# Council Directive 93/85/EEC of 4 October 1993 on the control of potato ring rot, Division 3.1.2

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

Collect the heel end cores in unused disposable containers which can be closed and/or sealed (in case containers are reused they should be thoroughly cleaned and disinfected using chlorine compounds). Preferably, the heel end cores should be processed immediately. If this is not possible, store them in the container, without addition of buffer, refrigerated for not longer than 72 hours or for not longer than 24 hours at room temperature. Drying and suberisation of cores, and growth of saprophytes during storage may hinder detection of the ring rot bacterium.
