[Interstellar] Donald says that this is the last harvest for okra, ever. What made him say that?

I’m going on memory here, so bear with me if some of the finer details are fuzzy or turn out to be wrong (somebody will probably correct me if so).

The blight that was destroying crops across the planet seemed to have a disproportionate effect on different crops. Most farmers were growing corn, as it was apparently a safe crop. Okra was too until recently. The blight was evidently changing over time, so it had begun to affect okra, and it’s later revealed that corn will eventually be affected by it too, hence NASA’s urgency in “solving” gravity and/or colonizing a new planet.
