# Council Directive 98/57/EC of 20 July 1998 on the control of Ralstonia solanacearum (Smith) Yabuuchi et al., Division

Extent: E+W+S+N.I.

Note: Inhibition of the PCR may be suspected if the expected amplicon is obtained from the positive control sample containing R. solanacearum in water but negative results are obtained from positive controls with R. solanacearum in potato extract. In multiplex PCR protocols with internal PCR controls, inhibition of the reaction is indicated when neither of the two amplicons are obtained.
