Under the collaboration between DOA-DOAE [Department of Agriculture-Department of Agricultural Extension] and Thai-German IPM [integrated pest management] in Selected Fruit Tree Project, the Nursery Production Program initiated the production of disease-free citrus in Thailand. National Citrus Foundation Block was established under the management of DOA and certified budwoods were released to the Approved Private Nursery under the Nursery Accreditation Scheme. Disease-free citrus cultivars budded on Phytophthora tolerant rootstocks i.e., Troyer, Carrizo, and Volkameriana are commercially propagated and released to major growing areas of the country. It is highly recommended that disease-free citrus should be cultivated in an isolated area at least 5 km away from disease infected citrus orchards. Replanting disease-free citrus trees in established orchard is prone to be re-infested by the disease within 1-2 years. Study on the management to prevent reinfestation of greening and triztesa showed that chemical sprays at 7 day-intervals in the first year could prevent invasion of insect vectors and reduce the risk of disease occurrence
