Say there's 5 techers that have 200m bushels each. It probably takes 72 hours for that many bushels to sell, plus you have the normal farmer food supply. No techer's bushels will have time to completely sell out before the next techer undercuts him, hence an enormous crash. I would guess prices will take a 4-6 day fall before most of the techers bushels get sold. Once the bushels are all sold the price will go back up but not so high as before because likely techers won't be as big a part of the bushel demand anymore.
