Big machines like seed producers and oil companies are extremely lazy when it comes to dealing with inevitable contingencies. Stockpiling food seems like a defensive strategy to me. A better approach would be to proactively encourage seed stock variety even if those seeds do not have a high yield. Then when something like this happens it will be much easier to pick a resistant strain from the naturally diverse population. Overall average production and profits might go down but there won't be any spikes in crop loss because of lack of diversity.
