Mr. Chair, I could address the second and the third question.
The second question about choosing the best product is quite a complex decision, which ultimately is the farmer's decision, based on a book that is about an inch and a half thick and is updated annually. That's a list of all of the registered products in Canada. That would be a starting point, basically. But primarily it's a long-range planning activity that you do in order to choose the best product for that particular year, which will control the pests you have, and which is safe to use, economical, and that you've had good experience with.
More, and increasingly, it's a matter of planning for years hence; in other words, keeping track of whether there's a soil residue to be concerned with in the year after, or the year after that. That's something else that you consider when you're choosing the product you use. As Pierre mentioned, I think foremost in a lot of the grower's minds now is planning herbicide or chemical rotation so that you are not repeatedly using the same groups year after year and fostering a resistant population in your fields. It really is a complex planning equation, and I would say that most growers are planning four and five years, and longer, in advance, in terms of what's going to be used on certain fields and in what year.
The advent of resistant populations is something that is increasingly catching the attention of growers. We're becoming more educated about it and devising strategies to become more diverse in terms of cropping and in terms of products we use to alleviate that risk from developing.
That would be some of the thinking as far as choosing products that are used on our farms. The other thing is that we don't always do something; we would rather not. Particularly, when an insect population starts to arise in a crop, it doesn't necessarily mean that we control it. Farmers are fairly skilled in evaluating the level of risk from that insect, and if the population is not high enough to warrant a control measure, we don't do it because it costs us money. I think as time goes on, farmers are getting better and better in terms of making accurate decisions on whether something is required or not.
