I'll start, and then Clare can fill in.
Yes, we are aware of it, and certainly on the east coast of Canada we experienced that resistance earlier. Clare mentioned in his comments that we're not seeing it in British Columbia yet, but we're certainly aware that with continued use and with no other therapeutants available, we potentially could see resistance in British Columbia as well. That's why it's so critical to have an integrated pest management program the way other farmers do. They have a variety of therapeutants they can use as pesticides in those kinds of issues.
No, we're not seeing resistance in British Columbia yet. Yes, we are seeing it in Atlantic Canada, so the critical need to have an integrated pest management program for Canada is certainly there.
