# Commission Directive 2006/56/EC of 12 June 2006 amending the Annexes to Council Directive 93/85/EEC on the control of potato ring rot, Division 5.3.4

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

There are several problems inherent to the specificity of the FISH test. Background populations of fluorescing cells with atypical morphology and cross reacting saprophytic bacteria with size and morphology similar to C. m. subsp. sepedonicus may occur, although much less frequent than in the IF test, in potato heel end core and stem segment pellets.
