Part of the assessment includes a consideration of the potential to develop resistance. We do look at the rate, the frequency. It has to be a rate that works: not too much but also not so little that it could actually accelerate the types of.... In biology, resistance will happen. It's inevitable to a point, but we do consider it.
In terms of the rate, if the rate is no longer sufficient, the company can always reapply and seek an increase, and then we'll look at it from all the different aspects—human health, environment and value—to see if it's necessary. These processes are driven by industry. We can't go in and change a label unless it's to add mitigation measures and that sort of thing.
