Citrus tristeza closterovirus found in Portugal
The EPPO Secretariat has recently been informed by the Portuguese Plant Protection Service that two foci of citrus tristeza closterovirus (EPPO A2 quarantine pest) have been found in the south (Algarve) during a survey on citrus pests. Eradication measures have immediately been applied and infected plants have been destroyed (9606 nursery plants, and 1529 orchard plants). In Madeira, where a vector of this virus (Toxoptera citricidus - EPPO A1 quarantine pest) had been recently found (EPPO RS 95/007), some infected plants have been found in a small orchard, in the region of Caniço. These plants have been removed and burned. The Plant Protection Service noted that all other results of this survey are negative, and felt that Portugal should still be considered as free from the disease.
