Textual Amendments

F1 Substituted by Commission Directive 2006/63/CE of 14 July 2006 amending Annexes II to VII to Council Directive 98/57/EC on the control of Ralstonia solanacearum (Smith) Yabuuchi et al..

SECTION I U.K. APPLICATION OF THE TEST SCHEME

2. Scheme for detection and identification of Ralstonia solanacearum in samples of asymptomatic potato tubers U.K.

Principle: U.K.

The testing procedure is intended for detection of latent infections in potato tubers. A positive result from at least two screening tests ( ³ ), based on different biological principles, must be complemented by the isolation of the pathogen; followed by, in case of isolation of typical colonies, confirmation of a pure culture as R. solanacearum A positive result from only one of the screening tests is not sufficient to consider the sample suspect.

Screening tests and isolation tests must permit detection of 10 ³ to 10 ⁴ cells/ml of resuspended pellet, included as positive controls in each series of tests.]
