I'm sorry, but this is completely wrong. California canning peach farmers are organized and crop prices are set by industry-wide bargaining with processors every year. Additionally, now that Del Monte is out of the business, the only remaining operating canneries are owned by a grower cooperative. It didn't save the industry. In fact, it may have led to the irrational planting of these trees that now need to be pulled. Source: my father was a peach farmer and chairman of the board of the California Canning Peach Association for many years. But he saw this coming and got out of the business.
I’m an agronomist and while I don’t directly deal with that level of things, what you wrote sounds roughly like what goes on for the hazelnut industry here in Oregon.
