MRL Update

Be Aware of Market Risks Involved with Desiccant Use This Season

Although the pulse industry in Canada has made significant progress in developing acceptable maximum residue
levels (MRLs) globally for pulse crop products used in Canada, growers are still advised to be aware of possible
marketing restrictions that may arise from using certain desiccants/harvest management tools this season.
Specific guidelines for products are available on the next page of this document, but growers are also urged to review
all the information in this document before proceeding with plans for their pulse crop products this season.

What are dessicants/harvest management tools?
For pulse crop production in Western Canada, these products include diquat (Reglone), glyphosate (Roundup), saflufenacil
(HEAT), glufosinate (MPOWER Good HARVEST), flumioxazin (Valtera), and carfentrazone (Aim, CleanStart).

What are the risks of using these products as preharvest desiccants?
Unlike most crop protection products used in Canada, desiccants/harvest management tools are applied very late in the crop
year. As a result, growers must ensure that the product residue remains below MRLs set by regulatory agencies, in order to avoid
problems with selling their crops.

What developments have there been on these issues since last year?

While the Canadian pulse industry has been working hard to make international pulse marketing safer and easier for Canadian
Growers, each of the six desiccants/harvest management products registered for selected pulse crops in Western Canada (listed
in the chart on the following page) still has the potential to cause issues in certain crops and markets. Growers are always advised
to be aware of international regulations in order to make the best marketing decisions.
