Well I told someone, somewhere here in the Hosta threads, that I would give them the info on HVX testing at Purdue University. You can go to their website directly as well.
The Purdue University Plant and Pest Diagnostic Laboratory is a central facility for receiving both physical samples and digital images submitted for identification of insects, plants and plant diseases or diagnosis of plant and pest problems. This service is provided for the specialists and county extension educators of the Purdue University Cooperative Extension Service and Purdue University's research faculty, staff, and students as well as for private businesses and citizens of Indiana.
Per Sample Handling Fee for Routine Diagnosis of Physical Samples and Digital Images:
From within Indiana: $11.00
Outside of Indiana: $22.00
This includes the initial physical or digital sample evaluation, routine plant and insect/pest identification, microscopic examination of diseased plant material, culturing of suspected disease-causing organisms on nutrient media and diagnosis of many plant disorders caused by environmental, cultural, or chemical factors. Diagnostic responses will be sent by US mail, fax or electronic mail.
There will be no additional charge for any follow-up samples that might be requested by diagnosticians who require additional samples for a more accurate identification or diagnosis of the problem.
Additional Fee Assessment-->
Serological testing for certain plant related viruses, fungi, and bacteria: $25.00
*** Contact us for specific tests.
Insect, Plant and other Pest Identification Requiring Additional Time and Resources: $20.00/hr
*** In some instances, necessary tests to identify causal agents, insects, plants, or other pests require additional time and resources (ie. identification using taxonomic keys). An hourly rate of $20 (charged in 15 minute increments) will be assessed for these exceptional samples
They have a great website all about common pests and things here in Indiana that I often research and study on. They also have links and things of interest written by very knowledgable staff and students.
If you are wondering whether that funny-looking hosta in your garden is infected with a virus, the best way to be sure is to have it tested. Both Iowa State University, Ames, and the University of Illinois, Champaign, offer testing.
n In Iowa, samples may be sent to the ISU Plant Disease Clinic via area county extension offices or directly to 351 Bessey Hall, ISU, Ames, IA, 50011. The cost is $10 per sample. For more information, call the clinic at (515) 294-0580.
n In Illinois, samples may be sent to Plant Clinic, 1401 W. St. Mary’s Road, Urbana, IL, 61802. The cost ranges from $12.50 on up, depending on the sample. For information on how to collect and submit samples, visit the Web site http//plantclinic.cropsci.uiuc.edu. The clinic is open May 1-Sept. 15. For more information, call (217) 333-0519.
I think this is very good information. Previously HVX testing was thought to be expensive and now it is coming down in price which makes it more readily available to people who have concerns about HVX in their gardens.
