Absolutely.
As you stated correctly, the issues that we saw in isolated pockets seemed to be related primarily to corn—which is generally a dustier crop than is, for example, canola—and to some of that seed coating actually coming off of the corn. With certain planting equipment that uses air and vacuums, that exhaust is blown out with some of that seed coating on it.
The industry, as you noted, worked with the regulators and worked with the seed industry and with growers to tackle that issue head-on. Even though it was isolated in very small pockets, we instigated widespread measures. Farmers were adding a lubricant, which was like a talc powder, to help the corn seeds flow through those big pneumatic drills, which was abrading some of the products off. The industry came up with a new product that's more of a wax-based powder and that significantly reduces the amount of dust coming off the pneumatic seeding equipment.
We can't attribute all of the diminishment of incidence to those measures, but we did see a 70% reduction in the number of incidents being reported at the time of planting, and certainly those measures contributed to that.
