There could be some sort of terrible blight, but this would unlikely wipe out all crops.
There could be a nuclear attack that poisons the land, but would also kill many people and reduce the food needed.
Most likely option would be a large scale drought, similar to the dust bowl. Highly unlikely and most farms use center pivots to irrigate now so they dont care about rain.
All these things are incredibly remote, to the point its not really worth considering, and if they did have a crisis they could buy food from elsewhere.
