I like Dr. Joe a lot. He is local, from my alma mater and a straight shooter. I like that he calls out other TC educators for teaching nodal and "pulling the wool over people's eyes" so to speak. Nodal does not get rid of Hplvd. Can you TC a node that doesn't have it? Yep. Does nodal eliminate it? Nope. You MUST do meristem to eliminate it and preferably with temp treatments first. Test in, test out, test often. Period.
