Sensing the opportunity to reap great profits by selling fruit to hungry urban consumers back East, nineteenth-century entrepreneurs flocked to California to establish commercial orchards and citrus groves. Invasions of fruit pests, however, threatened years of investment and patient cultivation, and made the public wary of the uneven quality of California fruit. In this article, Mr. Seftel describes how fruit growers organized and called on government to check the menace. Between 1880 and 1920, orchard owners created an elaborate regulatory network, linking local, state, federal, and academic institutions with their enterprise. These fruit-growing capitalists came to believe that only compulsory compliance with government-enforced pest control regulations could ensure their success. During these four decades, the growing horticultural bureaucracy helped transform California fruit growing from an entrepreneurial venture of uncertain promise into the state's second largest industry.
