Grapevine trunk disease program update

October 22, 2019  By Dr. Tom LoweryDr. Jose Ramon Urbez-Torres

Virus diseases, particularly those caused by the grapevine leafroll associated viruses (GLRaV) and grapevine red blotch-associated virus (GRBaV), are a serious threat in all Canadian wine producing provinces due to their rapid spread and severe impact on grape and wine production and quality.

Activities in this theme will determine the incidence of virus infections across Canada, the role insect vectors and their control play in infection spread, and the virus impacts on grape yield and quality.

This activity continues work performed under a B.C. GF2 AgriInnovation Program with increased focus on the role of vectors in the spread of leafroll and red blotch viruses and on long term mitigation. Small lots of wine will be made from infected plants to assess impacts on wine sensory attributes that will be validated by sensory panels.

Agriculture and Agri-Food Canada has released the above video about the successful research on grapevine viruses we have and are still conducting with BCWGC funding support. For more information, CLICK HERE.
