About 2 months ago one leaf near the stump wilted then browned. This happened to leaves randomly on the plant every so often, the stem always stayed perfectly upright. About a month later this happened to all the leaves on a secondary vine about 10’ out. Then this happened to another 3’ out. The occasional wilting kept on happening every week or so. Then 2 weeks later the biggest secondary wilted and 2 days later the whole plant wilted and turned to dust in a week. Any ideas? I’m suspecting phytopthoria or fusarium but it could be something else

Verticillium? Did you inspect the inside of the vine for discoloration? I don't know for sure if it can be known with certainty but fusarium has a red or orangey tinge around the infection. Verticillium in tomatoes would be light brown, maybe?? Not sure phyto has any color.

Not sure that it matters what the disease is, they are all hard to control and you might have one disease one year and a different disease the next year. If you're bringing in contaminated wood chips then you've got to stop doing that. Try mustard or rye or whatever works for the growers in your area. Other crops like potatoes might suffer similar pathogens, maybe you can learn from local farmer what diseases they are dealing with.

Figure out a way to have zero weeds next year as living weeds will host an adversarial
biome. Dead weeds are far better. Dead solarized weeds would be the best of all. Solarizing a 30x 30 area would make a huge difference...?

Should I burn the plants

I'd have to say 'no.' No one gets burned by NOT starting an unnecessary fire. Imagine the headlines. 'Course, Little Ketchup, there, is the King of Fire Pits and Ash Creation, so, maybe lern fer now and in a few yeers, whatever. Safety first. I have yet to upscale even any test-solarization over here, and I think you didn't have a good result, Maurice? Without knowing exactly what the problem is, no drastic action is advisable. And, I'll always say to look to the diet of the plants before any assumptions are made about a potential ailment otherwise. Cheaper, faster, easier & more effective - what we all strive for as a species. Good Luck! eg

Sure, bonfire time. Wood ash is a good fertilizer.
