The two are not mutually incompatible - it depends on what is  meant
 by 'routine' Solke:-)  In the case of my own bacteriology 
laboratory, the  PCR test for Brown Rot is used on all samples deemed to be
 high risk.  Of course as well as being routine, this is also experimental
 because it  does not yet have the status of a statutory test required by the EC. 
That may change.

The point is though,  that these assays are now being used to 
generate results of practical use rather than just to provide material
for publications.

I too would be interested in hearing from other laboratories.
