A great resource for managing potato viruses has been updated:
There have been two important updates to the Management of Potato Tuber Necrotic Viruses website. Both updates can be found under Tools and Resources.
% Disease Estimation and Sample Size Tools: The information and Excel tools on this page will allow you to more accurately estimate the % disease in a seed lot along with a range (confidence interval) based on risk tolerance. These tools will also allow you to determine the sample size needed for a specified target % disease and risk tolerance. There are separate tools for “Individual Tuber/Plant Samples” and “Composite Tuber/Plant Samples”.
Certified Seed Purchase – 10 Questions to Ask: Ask these 10 important questions to ensure you are buying the best seed possible for your farm, updated with the improved % Disease Estimation information noted above.
