A bit of a potato centric answer for you I'm afraid:

I know of one company in the UK that uses dot blots to detect potato 
viruses in tubers.  We (Scottish Agricultural Science Agency) use dot blots
 to detect potato spindle tuber viroid in potato plants received in our 
quarantine facility.  

PCR is routinely used in the EC for testing for Pseudomonas 
solanacearum (Brown Rot of potatoes) and Clavibacter michiganensis 
subsp. sepedonicus (Ring Rot of potatoes). 

There are also PCR-based tests for potato cyst nematode 
identification that are coming into routine use.

If you get any replies by email, please repost the information here 
as this is a subject of interest to many of us.

Hope this is helpful.
