Situation of several quarantine pests in Germany in 1998
The NPPO of Germany has informed the EPPO Secretariat of the following:
Clavibacter michiganensis subsp. michiganensis (EPPO A2 quarantine pest) and Liriomyza bryoniae (EU Annexes) were found in 1998 in Sachsen on tomatoes grown under plastic (1;ha). All infected plants were destroyed. The status of both pests in Germany can be described as: Present: only in some areas.
Liriomyza huidobrensis (EPPO A2 quarantine pest) was found on tomatoes in a nursery (5000;m²) near Berlin in 1998. Chemical treatments were applied and the pest was found again. The status of L. huidobrensis in Germany can be described as: Present: only in some areas.
Potato spindle tuber viroid (EPPO A2 quarantine pest) was found in 1998 in Nordrhein Westfalen on transgenic potato material (4 breeding lines of potato cv. Bintje) grown in an experimental field of a breeding institute. The viroid was detected by visual observation of symptoms and laboratory tests. The infected potato material was immediately destroyed. The experimental field and surroundings were treated with an herbicide. Visual observations were conducted within a radius of 5 km and gave no result. Surveys will continue to verify the absence of the disease. The status of potato spindle tuber viroid in Germany can be described as: Present: only in one area and under eradication.
Puccinia horiana (EPPO A2 quarantine pest) was found in September 1998 in one nursery in Thüringen on chrysanthemums for cut flower production. Chemical treatments were applied and the disease was not found again. In 1998, the fungus had also been found near Berlin (see also EPPO RS 98/203). The status of P. horiana in Germany can be described as: Present: only in some areas.
