So, there is good news and bad news. Bad news first --
Yesterday I was checking my wound care and noticed I still had some soft spots in a couple of areas. (The stump was doing very well however, save a small spot underneath.) I started to trace the yellow leaves back on their vines and noticed that they led to some soft spot somewhere, either on their own vine, or at the union on the main.
Turns out, it was more SVB. It was clear my control efforts have been inadequate. I found some more areas and decided to cull the plant back to only healthy/uninfested vines. See compost pile.
The good news is that it wasn't YVD or similar. Controlling SVB I understand, even if I failed this year. In the new grower forum I was chatting about Imadacloprid and a grower suggested a foliar spray. I hadn't considered that before, and it seems like a much better idea since you can ensure adequate dosing for the plant. Next year, that is my plan.
So for now, I reapplied granular Imadac. at a high dose. Since it binds tightly to organic matter, I feel o.k. that I won't be contaminating groundwater, etc.
I also think I had problems since I didn't work the granules into the soil. It photo-degrades quite quickly and I suspect that might have contributed to my problem. Working it into the soil, over shallow roots, over 300 ft./sq. just isn't feasible.
