Potyvirus in Korean radish






This sample came in before the winter break from a grower who specializes in Asian vegetables. A bag full of Korean radishes (also known as tae baek)- white & green very large (~6 inches long and ~3 inches diameter) radishes. This sample presented with leaf curling and dark flecks in the root tissue. Never having encountered a Korean radish before, I had to research the seed catalogs online to see if the green shoulders were normal (they are). The sample was in the cooler for too long and the foliage was beginning to deteriorate, so no picture but symptoms were similar to those caused by viruses.

Possibilities: virus or abiotic (herbicide, nutrient deficiency).

Tests done: CMV (ImmunoStrip assay from Agdia), POTY (elisa assay from Agdia)

Results: (-)CMV, (+)Potyvirus

New Diagnostic Reporting System

As of March 1st, the Adams County Plant Diagnostic Clinic is using a new method to communicate with our clients. We have always been anonymously reporting our plant sample results to the National Plant Diagnostic System and now the software has been revised. The upgrade is designed to communicate diagnostic information pertaining to your sample submissions back to you more efficiently. Preliminary and final diagnostic reports as well as billing invoices can now be sent directly to your email address. Ultimately the system is designed to deliver written diagnostic information into your hands within 24 hours of sample receipt and keep you informed the duration of the diagnostic procedure. Naturally with every new database, some bugs will need to be worked out before the system proves to function at its full potential. Hopefully this transition will flow smoothly with very few malfunctions or delays.

During receipt of the new diagnostic emails, we hope to receive input from our clients regarding the quality and efficiency of the diagnostic reports and billing invoices. We welcome feedback regarding the new email system during this transition period. And as always, if you prefer phone calls or paper mail over email just let us know!

Get a better handle on your bottom line profitability from the University of Georgia's Paul Thomas and Texas A&M's Charlie Hall in the latest installment in the Greenhouse Grower webinar series.

One of the most difficult aspects of running a business is assessing the effectiveness of employees. There are many ways to do this, and each has social and economic consequences.

In this webinar, Employee And Management Assessment, Paul and Charlie will present several techniques to evaluate individual and team performance, set performance benchmarks based on your company's situation, and establish the economic parameters to allow you to make fact-based personnel and task-staffing decisions. The establishment of supervisory team performance and upper management performance benchmarks will also be discussed.

Even if you are a very small company, it is useful to know how well the boss is really doing.

This 4-part series, Using Benchmarking To Track Your Recovery Performance, is designed to help you make more informed managerial decisions in the aftermath of an economic downturn that literally turned markets upside down.
