Yes, thanks.
Our members are always obviously concerned about resistance development because that means the products are no longer effective, and therefore, are no longer of any use to the farmer. We always try to make sure that through crop rotation and chemistry rotation you're not always selecting for that resistant weed or resistant insect to take over that field. There have been some issues, frankly mostly in the southern U.S., where some weeds have really developed strong resistance to many herbicides including glyphosate and they're having a real challenge there.
We have noted through Agriculture Canada a handful of herbicide-resistant weeds in Canada in limited pockets. Our industry is very engaged in that process with Agriculture Canada and other experts to make sure that those don't become widespread issues like we've seen in some parts.
