There are still a few areas for which we require information about the Canadian situation. One of them is the case of the residue trials. Residues left from a product used in a field in Quebec might be quite different from those left if the product were used in a field in Florida. We want to try to have the appropriate residue.
Now, this has been recognized as a challenge not just between Canada and the U.S., but more broadly. So there are efforts under way to see what, if anything, can be done about that, to both respect what are called “good agricultural practices”, which will differ, depending upon the area, the climate, etc., and the relation between these good agricultural practices and the maximum residue limits. But we are very aware, especially for minor uses, that it is this testing that's needed that raises costs.
This project tries to make sure that we're looking at finding the minimum that would be needed, or determining whether any is needed at all in the Canadian situation. We're also looking at other approaches to addressing that situation. We're working with the U.S. on crop groupings, and potentially what are called “super-crop groupings”. So again, if within this group of crops you've done tests on two, you'll get an approval for all 15 crop types, as an example.
It remains a challenge, but it's a challenge we're working on.
