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 VI U.K. OPTIMISED PROTOCOLS FOR DETECTION AND IDENTIFICATION OF R. SOLANACEARUM

A. DIAGNOSTIC AND DETECTION TESTS U.K.

4. Selective isolation U.K.

4.1. Selective plating U.K.

4.1.2. Incubate plates at 28 °C. Read plates after 48 hours and daily thereafter up to six days. Typical R. solanacearum colonies on SMSA medium are milky white, flat, irregular and fluidal and after three days incubation develop pink to blood-red coloration in the centre with internal streaking or whorling. (see website http://forum.europa.eu.int/Public/irc/sanco/Home/main). U.K.

Note: Atypical colonies of R. solanacearum sometimes form on this medium. These may be small, round, entirely red in colour and non-fluidal or only partially fluidal and therefore difficult to distinguish from saprophytic colony-forming bacteria.] U.K.
