Nut loosening cracked in California

What strategies are available for walnut growers to loosen their nuts?

One possible method is provided by the Fruit and Nut Research and Information Center of the University of California at Davis. “A land-grant institution built to advance the human condition through improving the quality of life for all people of California, for all citizens of our nation and for the rest of the world.” For nut loosening purposes they recommend (via their extensive Walnut Research Reports) the application of 2-Chloroethylphosphonic acid.

Comprehensive details of the university’s techniques can be found here, here, and here.
