| Abstract: | Citrus tristeza virus (CTV) causes a most destructive citrus disease in many parts of the world, and indications of natural spread were found in Israel in 1970. The strategy for controlling the disease in Israel is based on the eradication of virus-infected trees, detected by test plants or immunological methods. Mathematical models for CTV infection and spread were developed and used to assess the cost-effectiveness of the eradication policy. It was concluded that the discovery-eradication program is economically justified and superior to allowing the disease to progress unchecked. |
