 The biggest challenge, I think, is just the shift we've had with less susceptible populations, but also just the management tactics that we're having to do to control these insects. Historically, we've been able to rely on traits. It's come to the point where, with these populations, we have such a wide window. Whether it's egg cats and the larvae feeding or adults emerging, the window seems like it's gotten wider and longer. That's Andrew Penny with Bayer. This is the American Ag Network. I'm Jesse Allen reporting.
