We've developed BT technologies. We've worked very, very closely with the regulatory systems here in the U.S., and now in Asia, China, and India, to guarantee that we have built natural refuge systems where we can ensure that there's no buildup of resistance. That's the first leg of the strategy. The second leg is that we're constantly looking for new genes, so that we continue to present the insect populations with additional challenges to avoid the buildup of resistance. But it's something that, as a commercial enterprise, but also as a farming community, they take very, very seriously.
Nobody wants to go back to spraying ten applications of insecticide.
They're growing a cotton crop in Australia in some areas that they couldn't grow cotton before, because the insects had developed resistance to synthetic insecticides. So there's a community around the world that's very focused on avoiding the buildup of resistance. The refuge strategy depends on sort of compliance. We set a contractual obligation with growers, when they buy our seed, to maintain refuges. That is monitored closely, and it's to the extent now in the U.S., that if a farmer does not abide by that refuge program, we refuse to sell him seed that second year. . . .
