Citrus tristeza is among the most serious viral diseases of citrus worldwide. The virus resulted in the loss of 3 million orange trees on sour orange rootstock in Southern California during the 1940s and 1950s. In light of this impact on the California citrus industry, in 1963 a tristeza eradication agency was established in the San Joaquin Valley to survey, detect and remove commercial citrus trees infected with citrus tristeza virus. Five pest control districts were established within the agency. Early survey and laboratory screening by the eradication agency generally detected mild strains of the virus. In 1996, two districts withdrew from the eradication program convinced that the virus was not seriously harming infected trees. The decision was based on the fact that commercial orchards in the districts were generally grown on rootstocks thought to be tolerant of mild strains of the virus.
