By 1925, the researchers had determined that Acala cotton, named after Acala, Texas, was the highest-quality variety of long-staple cotton; they then developed the "one variety" method of cotton production, in which every California cotton producer would grow Acala cotton. As a result of this research, the state of California enacted the California One Variety Cotton Act, which mandated that California cotton producers could grow only Acala cotton. The law spurred the growth of California's fledgling cotton industry, which now forms a major part of the state's agricultural economy. The success of the "one variety" policy caused the station to earn an international reputation for its research, and procedures developed at the station have been used in the Australian and Israeli cotton industries.
