Initial membership The group had signed up 80% of production by May 1933. F. R. Wilcox of the Giannini foundation was the group's leader for its first year. Wilcox later was the chairman of the Prune Control Board.
The United Prune Growers was only one of several attempts to set up a prune pool to control production, but one of the few to sign up the majority of growers. Another attempt in 1932 ended in failure with insufficient signups and pressure from "cut-throat packers".
