Well, you know something, you're asking the wrong person if you're talking about seed. As far as pesticide application is concerned, the PMRA also makes sure that a crop-protection product is registered for use. It's on the label: registered for use, depending on what soil zone the farmer is in and where that product could be used, etc. They manage very well, when you talk about southern Saskatchewan and northern Saskatchewan. They manage where the crop protection product can be used and where it can't be used.
