Sustainable Winegrowing With Vineyard Team

With the prevalence of Leaf Roll Three, Red Blotch, and other viruses, accurate and timely detection of viruses in grapevines has never been more imperative. Alan Wei, Owner and Lab Manager at Agri-Analysis LLC in Davis California explains how his lab is using next generation sequencing (NGS) to find new viruses. Currently, polymerase chain reaction (PCR) is the widely accepted method for testing for viruses. This process tests for one gene at time. Next generation sequencing allows labs to test multiple genes at a time and get results much faster.
