First of all, as I indicated in my opening remarks, we do have sales reporting requirements for the manufacturers. We have been collecting that information since at least 2008.
The trends in pesticide sales and use in Canada very much follow trends in agriculture, since that's perhaps the major sector using pest control products. In some years there are increases in pesticide use, based on agricultural production. In some years, for example, use of specific types of pest control products such as agricultural fungicides tends to increase. For example, in a very wet growing season sometimes more fungicide types of pest control products are required than was the case in previous years.
