If you are really interested in learning about grapevine trunk diseases, this new journal article is for you (see link). It is a highly scientific article which covers the state of the art relative this topic. We mainly have issues with Botryosphaeria-type diseases, and I include Phomopsis in this category as well. However, we have identified Petri disease previously, and I bet we have more of this disease on stressed vines than we realize. If you get bored with spending quality time with family over the holidays, I have provided a gift for you. In all seriousness, I hope each of you can spend time with family and relax a little over the next week or so. Looking forward to a new and productive year.
