Found an excellent discription of various diseases from the University of Florida.
Outdoor growers have to know this stuff. Indoor hopefully not so much. 🙂

University of Florida extension service
Until we bring it in from a food crop.
Or until the food crop down the road 300 meters goes surry and the dude just lets it fallow.
Outstanding link. Thanks for the post. Should be a sticky or one of the quick links we give to new outdoors folks.
 
Before the internet, there was this thick ass book, symptoms and illness. You could look up any symptom to see what’s wrong with you. My wife would have a headache and look it up and think she had brain cancer. Lots of laughs. When I look at the pictures on the marijuana diseases, I think my plants have all of them. Dang it, I’m back in the same trap!

My daughter was like that when she was little. She learned to read early and read everything, even the books not age appropriate. LOL

I was nervous that I had miss diagnosed mine until I got to the Septoria pics. I did not see Verticillium listed, but maybe the fields in Florida don't have it. Might get too hot down there.
 
Question is...what can be done to remove the pathogens from the soil.

Only thing I've found was about solar heating the soil. Cook it out, give it a fever, so to say.

I wonder if burning brush, tree limbs, ect. would help. I've been burning stuff like that, in my garden every fall, after harvest, and during spring clean up of the yard.

Gotta pile ready for this fall, and a bunch more tree branches that need pruning, once the leaves come off.
 
You can not burn pile that pathogen out of the soil. Burn piles are low and slow to preserve nitrogen and phosphorus components.
A burn out sterilizes the soil and to grow stuff you will need to rebuild the soil.
Solar heating will work where you lay out black tarps in direct sunlight but will reduce pathogens to a normal balance in the soil. They are always present. If the local environment gets wet and cool shit gunna happen.
Prolly lost 1500 melons, whole bean plots and had to move corn 3 times over a 25 year food hobby.
Gave up on potatoes.
