower Good Harvest) on lentils as a crop desiccant. Lentils treated with this product will not be accepted by grain buyers. There is an elevated risk of MRL related trade disruption due to missing or very low MRLs in most major markets.
- Eastern Canada: Dry bean growers are advised to consult with their grain buyer before using glufosinate (e.g. Ignite) on dry beans in Eastern Canada. MRLs are missing or set at low levels in most major markets.
- Malt barley will not be accepted by grain buyers if treated with pre-harvest glyphosate. Do not use glyphosate on malt barley.
- Only use pre-harvest glyphosate on barley and wheat once the least mature part of the field is at less than 30% grain moisture.
- Oats may not be accepted if treated with pre-harvest glyphosate; growers are advised to consult their grain buyer before use. Where permitted, ensure the least mature part of the field is at less than 30% grain moisture before applying pre-harvest glyphosate.
- Peas, lentils, chickpeas, dry beans and faba beans may not be accepted if treated with pre- harvest glyphosate due to scrutiny in the global marketplace and low MRLs for some crops in certain export markets; growers are advised to consult their grain buyer before use.
Glyphosate (e.g. Roundup) is under increased scrutiny in the global marketplace. Rigorous adherence to guidelines, including following the label, will help keep this important product in our toolboxes for years to come. Find additional information about managing pre-harvest glyphosate applications for canola, cereal and pulse crops at Pre-Harvest Application of Glyphosate.
- Malt barley will not be accepted by grain buyers if treated with saflufenacil (e.g. Kixor, Heat). Do not use saflufenacil on malt barley.
Updated information for canola growers: There are no market concerns with products registered for use on canola. Canola can be treated with metconazole (e.g. Quash) and quinclorac (e.g. Clever, Facet and Masterline Quinclorac).
